New E-club in Calgary Area
From: Craig climber@home.com

A few of us electric fliers in Calgary have decided to try and organize an all-electric airplane club. We plan to meet once per month (barring holiday seasons) and, basically, hang around and talk electric airplanes plus have the occasional seminar and show-n-tell. We have no field or dues and plan to keep it informal. We have a basic "starter" web page: www.members.home.net/eflier.
Once we have a meeting I am sure more interesting stuff will appear in it. Interested parties are invited to surf the web page and contact me (or Bruce) for meeting information.

Kyosho F-16
(I got this info from Steve Horney, via the E-zone eflight list. Visit the E-zone at www.ezonemag.com and join the eflight list. This is a press release from Great Planes. Initial flight reports from the field are excellent. KM)

Great Planes announces the new Kyosho F-16:

A new easy-building ducted fan EP jet.
The second in a series of electric-powered, ducted fan aircraft is Kyosho's sport/scale model of the General Dynamics F-16 Fighting Falcon. It combines the looks and excitement of ducted fan flight with the ease and economy of largely pre-assembled foam parts and electric power. Unlike most glow-engine jet kits, this F-16 can be easily built and flown by any pilot with some ARF experience!
* The tough, lightweight styrene foam fuse and wings are virtually pre-built and coated with a plastic covering that adds durability and style
* Includes a LeMans AP29L motor AND a ducted fan unit for concentrated thrust
* Requires only a handlaunch, and delivers smooth stable flight with its light wing loadings and a Clark Y airfoil
* Captures the sleek profile of the full-size F-16, complete with wingtip-mounted missiles
(Note: Model should not be flown with missiles attached.)
The inclusion of the power train make the F-16 a real value! The ball bearing-equipped motor works with the efficient ducted fan unit to produce maximum thrust. They're both also available separately for scratch-built jet designs, too.
Special side intakes combine with the lower scoop to deliver lots of power-producing air for thrilling jet flight.
A styrene foam stand is included that securely holds the plane while attaching the wings and performing other maintenance.

Specifications
* Wingspan: 36.8 in (935 mm)
* Wing Area: 302 sq in (19.5 sq dm)
* Fuselage Length: 35.4 in (900 mm)
* Approx. Weight: 2.5 lb (1150 g)
* Includes: LeMans AP29L motor, ducted fan unit
* Requires: 4-channel radio w/4 micro servos, speed control w/min. 30A capacity, 8.4V Rx NiCd battery, charger

Wingo Note from Greece
From: John Konstantakatos remek@ath.forthnet.gr

Dear Ken,
I didn't do sd much flying during my vacation as planned. The reason was that during the second week I had a sun attack (feeling exhausted with fever etc.)
I flew the Wingo several times before this. Even in the hands of a complete novice, who was diving the model, I didn't experience any of the self-diving behavior that was written somewhere. (Here - by Tom Hunt via Silents Please KM)
I have to say that the Wingo kit although looking all right as a beginner's plane, has many things to be cured by an experienced modeler before flying. One is the wing's saddle. Its so small compared to the chord, that the wing will rock to different incidence depending on the pressure and thrust. Maybe this is the reason for the diving habits and not the bending boom.
Regards, John
Thanks John. It is always a pleasure hearing from you and sharing your experiences in Greece. Hope you are feeling better now. KM

Plane Review, Flying Wing
From: Grant Calkins CasinoOp@thegrid.net

Here is another plane review on a cousin of the HobbyFlite 747 I reviewed last month. The owner of HobbyFlite, Chris Hill, has created a new plane product by attaching the two 747 wings together (with suitable dihedral trimming) and the two 747 stabs for vertical fins to make a flying wing. It flies super! This saves new molds (the 747 molds were very expensive), which allows him to sell this plane including motor, prop, and all control surfaces attached, for only $65 retail! Tony Frackowiak, our "pro" maiden-flight pilot at Edwards AFB took a try with mine recently and bought one on the spot!

Here is the review:

The rubberized styrofoam Boeing 747 by HobbyFlite, reviewed in the September Ampeer, has led directly to a new and unique plane, a 48" WS flying wing, and does it fly! Stable and true, this plane ROGs, loops and rolls, hand launches, and flat spins - all for $65 retail including Speed 400 6v pusher motor, props and landing gear! And the darn thing is just about indestructible. Clear lexan elevon control surfaces are already mounted with control horns attached, you add two micro servos, Rx, flight battery, and ESC. I used an 8x500 mAh pack and Pixie 14 ESC, and it flies for nearly 10 minutes. Mount all the parts by simple carving out recesses in the underside of the wing(s) with a soldering iron or razor blade, then clear taping over them. Then go out and fly - and fly it does! A solid 4 1/2 stars (****1/2). Contact HobbyFlite on the web at www.hobbyflite.com or by phone at (805)490-8681 or order through New Creations.

