NIGHT OPS
R/C flying at night

NIGHT OPS, 3038 Sylmar, Clovis, CA 93612
Well daylight savings time ended this Saturday. With the days growing shorter and the
nights growing longer, it's dark by the time most people get off work. This spells the end of stopping by the field or slope for some
after-work flying. At least that's what it used to spell...
The Night Ops System I have developed a product that makes flying R/C after dark truly
practical. The system is called "NIGHT OPS" R/C Night Flying Lights. NIGHT OPS installs on any airplane in just a
few minutes, and can be transferred from airplane to airplane just as quickly. The system consists of 6 lamps and a power supply.
The power supply can be placed inside the fuselage or taped to the outside if you don't have room. (I cut cavities in the fuselage of
my foamies). Just remember to put the power supply and battery near the CG. Four of the lamps are flat (I mean REALLY
FLAT). The flat lamps weigh 3.13 grams each and are .009" thick, .375" wide and 30" long. The flat lamps are
attached to the wings with scotch tape. I've been putting 2 flat lamps on the top and 2 on the bottom of the wing. The other two
lamps (wire lights) are round wires 3/32" in diameter by 12" long, and weigh 2.35 grams each. One wire light is taped
on the perimeter of the fin and rudder (don't worry, they're very flexible) and the other wire light is taped around the nose (don't
worry the "wire lights" seem to be indestructible). The power supply is .83 x .68 x 1.0 inches and tips the scales at
30.2 grams. The system runs for 8-10 hours on a 9 volt battery (the system draws about 85 mA). The lamps generate no heat or
RF and are good for about 5000 hours of use. That's it, plug in the battery, turn it on and launch on your first NIGHT OPS.
This setup has proved to be very fly-able. The combination of lights on the wing and
perimeter of the fuselage/empennage allow precise recognition and control of pitch and roll. I know what a lot of you are thinking
"Night flying, this must be pretty tough". I'm relatively new to r/c (less than a year) and find night flying with
"NIGHT OPS" to be no more or less difficult than flying in daylight, just different. I have yet to lose
orientation with NIGHT OPS!!! (which is a pretty big statement considering how recently I crashed during the day because of
misinterpretation of model orientation--pulled when I should have pushed ... oops.) At the Visalia Fall Fest I let numerous people
bungee launch my "NIGHT OPS" equipped DAW Me163 with no orientation problems. I also had a DAW
TG-3 (that Dave Sanders was kind enough to loan me, thanks Dave) lit up with "NIGHT OPS". I won't
mention his name without permission, but a very well known pilot was seen practicing his spot landings with the
NIGHT OPS TG-3. The fact that he used Dave Sanders' hat as his landing spot convinced Dave to place aforementioned hat on
the ground. This pilot has amazed me every time I've seen him fly, but spot landings in the dark with a very high landing scores
(90+) on most attempts?????
This system is very, VERY bright. Much, Much, Much brighter than cyalumes. At the
Banos Bash this last Sunday, the airplane illuminated the slope as it flew over. You could distinctly see the hill being illuminated
with the airplane at an altitude of 40 feet. "NIGHT OPS" is that bright. The airplane lit the slope well enough
to shoot low approaches and touch and goes. The brightness for the lamps is listed as 19 FL or 65CD/m^2. I wouldn't know a foot
lumen or a candela per meter squared if it walked up and asked to borrow a photon or two. The best way to describe how bright
NIGHT OPS lights are is this: In my darkened room, with the airplane resting on the ceiling fan I can read a newspaper by the
light of my "NIGHT OPS" airplane lamps. (I recommend turning the ceiling fan off prior to this experiment.)
I guarantee that brightness will not be a problem. If you FLY for 5000 hours and your lamps burn out, you've got too much spare
time and I am jealous, but I'll replace them free of charge.
I am very interested in any questions you may have, and can be reached by the methods
listed above. Thank you for taking the time to read what worked out to be a long post and I hope to see YOU during
NIGHT OPS.

