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)