BOB LIVIN'S FORD TRIMOTOR
From: Plenny Bates plennyb@comic.net

Bob with plane in tow Front left view

It does fly. Bob got the third flight in today. Gusts to 16 but still in one piece.
As you may know he did not bring it to Ann Arbor because the outboard motors made so much "noise" the radio range was about 8 feet. While at your event he talked to Doug Ingram who suggested checking the commutators and resetting the timing of the Astro G 05's. Bob turned the commutators and retimed the motors and the problem was gone. The center motor is an Aveox F27 light on 16 cells and the 05's are in series on 16 cells. The plane carries 32 cells. Weight about 16+ pounds - maybe up to 17 pounds now.

The SR Batteries X250

While at Toledo this year, I spent some time with Mr. SR, Larry Sribnick, and kept picking up and examining X250 prototype that was on display. I must say that I was very impressed. Larry finally released the kit in September. As many of you readers know, I’ve had a problem with S400 models - I can’t see the little bliters!!! Watching me fly my Rocket into the ground coming out of a sunset has become a pleasant pastime at the local flying field. Well this one is the same size as my Lightening E250, so that solves that problem. Another problem I have is building someone else’s model. I always want to make modifications. This one sure doesn’t look like it needs any.
I plan to order one ASAP and build it stock and report here about it. In the Acrobat .pdf version and paper version I presented information from the SR Batteries Web site, but just click the photo of the X250 and get your info direct from the source!

Plane Ratings
From: Andrew Willetts andyw@mindspring.com

Last month, Andy told us about these planes, now here are their ratings. KM

Here are my ratings on the three planes I have built and flown so far (I am still building my Spirit 100, and also have a 36" P51 that I don't think will make it on electric power)..

Mirage 550, Goldberg ****

Originally learned to fly with this plane using the standard 550, 8x4, Jeti 35 ESC w/BEC, 7x1700RC. 4xHS80 servos, built with 8" ailerons (two servos for flapserons) Beefed up with an Astro 605G, 11x8 CAM, 7x2000RC cells now 54oz, ROG about 30'. Really climbs, still floats in good weather. Landing gear is too soft (for my landing ability), otherwise a good trainer.

Flame 66", Hobby Lobby ****

Astro 625G, 217D ESC (no BEC), 12x7 CFK prop, 14x2000RC, 94oz, 4xHS80's (w/flaperons). Performance is stunning, not quite vertical (I could add 2 more cells), 10-15' ROG and 5 minute acrobatics, 90 mph+ performance. Longer at partial throttle, but that's not why I built it!

Zagi 400, Trick R/C *****

Standard speed 400 & 4.9x4.3, FMA mini 30 ESC w/BEC, 7x500AR, 21oz, 2xHS80's. Hitec 555. With 8x500AR cells and a CAM 5x5 race prop, it tears up the sky! An absolute blast. I have not flown anything else since building the Zagi. Even 2 oz. overweight, the performance is excellent. Tricky at first, but rewards patient learners. Virtually indestructible, makes a great confidence builder.

