RE: GP Super Decathlon
jimvines4244, I think that everything about this plane is already stated in this and a few other theads. Let me sum up with a few comments:
1. The .61 should be great for this plane. Mine has an .46LA, I can fly it around at half throttle, but more power whould be usefull. For example, to perform a loop I have to dive a bit to pick up speed. Mine balanced exactly on the recommended CG with this engine, so you might have to move the battery and/or receiver back for yours to balance. The recommended CG is just fine, I think
2. It's gound handling is bad. Advance the throttle slowly. Let it pick up speed before rotating, because it will tip stall. I don't know if your instuctions suggest washout, mine didn't but I know that GP suggests on their site to add washout and later kit instructions were changed to include that. I didn't build any washout and I don't have a problem. It might be better if you do. It's up to you
3. Keep the control thoughs down at first. 1/2" each way for all contols are enought at first. Later you can increase them
3. Landing are bouncy and landing gear are not very durable. I have order a Dubro LG, which has not arrived yet, which sould correct this problem
Thats about it. Give it time, build it straight and if you don't have any experience on taildraggers, practice on the ground until you are comfortable with its handling before trying to takeoff. In my opinion, landing are easier with this model than takeoffs. But that's me
Good luck and let us know how it goes