More Notes on the Mid-America Flies
Although it is now a LONG time since the middle of July '97, I want all of the EFO and Ann Arbor Falcons to know just what a GREAT JOB they did, and how impressed everyone was with their PARTY! Yes, it's a party, a celebration of flight, and especially e-flight. Great job folks! :-)
Jim Bourke - Head honcho of the E-zone Magazine and maintainer of the eflight
list, "I just got back from the mid-America fly-in a couple of hours ago. I'm sorry that I missed Saturday because several of
the people I was hoping to see were not there on Sunday.
It was a great event. The weather cooperated wonderfully. I packed my Ministreak into a
small box and brought it with me, but I was only able to put in one flight due to a problem with the aileron servo. My FMA S-80
went out just after the first flight of the day. I was fortunate that it did not have any troubles in the air.
Clay Howe - "WOW! Another great Mid-Am weekend...I think that Keith mentioned
that this was the 11th Mid-Am, and although I have only attended the past four, it was the largest crowd that I have seen at the
event. I'm sure that Ken Myers will give us a full report, and I would expect to see that there were at least 75 registered pilots -
maybe more. (66 on Saturday, 63 on Sunday - 75 pilots and over 280 plus aircraft! km)
The field was quite nice and there was usually a slight wind almost straight down the
runway. Although the temperature was a little high - 80's to 90's - there was lots of shade available, and plenty of cool drinks to
keep everyone from drying out.
My plans were to do a little flying, and a lot of video... and I did get the Kadet up a few
times and a couple flights on my original SP400 sport plane.
Several people who have purchased my other e-flight tapes were at Mid-Am and asked
about the '97 tape... if all goes well, I'll have it done in a couple weeks." (It is! See how to order elsewhere in this issue.
km)
Louis Dionne - "Last's year Mid America (1996) was my first real R/C meet (and
electric as a bonus). It was a revelation to me. Yes there is more than just me, more than a handful us, more than just barely flying
around. This year was a real boost, an inspiration.
Here are some of the highlights from my perspective.
Doug Ingraham - "This was an exceptional year. I am still on a high from
attending.
Martin Irvine - "Laddie's little twin at Mid-Am was an Autoplane, (1930s
British). It spanned 62", weighed 3.5 lb. and had a pair of 6 volt Sp400 on the titanium gearboxes, (ratio unknown but likely
1.8:1). Props were a pair of Graupner Slim 8 X 4 and power was 8 X 1700SCRCs. He consistently exceeded 10 minutes per
flight. I hope he publishes the plans." (Me too! I was that close to awarding him the CD's Choice on Saturday - a
MOST impressive aircraft! km)
John McCullough - "I'm just about recovered from that wild weekend in
Michigan... Doug and I had a great time, as always. Spent way too much money on goodies at Kirk and Andy's tents though.
Plenny Bates - "Bob Livin, Jim Porter and I had a great time at the
Mid America. Bob is ready to return. I have not talked to Jim. Please pass the word on to Keith and the rest of the EFO and
Falcon members."
Tom Cimato - "Hi Keith, Thanks for having such a great and well executed meet. I
heard nothing but good comments! It was good seeing you too. I wish we could get together more often.
David Bailey - "Let me tell you what a great time I had at the
Mid-America this year. The variety of aircraft types was most impressive! The event was well organized and thoroughly
enjoyable. Great job!
Dear Ken and Keith:
Return to "What's In This Issue?"
Mid-America Video Reminder!!! from Clay Howe The '97 Mid-America video is great! This year the video is 1 hour and 53 minutes in length,
and is supplied on a T-120 VHS tape at SP speed. I believe that this one is even better than last year's. (It is!!! - km)
Great Planes PT Electric Rating
Plane: Great Plane's PT-Electric
Comments: This plane couldn't be better! Kit is very well done, well organized. Construction is easy. Fuse has
plenty of room for mounting any/all your stuff. Flies like a dream, like floating on a cloud. ROG very well, flies for 5-20
minutes. Draws favorable comments every time I fly it. Also made a second wing modified to include ailerons - flew great!
Don't know how this plane could be any better.

Dear Ken:
Jay Putt, 123 Lower Sheep Pasture Rd., Setauket, NY 11733, sent along the
following information about Gehard's fantastic plane. This plane was first shown at the November SEFLI meeting. Even though
Jay's photos show the plane very well, I have been told that it has to be seen to be believe. I had the pleasure of meeting Gehard
at the first e-Nats I attended, and I want to tell you that he is one of the very best craftsman I've ever had the pleasure to meet.
Here is the info, and thanks very much Jay!

