ORIGINAL: Neil Guildford

My Decathlon didn't really fly a scale speed. 3 attempts at take-off all caused a hard left turn on the ground. Then I tried a hand-launch, which was a bit light and caused it to fly straight into the ground (broke the undercarriage). One last try, a hard throw into wind. It banked left and then immediatly came under control.
I was flying this thing faster than the other guys with there 40 size models. Unlimited verticle, stall turns, axial and barrel rolls then lot.
Having no undercarriage I cut the engine on finals and glided in. It was easy until the last foot when it dropped, luckily flat on its belly (no further damage).
I'm going to replace the OS 15LA with my AP Hornet 0.9.




I converted my wattage decathlon using an AP .061. The engine fit completely inside the cowling. Plane weighed in at 16oz with an onboard glow driver, HS-55's, and a 1.5oz tank. Flew very fast for its size and was very aerobatic. It always drew attention at the field and most guys would stop flying to watch it fly. It couldn't do a rolling takeoff either. I always had to hand launch it. Landed great though.

Status: offline 		twister55,

I've had a few of these 1/2a Stealths and have always loved them. They fly great and even make a Intermediate Flyer like myself look good.

One thing I didn't like was the 3-4 minutes of flying time. So, in order to fix this, I placed an additional 1oz Fuel Tank between the Elevator and Aileron servos. The square 4cell flat pack receiver battery rests on its edge up against the firewall (padded). After that I got 8-9 minute runs with a Cox TD .049 that tore up the skies on 20% Nitro fuel. Trust me, it really is easy and well worth while.

Note: The breather line from the interior tank attaches to the pressure tap on the engine...
The fuel line from the interior tank attaches to the fill tap on the TD...
The fuel feed line on the TD attaches to the Carb (Reed Valve)...
The overflow on the TD is blocked (small fuel line and screw) to allow the circulation via vacuum (think of it like an electric circuit)...

When you fuel. you unhook the pressure line and attach your syringe (whatever) there and unblock the overflow. When fuel comes out the overflow it is ready. REMEMBER to reblock the overflow and replace the pressure or the circuit will not work when you are finished fueling.

Also, make it so the cockpit is removeable (after the first one I didn't even bother with a cockpit...too much DRAG).

I read here that a couple of people were using two aileron servos. What a waste of extra weight. If you just heat up your flexible pushrod tubing in boiling water and hold the shape you want it works like a charm. Mine never failed or bound because I followed the instructions.

Finally, REINFORCE the tailgroup by using servo screws ( at least 4, 2 each side ) to hold the horizontal stabilizer to the booms. On my early versions this was the first place that failed ...ending in disaster.

GOOD LUCK

It weighed 226g (8oz) and had a Norvel AME .061 in it. I still have the wing. I should build another with an .020

Status: offline 		I did the same thing with a single constant chord Ace molded foam wing panel to make a Micro Hots. Cox TD .020. I did this in '91 so the smallest servos were Futaba S133 and a 114 Rx, made a 50 mAh battery from cells out of a rechargable 9v. I probably should revisit this because I know I could outfit it for a much lighter flying weight now.

Status: offline 		Cool planes! Here's my Herr J3 Cub. 48" wingspan, 3 servo's, throttle, rudder and elevator. It has a Norvel .061. I also put Curtek lights in it. Red & green on the wingtips. White landing lights, one on top and one on the bottom. Nice kit to build. Hasn't had its maiden yet. I'm also building the Herr Cub "windy day park flyer". I have the wings and fuse done, but that one is up in WI (my vacation build project). That's going to be electric powered by a Sprint 280.
