could be the wheels are not aligned correctly.

Toe out is bad. excessive toe-in is bad. You want the dstance between center of the read to be barely less at front than at the rear of the wheels. Straight is OK, but not ideal.

From the CG at the wigh root at the bottom of the wing, draw a line downward 15 deg forward of vertical. The axle should be on that line. (this normaly has the front of the tire under the LE on a .40 size shoulder wing plane with 2 inch tires.) if the axle is directly under the leading edge... its usually not too far off for it to work. It is amazing how much difference there is in moving the axles back 1/4 inch on some airplanes though.

Don't slap the throtte full forward... advance it slowly.

On slick surfaces you need a tailwheel or something to help prevent the tail from whiping around. That coro fuselage on ice just dragging the back end may be a big part of your problem.
