Trex 600 w/ roughly 4.5hp and pitch set up similar to those used for the most extreme 3d flown with them. Powered by TP Extreme 6s1p 5000mah. Requires T-Rex-microHELIS_EA model posted by yogi149. Oh, also forgot to mention, once you spool it up, get off the ground quick. There is something weird with the collision mesh on this that for some reason my variant has a tendency to explode violently when sitting on the ground spooled up.
