| Hi,
Whenever I do loop, the loop does not round and big. Following steps are what I did
1. Stall turn at high altitude to either left or right hand side
2. Fly heli back to my position then pull cyclic back while keep the positive pitch until it hit the top of the loop then reduce the pitch to 0 or a little negative
3. When heli at 270 degree, I return + 5.5 and fly away
Above steps does not give me a big round loops at all but at least it is a loop. It happens to both of my 30 size and 50 size glow engine heli.
I have read some theory says that the pitch is 0 at the first 90 degree (1/4 loop) of the loop then gradually reduce to - 3 or 4 at the top then +5 degree at 3/4 of loop. Follow these steps and I end up with the heli stall and tumble at top of the loop.
I am wondering how to do a big round loop? Do you have any trick/technique to guide me.
Thanks, |
