HeliMax training gear attaches to heli skids to create a LARGE base for safer landings - heli is much less likely to tip over. Consists of a wood center section that holds four heavy-duty carbon fiber tubes, and four sturdy 1-piece plastic balls that act as wheels. Also helps stabilize the model in the air, by adding bottom weight that lowers the CG and reduces fuselage swinging. Can be used on .30- to .50-size helis. Disassembles quickly for easy transport to the flying field.