Ralph's Bleriot is a kick! I hand launched it and just about out ran it
Marc Thomson's Spitfire and Canadair water bomber (when I grow up I want to be just
like him ! the car, the planes, the flying skill,... the wit, the smile)
I hope someday to be able to fly like him. He manages energy better than anyone I have
seen."
Thank Keith, Phil (that's me - we've got a "name thing" going km)
and the whole gang for another great meet. I really enjoy it more than KRC.
George (see - told you it was a name thing km)
P.S. I wasn't kidding about the Speed 400 AULD Combat........ It would be awesome!!!"
Please pass on my thanks to Ken and the other club members for being such good hosts.
It really was a pleasure being there."
Thanks and keep up the good work with the Web site and the Mid-America. Both are a
really great resource for budding electric fliers."

23 July 1997
Just a note to thank you both for directing a great meet this summer. I really enjoyed it
and got a lot of new ideas.I've seldom seen so many beautiful and innovative models.I know the kind of work that goes into
doing such an event and so you both need a hearty congratulations. Too, I am thankful to the Midwest R/C Soc. for the loan of
their fine field. I was all for their strict safety rule--all fields should have them.
The B-17 had an unscheduled landing. After a perfect take-off and flight I put the gear
down and set up for landing. Then it happened .The plane turned away from me, climbed to about 200 feet (I had no control)
started a spiral dive and went in. The spin to earth was, at least, very realistic. I guess the formula F=MA really works. 9.5 lb.
models at 55+mph into a bean field--well I may rebuild this winter. Meanwhile the Amiot 143 battles on - Vive La
France.
Again thanks a lot.Keep your airspeed up and have a great rest of the summer.
I did miss a couple shots that I wish that I had got, but it just happened as my camera
decided to "go south". This problem was quickly corrected with the help of Tim McDonough and Ed Koffeman...

Rating: *****
Motor was the supplied Goldfire 05, direct drive, 8x4 prop. Batteries 7x1400.
Radio/servos JR 4 channel, rudder, elevator, speed control (AstroFlight 217), and (with the second wing I built, using one
Hitec micro servo) aileron.
Futaba Rx with 500mAh pack and 2 micro servos. 550 Goldfire motor on a 6 cell pack, 8-4
prop (motor and prop are supplied with the kit), AF217 ESC. My first plane. Didn't climb well, but flew very well. Major
shortcomings were low climb rate and three channel operation (easier to learn but I outgrew it after a season).
FMA micro Rx on a 270mAh pack, 3 HS-80's, AF210 ESC. AF cobalt 15 direct on 10
cells. Flies well, does nice aerobatics but I think the direct drive motor is not all that well matched to the relatively draggy airframe.
Makes a good second plane though (aerobatic but still pretty stable).
FMA micro Rx, 2 HS-101's, M-15 ESC/BEC. Robbe 400/45 (aka sp400 7.2V) on 8 cells.
Very nice sport aerobatics. Good speed, tracks really nicely, and good low speed handling. Good match between the plane and the
motor. Plans only but builds really fast (it's a "stik" design).

The Sprite-20 is a 20 amp continuous, micro processor based electronic speed controller
with BEC and brake for six to eight (or ten with micro servos) cells. It weighs less than 1/2 ounce (WITH wires), and measures
only .9" x .6", and retails for $54.95 ... Kirk Massey (New Creations)
and Sal DeFrancesco (National Sailplane Products) will all be carrying it. Kirk and Sal have seen beta version, and are quite impressed. You might have heard about it
from one of my beta testers, Alex Mishkovsky, Richard Sutherland, Michael Daniell, John Bell, or one of the many others.
This is my first foray into marketing and selling a model product. I spent about four months
designing, programming and laying out the Sprite. It was fun!
I hope everyone saw the new Simple 400 photograph in the August 97, Model
Aviation, page 25. The model was designed for direct drive speed 400 motors but can be flown with gas or as a slope
soarer. Plans show rubber, elevator, and aileron control for aerobatics. It could be raced as a one design racer. The
Simple 400 uses the Ace RC tapered foam wing at full span of 35". Flying weight of prototypes was 17 oz. with
three HS60 servos. It flies fast and with authority. It is fun with the rudder servo for snaps, spins and hammerheads, etc. The kit
will be low cost and should be out by Christmas, probably sooner.
I will find or take a picture of the Simple 400 for you and the Ampeer. We
appreciate the plug. The Simple 400 is a fun little ship that builds fast and should be cheap. I designed the airplane after seeing
all of the cute but expensive models at the trade show. My goal was a $25 kit, but we will have to wait to see how it is priced.

