I am having a lot of trouble taking off. I fly a Kadet LT 40 with a super tigre 51 turning 11/7 prop. I have just learned to fly by my self and my landing are really good but my take off is really bad. My club has a 40ft wide runway and I use all of it taking off. I can not hold the plane straight. My instructor says to get rolling and then go full power. I can roll all day with no problem but when full power hits, its like a drunk preacher trying to walk. I get took off but its as dangerous as it gets the way I see it and I dont know what Im doing wrong. The way i see it if I dont know, then I cant fix it. MY instructior offers no advice. He just says lay with it. Is it the full power thats making it go crazy? Ive straighten the nose wheel perfectly, no help. I changed the pushrod location in the servo to the nearest hole and no help. What is up? Can some one offer sound advice. How fast do I really need to be to take off. Remember I just soloed so Im no expert. Thanks Roger
