We're flying one with a Moki 2.10. It fits perfectly with the radial mount. It torque rolls like a top, spins real fast. In fact it rolls every way real fast. My favorite manuver is a "Turbine roll" - starting deep right perform a 4 second slow roll, a 2 second roll, a 1 second roll and a full deflection roll (prob. 550-600 deg./sec.?). Aside from flat spinning it into the ground it's been great. No problems with tip stalling or anything else. Check the incidences! I've heard about some with -4 on the tail, warped wings.... set everything to 0-0-0.