These are pictures of the first prototypes. Kit shows electric (featured), gas and
slope glider. Photo in Model Aviation is of later production version with a smoother front end. Kit is an extension of the Simple
Series models using the Ace RC 35" foam wings. At the same time a Simple Corsair and Simple Cub will also be released.
Although not shown on the plans, these other models can be flown electric with an AP29 or Speed 480 sized motor. I sent all of
my pictures of the Cub and Corsair to Ace, at least I couldn't find any to send you.
Thanks for the plug! Ace RC is alive and well and will emerge after the
regrouping, stronger than ever. From the outside, right now it seems like nothing is happening, and it may take a couple of months
to see progress, but it is happening. There are several new kits planned and are ready to go. As it stands now, I will continue to be
the major designer. I love it.

Just finished up the tach in the September issue. It works, sort-of. It was a fun
project but will be a pain in the field and the increase in resolution isn't all that great. For someone that would like to have a tach
for home testing but not enough to spring for one of the low end jobs, it could be useful and it is cheap. Especially if
you replace the $8 Lithium cell with a couple of alkaline pen cells.

P.S. How many days till Mid-America????????
I see from your October 1997 issue of the Ampeer that someone in
July requested info on canards and flying wings. I have a few articles on canards. They are not electric however the information
provided can be used for a electric version. So if the individual is still looking and/or interested in Canard information the following
may help:
TO ALL ELECTRIC FLYERS EVERYWHERE
The Silent Electric Flyers Of San Diego proudly announce THE SAN
DIEGO WINTER ELECTRICS -- February 13-14-15 1998.
A first ever fun-fly for snowbirds and escapees from winter's rigors. The meet
will be held on the shores of Mission Bay next to SEA WORLD and a mile from our famous San Diego ZOO and AEROSPACE
MUSEUM. We invite all builders and AMA flyers of electric aircraft to show us their best at a location just a mile from where
Charles Lindbergh first lifted the SPIRIT OF ST. LOUIS into sky.
Details on this exciting meet can be found at our website
http://www.sefsd.org A full schedule of activities is planned during daylights plus a tour of
the museum and a banquet featuring as speaker, "ASTROBOB" BOUCHER, will be held in the evening.
Equipment manufacturers and vendors are invited to display their latest
achievements. For details, e-address- info@sefsd.org
Back at the '96 E-Nats a couple of fellows from the east coast showed up and
took home 11 trophies and plaques between them. These outstanding modelers are Mr. Bob Aberle and Mr. Tom Hunt!
Outstanding modellers and fliers and mighty fine folks, too!
Again in '97 they returned and Tom Hunt racked up enough points to win
both the NEAC and AMA Champion Awards! A truly great achievement! Somehow, through a series
of omissions and errors, this great feat has not been mentioned correctly in the national modelling press!
To help congratulate him on this outstanding achievement, and to let him know
how proud of him we are, it would be a good idea to drop him a note of congratulations, as we are doing. We, the EFO, are very
happy to send our congratulations, and we hope that you will join us.
You can send U.S. mail to:
Tom Hunt, P.O. Box 1467, Lake Grove, N.Y. 11755-0898 --- Phone/FAX: 516-981-0372
or e-mail at THunt95147@aol.com
It was certainly a surprise and pleasure to be the winner of the Futaba
radio at your recent event. With all of my projects, many of which are electric, it will come to good use.
Please also accept my heartfelt thanks for putting on such a wonderful Electric
Event. I only wish I could have been there for both days and stayed longer on Sunday. Next year!
Thanks also go to the many flyers, you Keith in particular, that helped guide me
and solve the problems I was having with my Electric Hots. I'm pleased to say it continues to fly very impressively.
Keep up the great work promoting electric flight!
Sincerely,

WING AREA 168 SQ. IN.
WEIGHT 18 OZ.
WING LOADING 15.5 OZ./SQ. FT.
CHANNELS 3
INTRODUCTORY PRICE: $75
The Hellcat Speed 400 is a moderately easy to build warbird that's sure to stand
out in a crowd. Designed specifically for inexpensive Speed 400 electric motors. With the new AstroFlight 020
brushless motor, performance is sure to be spectacular.
This is a complete kit, with all shaped parts laser-cut for perfect accuracy. High
quality Sig balsa is used throughout. Fuselage construction is conventional balsa, and the wing is tough but lightweight sheeted
foam. All-up weight is 17 to 19 ounces.
For best performance, I recommend the following flight hardware:

INTRODUCTORY PRICE: $75
The P-38 Speed 400 is an easy to build warbird that makes an ideal first twin.
Designed specifically for a pair of Speed 400 motors. At 12th scale, it's the right size for the popular AMA 704 scale combat
event, and it will just fit under the 2.5 pound maximum weight limit. Top speed as designed is 50 mph.
The model is based on the semi-kit concept, which optimizes value by including
only the laser-cut wood, foam wing cores, canopy and decals. The builder supplies such items as the wing skins, nose block, and
triangle stock. Not only does this keep the kit cost down, but it allows the builder to hand-select the balsa stock for minimum
weight. We recommend 6 to 8 pound stock for best results. The builder also supplies the minimal hardware like hinges, control
horns and pushrods.
For best performance, we recommend the following flight hardware: 7.2 V
Speed 400 motors, Graupner 1 3/16" racing spinners, Graupner 6 X 4 props, 16 X 600AE battery
pack, Viper Model Products Micro Demon 100 speed controller and micro radio gear.

I wish to thank you for having me in the Email loop. I get that where you're at
it's cold or that the wet season has arrived. Well in good old northern California, San Francisco, we're at high 70's, no clouds, and 2
to 5 mph winds all day. Very, very nice.....
I have something for you and the rest of the E-modelers. This information is
about brand- new nicads of the "SCR7quot; type (They are Panasonic. km). They are surplus nicads.
Ten 1300 mAh cells which charge up to 1500 to 1600 mAh, for $5.00. Yes five bucks in lots of one pack of 10 cells! Ten cells for five dollars. The prices for more are; 5 ten cell packs for $22.00 , 20 ten cell packs for $75.00 or 100 ten cell packs for $250.00
The outfit is ELECTRONIC GOLDMINE IN ARIZONA: 1-800-445-0697 or
(602) 661-8259
These nicads are on their flier, part #GB517. I bought 30 packs, I can give you a
pack if you wish. You can show it at your club meeting. (Thank you so much. I did show them at the November meeting,
and several folks took down the address. km) The batteries have to be reworked for motor packs. Remove the
spot-welded inner connections with pliers and file the battery ends lightly, to remove spot-welds. Removing all the cells from the
pack, removing connections and removing old spot welds with a file. It takes about 10 to 15 minutes.
These guys also have fast charge 700 to 800 mAh AA's in four pack for $20.00
for 10 four packs. Good for Tx , Rx and Speed 400 packs.( These are new cells also , part# GB498 ).

MaxCim Motors announces the release of a significant upgrade and
improvement to our Brushless DC motors and Digital Speed Controllers for the R/C enthusiast.
The specification details are now on our website:
http://www.maxcim.com
The MaxNEO-13D and MaxNEO-13Y motors feature hi-flux Neodymium
magnets which provide an increase in Kt (torque constant) and Km (motor constant) - meaning that we've increased the power
density.
The more significant change is that they have greatly improved coil windings and
larger diameter lead wires resulting in a nearly 40% reduction in the Rm (resistance at the connectors).
This translates directly into more prop rpm and an even cooler running system,
along with the ability to handle higher currents and cell counts.
We've also improved our 100% Digital Speed Speed Controller with software
and hardware changes that make it even more user friendly. We've increased the part throttle efficiency a bit more, increased the
PWM frequency and increased the (already good) reliability of the FET drive circuitry while reducing on board parts count which
further enhances the reliability. (less parts to fail).
We've moved the status LED to the battery end of the unit and added a set of
pins for a remote LED, optional cabled LED assembly, that can be mounted in a convenient spot in the model. Along with this
we've added a number of diagnostic functions to the software to assist in diagnosing and troubleshooting. (Many radio problems
have been solved by the use of our processor codes!)
An especially exciting addition to our software is the ability to reverse rotation of
the motor (and with our "Auto-Phase-Advance" - no need to change the motor timing!)- from the transmitter! Imagine
the aerobatics you could do if you could spin the prop in reverse on command! (Scares me to even think about it
MaxCim Motors will continue to improve its products to provide the R/C
modeller with the best brushless power systems available.
Hoping to provide your electric power needs in the future, Tom
We're planning on having some night flying Saturday
evening. There will be food available most of the day, we'll probably try to hold
a dinner towards evening. More details will follow. For more information contact:
