I'm new to this R/C fun and love it. i purchased a almost built old 172 at a garage sale. .25 size, finished and tried it out. on take off the plane rolled to the right and smacked the ground. fixed it. to make things short it did this everytime, untill the last fix, i mounted the engine straight up with no angle to the right. it only had about 2 degrees to begin with. but with the engine straight, it took off straight. whats up with that. everything i have read says you have to have some angle for for torch. any thoughts. rick near elderton
I'm going to suggest the plane didn't "roll to the right". I suggest you pulled it off the ground too steeply, and it stalled, which made it snaproll to the right.
I suggest that coincidentally, after you changed the mounting, you were more cautious in taking off, and let the plane gather some more speed before it lifted off. I'll bet you could take it off now, cautiously, with lots of right thrust. These things will take off and fly quite well, with or without a lot of right thrust.
Just my 2ยข worth, good luck!
