This kit has been discontinued. This page has been left on our web site for historical perspective. We recommend the Heli-Roc model if you are looking for a good competition style helicopter model.

The "Micro Whirl-A-Tron" is complete helicopter kit designed exclusively for the 10.5mm micro motors. This minimum diameter diameter rocket is used to get maximum altitude, and then transform into a gyrating helicopter for incredibly long descent times. For helicopter duration competition, this model will be very hard to beat!

Included is a molded helicopter hub -- a marvel of minaturized manufacturing -- a molded sliding piston, a 10.5mm dia vacuum formed nose cone, die cut fins, balsa for the rotor blades, and complete step-by-step plans to build this complex model rocket.
