This version of the Helix is made of heavier marine grade Meranti ply-wood which gives it more range and better wind resistance. Based on the original Mantis shape which was used all the way back in 1987 by Team MidWest to dominate the Round Rang Relay event at the first International Team Cup. The Helix is smaller and lighter and intended for easy short-range throwing. We have also made the elbow section a little rounder more like a Skippy to give it more hover. Has a range of 25-30 meters.
