Puddlemaster Plane Rating
From: Paul Combs email: pmcerc@netzero.com
Ken,
Attached is a picture of my "Puddlemeister" - it's a slightly modified
Ace Puddlemaster. Deviations from the standard kit: 2.5:1 geared Trinity Sapphire car motor turning an APC 9x6E, modified
vertical fin / rudder.
It flies OK with 7 2400 mAh cells, but flies best with 7 1250 mAh SCR's (much
lighter). The picture is with the original wing - it is now flying with the wing from my Goldberg Mirage. The high thrust line
takes a little getting used to, and it's just a bit twitchy, so I don't make any last second changes on the landing approach or I’d be going for a swim. Don’t forget to save
a little juice to taxi back to shore with (it handles great on the water).
This plane is loads of fun to fly off of local ponds - lake flights are nice too but only
when the wind and water are very calm.
The next step is a wing with ailerons to increase the fun. The kit was so-so, but
because it's such a kick to fly I give this plane 4 stars.

Wooden Zagi
From: Tim Knowles DTKNOWLES@aol.com
Just finished reading the latest Ampeer, Great newletter/web page etc. good work
thanks. I always read it and I appreciate the E-mail notice.
FYI on the Wooden Zagi, my flying buddy Joe Colletti has built a plane that he calls
a ZagStik. He used Tom Hunt's stick building technique and the Zagi planform
www.ezonemag.com/articles/2001/jun/gallery/gallery.htm
Pictures of Joe and the Zagstik are in the above link.
The inspiration is derived from the fact that we both have Zagi 400's and we both
built Elipstik's, Joe's from Tom's kit and mine from the plans.
Joe did reduce the wing area a little but the ready to fly Zagstik with speed 400
motor and 8 each 600AE cells is 14 ounces (the gallery article says it weighs 17 ounces but we weighed it yesterday and got 14
ounces). It is much more dynamic than the Zagi 400, faster and the rolls are very axial.
Keep up the good work.

P-63
From: Weldon Smith email: lasfws@mc.net
This is a photo of my P-63, my favorite plane in 40 years of flying. It has following
features: 72" span, direct drive Astro 60 with extension shaft because of long nose, 25 cells driving 16-8 prop, 29 amps
static, retracts, 10 pounds, 28 oz. wing loading. It was finished last year, but has not SUCCESSFULLY flown yet. I'm still trying
to find a satisfactory field. Expected to fly it in the fall.

RF Interference Problems
A problem that occasionally pops up with electrics is radio frequency
interference. Many Ampeer readers have been kind enough to share information on this topic with Bob Mugge, who
was having problems with his B-17 project. I’m happy to report that Bob’s problem seems to have been solved. Here is
some more information that just might be helpful to other. KM
Subj: B-17 saga (interferences)
From: Paulo Faustino rdd53650@mail.telepac.pt
Hello Ken,
I've enjoyed very much your newsletter and appreciated your work to develop
electric flight.
About the subject, I read carefully the story from Bob Mugge and let me give my
own experience:
When I was using the F115 and F116 Futaba receiver's on my electric planes and
sailplanes I had the same problems that Bob is having. When I changed to the F138DP and F148DP receiver's (much more
expensive), I had all problems with interference solved, but a new problem arose: these receivers are much too expensive and I
have other planes to fly and didn’t want to change the receivers from plane to plane. Solution, (it works for me and others of my
club), is the use of the Pico 4/5 from Multiplex with a crystal from the same brand and the Hitec normal 5 channel receiver (they
now have an dual conversion version of it) for all my planes.
Let me describe them:
Graupner Cumulus 2000, Speed 480 3,45/1; 7 cells, Receiver Pico Mpx
FVK Silent Dream 2,5m; Speed 600 2,8/1, 7 or 8 cells, Receiver Hitec
Kyosho Zero and P-51 (foam) 1m, Speed 500, 2,9/1; 8 cells, Receiver Hitec
Kyosho Cessna 177 1,2m; Speed 500 3/1, 7 or 8 cells, Receiver Hitec
Kyosho Flash 1,2m; Speed 500 2,9/1; 8 cells, Receiver Pico Mpx
Kyosho Valencia 1,78m; Speed 500, 3/1, 8 cells, Receiver Hitec
Kyosho Express M29, 1,65m; AP 29, 2,33/1; 7 cells, Receiver Pico Mpx
Kyosho T-33 1,17m; AP 29L, Fan, 7 cells, Receiver Hitec
I test my planes and sailplanes by this way: I collapse the transmitter antenna of my
Futaba FF8, and walk away by 25 passes or, let's say, 25 metres. A friend holds the plane at waist height and all functions are
tested. If all works right then, I can fly for sure, as I think that the range is good.
I hope this very long e-mail can help.

B-17 Motors
From: Keith D. Shaw
The King Crimson used the hot-wind gold label Leisure 05s with the long nose 3:1
gearboxes. Three .01 DISK capacitors, make sure to use the cheap disk caps, they have much better high frequency response
than Mylar, PS, or tantalum. I also had a 10 amp 50 volt Shottky diode across each motor (anode "hat" to positive) to
help control current spikes. Try to have a one turn per inch twist to all the power wiring, this will help keep the radiation noise
under control. Keep all the R/C wiring as far away from the power wiring. If you are using separate aileron or flap servos, the
wiring should be in a separate channel more in the rear of the wing. You might want to try a ground range test with the flap and
aileron servos unplugged at the receiver end. I had a twin years ago that drove me crazy with noise fits. It turned out to be the
noise was being induced into the aileron leads, and pipelined to the receiver. I relocated the servo wiring and used a servo buffer
amp, that solved the problem.
The King Crimson flew with the Leisure motors for 12 years of hard airshow use,
but finally the motors had just faded too far, rebuilds just didn't do it anymore. I converted it to Astro FAI 035s, so now have
about twice the available power. I used the same three .01 disks and10 amp Shottky diodes. The range is still fine even though
the full power current is 30+ amps. Leisure motors hold up fine in the 20-25 amp max range, but don't go over that as they will
degrade very quickly.
Good luck,
Keith

Ferrite Motors and Gearboxes
From: Paulo Faustino rdd53650@mail.telepac.pt
Hello Ken,
I just completed the tests on my own imitation of the Team Gear 40. It’s a
homemade gearbox using two 13 Turn Yokomo motors and spur gears from an R/C Car.
The two motors were bought from a shop that can’t sell them at the initial high
price, as they are out of fashion, although they are only 3 years old.
I put them in series with 16 cells, the spur gear is an 80 tooth 48DP and the pinions
17 tooth. This gives a relation of 4.7:1. Turning a Graupner Grey 12x7 propeller, I get 8000 RPM at 22 amperes. Talk about
power: this is the kind of power an O.S. 53 four-stroke would provide: around 8000 to 9000 RPM on an 12x6 propeller.
I intend to use pinions of 15 teeth to get a relationship of 5.33:1 and use a 12x10
Graupner aerobat series propeller. That will get about the same amp consumption and could be put in a Kyosho Spacewalker
along the same way as the gas version at only 3250 grams or less, if I use micro servos on him.
The great thing about all of that: it cost me less than 68 dollars to get it.
What you think about it. (Sounds great! KM)
Happy landings.

UNI-Dome Indoor Flying Dates
From: Bobs R/C bobsrc@forbin.net
Hello all indoor flyers, R/C and FF,
For the last two years the Black Hawk R/C Pilots and Bob's R/C Hobby Supply
have been able to obtain the use of the University of Northern Iowa's UNI-Dome indoor football stadium to fly in. This is on the
University campus in Cedar Falls, Iowa which is in N.E. Iowa and about 3 miles north of Interstate 20. There are 3 dates
as follows;
Sunday, October 28, 2001. 7 a.m. to 3:30 p.m.. Astro turf football field with no obstructions
Sunday, December 9, 2001 8 a.m. to 6 p.m. Basketball floor down but bleachers and curtains removed and speakers up( The floor is being refinished, so the bb goals should also be down)
Sunday, January 6, 2001 8 am to 6 p.m. same as above
We have been flying free flight at one end of the stadium and R/C at the other and it
has worked well for us. We are not sanctioning this as a contest and do not intend to run any events ourselves, but if any special
interest groups wish to run events we will try to accommodate them. Please contact Bob Nelson to get on the schedule. We are
also inviting any industry people to display at this event.
I realize that this is pretty short notice, but we have to wait for the University to set
their schedule first and then take the open days to get an affordable rent. For more info, e-mail bobsrc@forbin.net, use our U.S.
Postal Service address or call Bob at 319-277-0211 days or 319-233-4771 evenings. Please pass the word along ASAP as we
have limited time to advertise.
See you all there for a day of fun!

Two Old Timers
From: Armand Francoeur afran@mediaone.net
Ken,
I have attached a picture of a restored and electrified Q-Tee. It was originally built
and flown with an .049 glow engine in 1976 by a friend. I thought it would be appropriate to compare it to the new Cutie that you
just reviewed. It uses an Speed 400 with a Mini Olympus gear and a 9X5 prop. I use an 8 x 700 mAh. pack and get 6-8 minute
spirited flights. The original builder says it flies at least as good as it did with the .049!
I have also attached a picture of a restored and electrified Jr. Falcon which was also
built in 1976 by the same friend. It has the same power system as the Q-Tee and is a great flyer.
These were great little "park flyers" in their day and are still fun to fly
today with e-power.
Regards,
Armand Francoeur

The Twins
From: Walter Thyng docwt@worldpath.net
Hi Ken,
Here are the photos I promised you. I've never tried this before, so let me know
how it works. (Just fine! KM)
This is my Graupner Comet. Powered by two 480BBs pushing the Graupner
Impeller units. Battery was a nine cell 2000 mAh NiCd. Esc was a Jeti 50. Ailerons used two TS-11 servos. Elevator and
rudder, S-100s. Control was via my new Airtronics RD 6000 Super. I did add a rudder and changed the elevator so the servo
pulled for up, but otherwise built (assembled) it per instructions. C/G was right on in spite of the rudder servo. One of the photos
shows the inlet holes for cooling air. I left the fuse open under the rudder for exit.
My PVC pedal launcher tossed the Comet into the air with authority and after a
slight sag, speed built up and the Comet was smoking. It was also a handful as I did not have enough elevator, even with dual
rate at 150%. I also experienced a problem using the digital trims on the RD 6000. You can't just pull the lever down for full
trim. You have to wait for what seems like an eternity, until the beeping stops. I finally got it under control when it suddenly
started down. I pulled the throttle back and leveled the wings. It hit almost flat, but the impellers caught something and took the
wing off as well as destroying the fan units.
I really think this would have been a great jet, but I'm between positions right now
and couldn't afford another $140.00 for new impellers (Graupner's term). However, I do have an unused pair of Kyosho 580s. I
will send you photos of the converted "P-Comet" if it flies.
My Sportwin is built from S&EM plans. Again, I added a rudder. Power is two
6v Speed 400s, the ESC is another Jeti, Servos are HiTech 85s, props are CAM 5.5 x 5.5. Battery is eight zapped 800s. Rx is
an MPI. Weight was 1/2 oz over plans. WOW! Does this thing GO! Even our club speed freak was bowled over. It flew
straight off the board. Ailerons were very slow at the recommended settings. I have since doubled the throw. I didn't check
flight duration, because whatever it is, it's long enough! This thing is almost as fast as my hopped up F-16.
Landings are a delight. When the Sportwin stalls, it just bobs up and down. Lower
the nose and you're flying again.
When this designer's P51 hits the Mags, I'm going to be as close to first in line as I
can (Come to think of it, his new ME-262 design might make a nice home for those two 480BBs).
The last photo speaks for itself.
I would rate the Sportwin as high as I can without using up my one 5 star rating.

Wing Loading: 15.8 oz/sq.ft. (48g/dm2)
Requires: 3-channel radio w/2 standard servos, charger
SuperStars have long been the most 'modeler-friendly' trainers in the industry -
known for their top-notch materials, incredible ease of assembly, and slow, smooth, confidence-building flight characteristics.
Hobbico now unveils a new Almost-Ready-to-Fly SuperStar with all of these same features, and equipped with a powerful
electric motor instead of a glow engine. Let the SuperStar name draw your customers to the SuperStar EP ARF - where they'll
be sold on the benefits of clean, quiet, easy and affordable electric power!
- The SuperStar EP ARF uses only high-quality wood components, and comes pre-covered in a durable plastic film.
- In addition to a high-performance ElectriFly T-601 motor and propeller, an electronic speed control is also included.
- A video is also supplied that shows modelers the final assembly steps, at-the-field flight preparation, and instructions on how
to operate the radio.
Here are some of the advantages of electric power:
- No fuel mess
- Lighter weight and slightly smaller size - easier to transport
- Less noise - especially important at airfields with noise restrictions
- No large amount of field equipment to buy, carry or store - more convenient and economical for the beginner
- Easier and simpler pre-flight preparations - just charge the battery and hand-launch or runway-launch!
A flat-bottom airfoil supplies excellent lift at slow speeds, and also helps keep the
model level. As a result, the SuperStar EP ARF is very stable and easy to fly - making it an ideal trainer choice for beginners!
Right out of the box, the SuperStar EP ARF is already mostly assembled. In just 3-5 hours modelers can have it ready for their
first flight. The roomy radio compartment allows for easy installation of all on-board electronics.

Scott Rellinger’s Herr P-51
Scott and I started this project early in 2001. It is not a
difficult project at all, but both of us had a 2001 with lots of other obligations. Many folks have converted various
Herr kits with Speed 400 motors, but this 302 sq.in. model of a fighter, screamed for fighter like performance. I worked out the
math and came up with an Astro Flight 15 direct drive with 9 1.5 ounce cells like the 1250SCR, CP-1700 or the 2000 NiMH
cells. This should give fighter-like performance in a trim package. Craig Moeller provided the graphics for this Rockwell
version.
Saturday, November 10, was not a day to test fly, but since we had already agreed to meet at the field, and the pack was charged, Scott, being pilot in command, decided to fly. Winds were 20+ MPH (NO, NOT just saying that - honestly 20+ MPH with gusts over 25 MPH) but right down the runway.
The other fliers had already packed up. The majority of things had been checked out before hand, so with a small preflight check, the P-51 took to the air. Scott applied the power slowly, the tail lifted and off she went. It was rock solid through the whole flight. Scott was so excited that he had to do it again!
Scott is an excellent glow flier and heli pilot, and now he can rightfully call himself an accomplished electric pilot.
The plane flew with no trim changes. (Yeah, Yeah - I know, no plane does - but it really did.) It was absolutely amazing the way it handled the wind. Here are the important specs: Herr P-51 42-inch span, 303 sq.in., 40 ounces, wing loading 19 oz./sq.ft, motor: AF15 direct, cells: 9 Sanyo 1250, ESC AF215D, JR radio - I'm not sure on the servos, but they aren't "minis", but are small, 8x6 Rev-up Prop.
While the flight time is nice, the next pack will be 2000 mAh NiMH cells. I have to admit that I thought him a bit foolhardy taking off in such a wind, but what a beautiful flying machine, with no bad faults and great aerobatic potential. He did rolls, loops (inside and out) stall turns and more. It turned out to be a wonderful day for a test flight.

Keith Shaw’s little twin isn’t new-in fact, it’s about 20 years old! But with new
ESC, it flies like most of Keith’s planes-great. When I asked Keith about it, he wrote:
"It is my ancient Aerocommander Shrike in Bob Hoover markings. It was
built in 1978(?) originally powered with two Astro ferrite 02s, identical to today's speed 400 except they were wound for 4 cells,
motors wired in parallel.
"After a while I flew it with 5 cells for a little more zip, but the motors
needed rebuilding about every 15 flights. It then was modified to the "new" Astro 035 ferrites, a longer version of the 02
designed for 6 cells. These motors flew it even better and needed little maintenance.
"It was severely damaged at an early KRC (~1984) when someone turned
on during a low pass. The front of the fuselage back to the wing and both nacelles were totaled, and the motors were damaged.
It sat in limbo for a couple of years until Astro Bob brought out the Cobalt 02, a shortened 05 designed to run on 4 cells. I
completely stripped the plane down, built new nacelles to fit the c02s and a new front fuselage. The motors were run in series on
8 x 900SCR cells, and a "interesting" wiring scheme was used to give me off, two motors running or only the right motor so I
could do Hoover's one-engine-out routine.
"It flew many air shows, I used it as my first flight warm-up plane. I
stopped taking it to air shows a few years ago simply because I ran out of room.
"A couple of weeks ago I decided to remove the mechanical switch system
and just have a BEC Astro speed control. It is now several ounces lighter, and has better power due to the ESC and shorter
wires rather than the lossy 4PDT and extensive wiring to do the off/one/two motors.
"It did take me a while to get some interference problems licked due to
motor noise piping into the receiver. Upon opening up the hatches on the nacelles, I found that I only had one cap across the
brushes, and it was the "wrong" type! Replacing it with three .01 ceramic discs took care of all the interference
problems.
"It was enjoyable to fly an old friend with new "life", even in the
gusty conditions Wednesday.
"As far as specs (from memory): Span: 42" Area: 260 sq.in.
Weight: 41 oz. Power: two Astro Cobalt 02s, 8 x 900SCR, Astro 215D, MasterAirScrew 5.5/4.5
props @12K, 14 amps."

Cirrus Receiver
From: Merle Davies mp_davies@yahoo.com
I forward these messages for your reading and reply. Perhaps any detailed
description could be inserted into a issue of "La Ampeer" Newsletter for general information to the many.
Merle
(Merle’s letter to Global follows. KM)
Dear Global Hobby Service,
I recently purchased a "Cirrus MRX - 4" Micro Receiver at a indoor
fun fly, for use in my new "Wingo" under construction. The instructions mention "compatible POSITIVE shift
system for Transmitters JR ; Airtronics ; Multiplex ; and Sanwa. Shift to NEGATIVE for Futaba and Hitec."
Where do I find the SHIFTER, and how is it moved? Please explain modes of
POSITIVE/NEGATIVE?
My assigned Radio is a "Cannon 3 Channel FM System", with Futaba/Hitec as
alternative.
What type is the Cannon POSITIVE/NEGATIVE?
Why must I use a Hitec Channel # 15 Crystal in this Receiver?
Will your receiver be compatible with ALL Electronic Speed Controls with BEC?
Thank you for your assistance.
Merle Davies
(Global’s Reply)
Dear Mr. Davies:
Received 24 October 2001
We sell the receiver in each mode, POSITIVE or NEGATIVE. You buy the one
necessary for the shift of your radio. There is no physical "SHIFTER". You state your Transmitter Radio is a Futaba
or Hitec, so it is a NEGATIVE shift, as above. I do not know what the "shift" really means, other than it is the method by which
the radio transmits a signal.
You must use a Hitec AM/FM single conversion crystal because the "Cirrus
MX - 4 Receiver" uses Hitec components. You match the frequency number (such as your Channel # 15) of your
transmitter.
Hope that helps.
Customer Service
(Merle’s added PS)
P.S. Nothing was mentioned about Cannon R/C Systems being POSITIVE or NEGATIVE shift. I will contact John
Cannon for that information.
Hereafter the builder must know his "shifts" before mixing different
manufacture of R/C Transmitter and Receiver components.
(Ken’s Comments)
This has always been true. For the most part, most receiver manufacturers
do not mention shift, they just say Futaba/Hitec or JR/Airtronics. Those have been the most prevalent systems in the US.
While not "commonly" known, many people in the US know that Airtronics products are Sanwa, and so were
the old Cox systems. Multiplex is a fairly recent addition to the US market, so for many this is useful information.
Yes, your speed controls will work with any type of receiver.

Kadet Solution
From: Mark Stringer ratby@bizonline.co.uk
Ken,
I noted the problem with the Sig Kadet model and getting it to fly on electric.
My new Team Gear Single unit may have helped here.
A high power Sport single running on 8 cells and turning a 11x6 standard Master
Airscrew might have been the answer. The unit is not small, but that is usually OK on a trainer. It does give more of a punch
and can handle more power through its gears than the average plastic or belt drive gear box and should give a good 8 minute
flight. It should have enough "grunt" to get the thing off the grass without throwing it.
Details of the two new Team Gear Single units are on my web site at
www.bizonline.co.uk/ratbyaeroplanes.
These have been developed to cover almost all sizes of model, except the really
little stuff of course!