Rating, Mirage 550
From: Glenn B. Campbell gcampbel@seidata.com

If I built Goldbergs's Mirage 550 straight from the box I would rate it ***. It has insufficient climbing power and has structurally weak areas in the landing gear attachments. The fuselage tail area is very delicate. The tail wheel is a joke, and the wing saddle is not very definite. Overall the fit of the parts is OK, but some are on the sloppy side. The plane does fly well, gentle and graceful, very forgiving.
I built the Mirage with some compensating modifications. I used the stock motor, but added a Master Airscrew 2.5 gearbox and a Top Flight 11x8 prop. I mounted this combo with a Sonic Tronics mount to the stock firewall. By mounting lower on the wall and tilting the wall down and back I was able to maintain down force angle as specified on the plans and keep every thing enclosed in the cowl. I did have to rebend the landing gear wire to get clearance for the larger prop, but the track is still wide enough to be stable. I substituted an Astro Flight 215D ESC for the stock on, off switch. Receiver is a JR 600 without the case.
With 7 RC-2000 cells it pulls 27 amps on a fresh charge then settles down to about 24 amps. I have not flown it to BEC yet , but my last flight was about 17 minutes with some power still left. Performance was a total transformation. This thing climbs out very well now, and I can throttle way back when up to altitude. It's still no racer, but acts like a normal plane with no strain, and it is a delight to fly now.
Other modifications included boxing in the landing gear wire retainers and adding some small gussets to the tail for strength and to keep the antenna away from the elevator control rod. I replaced the rubber tail wheel with one that won't flop over. I built my battery pack in the stacked configuration and mounted it under the wing. With only 2 servos under there, I had lots of room. It turned out that I needed that room. With the Mirage's long nose and the extra weight of the gearbox, mount and prop out front, the battery pack had to be placed pretty far back to get the proper CG. I mounted the receiver and the ESC underneath in the old cramped battery compartment. I do have to take off the wing to replace the batteries now, but Oh well! I used Ultracoat to cover it with and painted the trim. Overall weight came out right on 48 oz.
In summary, the basic design is good and with a little work can be made into a delightful flyer.
Glenn also sent along a couple of photos taken at the E-Nats in Muncie.

The Ilyushin IL-30 flys!.....
From: Grant Calkins CasinoOp@thegrid.net

It was a very exciting day! My electric IL-30 Russian heavy bomber took to the skies in it's maiden flight this morning at (where else) Edwards AFB...and it flew!
In the capable pilot hands of Tony Frackowiak, it lifted off the ground after a considerable run and climbed gently. With both EDFs humming, pass after pass over the desert strip was just so scale looking some onlookers were sure the Russians were coming. The second flight was timed at over 6 minutes and there was power left over - guess those 3000 mAh NiMH batteries do give longer flights after all! Only casualty was a fried ESC - the AstroFlight 217D is rated at 30 A and I'd never had problems with over-powering it, until now. MotorCalc rates this plane's battery draw at 46 A at takeoff, and I guess it knows what it is talking about.

Electric Trainer
From: Ron Oakley ron.oakley2@sympatico.ca

Ken for what its worth,
I learned to fly on a Great Planes PT electric. It flew very well on the supplied motor and 7 cells.
After I got my wings I started to change thing. I replaced the motor with a Goldfire and ran it on 8 cells very nice..
Then I bought a master air screw 3.5:1 gear box. Big difference. It R.O.Gs in about 15-20 feet. Nice performance on 8 cells with a 12x6 electric prop.
Right now the PT has being converted to an almost Pete and Paul. I call mine a Pat and Ron.
After the last kiss with the ground, I flipped the fuselage upside down and mounted on some sticks and Pat and Ron was born.
It flies even better. At the moment I have a speed 600 7.2 volts 3.5:1 gear box and a homemade 13 inch folder. I use 9 cells. 18 -20 amps, 8.5 volts to the motor. The plane weights 52 ounces.

MISS & EFO Fall Flyout

The weather predictions were dire for Sunday, October 17. A cold front passed through SE Michigan during Saturday evening bringing high winds and rain. Sunday dawned very gloomy and chilly. Tom Blaszak called about 8:30 to check on the weather up here. Reporting from my deck, I told him that it didn’t look good, but he said he be at Camp Dearborn about 9:30. I got the EFO portion of the food stuffs ready and headed out. I’d not loaded my plane. I got about 1/3 of the way there and thought I’d better go back and get it. It was a good thing I did.
When I arrived there were several electric fliers already there, and a few of the glider folks. The winds stayed down enough, and temperature rose enough that we all had a wonderful time, flying, talking and eating.
There were about a dozen fliers, mostly electric, with several of the glider folks having eplanes as well. Many of the dozen or so fliers brought wives and children. It turned out to be a real picnic. Tom served up hog dogs at one end of the table, while I served up beans and chili at the other. Pop and chips were also available.
Tom and I talked about getting together for a spring opener. Sounds like a fantastic idea. We hope that weather is a bit better then, but we sure had a fun time. Thanks Tom, Al, Norm, Wally and all the MISS folks!

Midwest Essence Rating
From: Bill Mecca wmecca@epix.net

I recently completed a Midwest Essence that was built in the V tail configuration. Since I had no experience with V tails, I did not invest a great deal of money in this bird. My mistake. With a Speed 600 direct drive on seven cells (1000 mAh) and using a Hitec 3 channel for guidance I have created a great flying machine, rock steady on climb out and vertical, nice thermal capability, although that should not be a surprise.
The aircraft appears to be very short coupled due to the much larger V tail. I expected a bit more nervousness in the flight. That did not happen. I'm going to retrofit a cobalt 05. It will then be a great airplane. 4 stars.

CYA GLUES A HEALTH HAZARD


From: MerleDavies
28523 Dino Cir.
Chestorfield, MI 48047-4319
Marine City Radio Control Club
Marine City, Michigan

Perhaps the information below, condensed from the article in "Modern Aviation" is worth insertion in your newsletter.

Material Safety Data Sheet informs readers of the harmful effects of CyA glue, which flying model builders use. There can be potential health effects if the adhesive is not used out-of-doors, with a fan for good ventilation, or a paint spray respirator. Cya glues contain Eythl Cyanoactate the most harmful, while the oderless type uses Butyl Cyanoacetate which is much less harmful, and more expensive. Alternate for the above are slower epoxies and aliphatic resins like Titebond II, Sig - Bond, and Carpenters glue.
The strong odor CyA adhesive acid component can cause damage to the eyes. The burning you feel is the acid etching the lens of your eyes, slowly destroying your vision. The vapors slowly burns the air sacs in your lungs, combining with the moisture to start sealing the tissue, causing hard breathing as in a severe asthma attack. Possible nerve damage and itchy skin problems can result. This product is giving us lots of warnings, so it will be used correctly. Children should not use Cya.

Also from Merle
BAMBOO USED FOR MODELING

In the 30’s and 40’s bamboo was very popular for the construction of light weight models because of its strength-to-weight ratio. The material can be split, then formed into curves for wing tips, tail surfaces, sometime fuselage stringers. Only small, thin strips of 1/16, 1/32 and 1/64 square sizes are required, thus small amounts are necessary. Model suppliers no longer carry the product, so picnic supplies may be a convenient source.
To prepare bamboo for splitting, shave stock to the proper thickness on the dull, soft side. The shiny side is used because it has the most strength. Split stock with a heavy, sharp knife cutting edge placed on the wood at the desired thickness, push the blade slowly while working side to side. Working too fast will produce uneven width strips. A bit of practice will produce desired results.
Form bamboo by heating over a candle, light bulb, soldering iron, stove, etc. Place the strip adjacent to heat source until the shiny surface looks oily, only then begin to form the curve with your fingers, a little at a time. Over bend the curve, as the bamboo will spring back some when cool. Hold in the bent over position until wood is cool.. A bit of practice is necessary for satisfactory products Regular modeling cement will hold the bamboo in place.

US Scale Masters Championship
From: George Heiman Catgeo@aol.com
Bob's plane on the ground and in the air.

Hi Ken,

I'm sending along a couple of photos I took of Bob Benjamin and his big electric Taylorcraft at last month's US Scale Masters Championships in Phoenix, AZ. It just worked out by accident that I was in the area on vacation. He seemed to be scoring well, but I have no idea how he finished. They had a large crowd at this event on the days that I attended, and it was covered on local television. The quality of workmanship really has to be seen to be believed. The announcer always let the crowd know that Bob was flying an electric airplane. It still seems strange to me how many people are unaware of the potential of electric R/C flight.
Thanks, as always, for the great newsletter.

Thanks George. We all owe Bob a HUGE thanks for all he’s doing.

Using E-mail to Enhance E-flight

The following is presented because it shows how useful having email and access to the world wide web can be. Weldon Smith had a question about CFK props that Andy Willetts mentioned in a recent Ampeer. Here is how an exchange of e-mail helped Weldon.
Weldon Smith email - lasfws@mc.net
Andy Willetts email - andyw@mindspring.com

I don't ever remember seeing a reference to CFK props before (in October Ampeer). Can you tell me a little more? Where do you get them? Who distributes them? Perhaps my local hobby shop can get them if they know who the distributor is. Thanks for any info you can send.
Weldon Smith


They are the Graupner carbon fiber folding props. You get the 'normal' gray ones, then CAM - used more for sport racing I think, then CFK is top of the line. They look a little like the CAM props, but they are hand-laid fiber mat, and works of art to behold. The performance difference between these and the regular (gray) folders is amazing. They're slippery little suckers, and give me more RPM and thrust at lower amps. Plus they're $30+ per pair of matched blades.
I broke one prop when the thing veered left on takeoff and I didn't clear a pilots box (empty!!). Check out www.graupner.com and the props are at www.graupner.com/prop.html - although I get everything electric related thru Kirk Massey at New-creations ( www.newcreations-rc.com ).
