Thanks guys, BTW I'm just the camera guy and video editor. The pilot is a 15 year old boy.

Greg1, the balance point is just what the manual recommended.

FlyHard, the prop is a Mejzlik 19x8. Ailerons is stock configuration with JR 8411s. Did have flutter problem before but when he switched to metal arms, it solved the problem. Also seal the hinge line..

Yea, IMO the Moki is not power enough for some IMAC manuevers. Once you do a verticle snap roll it just does not want to climb anymore. If you like doing 3D, I would go with the MOKI for the weight. If you do IMAC, I would go with a 50cc gasser.

P.S. Dave Patrick thinks a MOKI 1.8 is tooo powerful for this plane.

Will shoot videos of my H9 Edge and GP Giles 202. They 3D good as well. IMO the H9 Edge will probably the ultimate 1/4 scale 3D machine.
