Please don't take this the wrong way.
Why are you using full throttle to take off.
I bet that plane will take off at half throttle with no problem.
Why are you gunning the engine to full throttle.
If you did that to a car with an oversized engine (rear drive) you would be spinning all over the place.
A plane will not be any different.
Apply throttle slowly and when you get to half, stop
Let the plane build speed. If it needs more speed, then give it a couple of clicks.
You don't need full throttle to take off so don't use it.

I've been around RC planes for many years (most recently sailplanes and dynamic soaring) but I only recently got back into glow.
I am having major problems controlling my plane (a low-wing Stick taildragger) on the takeoff roll. The plane will make a 90 degree turn to the left at full throttle that is barely correctible.
Is this "normal" for this type of plane? I know some amount of right rudder is necessary on takeoff, but this is truly ridiculous.
Also, could my landing gear/wheels be at fault? There is quite a bit of play in both the main wheels (Du-Bro low-bounce) and the tail gear.
THe plane, for those who were wondering, is a .46 size Sport Stick from Hobby People (pretty good flyer, actually)
