Like you, I too have control problems. I am presently working on a LDS short kit for a free-flight B-36 that I am converting to 4 ch. R/C. I have the LDS short kit of a B-727 under way. And, I am converting Dumas's H-4 Spruce Goose static display 30" ws model to 4-ch R/C. No control issues here with me.
