I flew my friends H9 Ultimate through the unlimited sequence. It has a 3W 150 TOC, tried 2 props, the 3W 3D prop and the Fuchs 32x12. Flew sequences better with the fuchs. Airplane has no bad tendancies for IMAC, just takes a little more work that comes with flying a bipe. Only takes a couple of minor mixes, and the only one he has programmed in is for proverse roll. The airplane is very smooth, and to me, is almost as good as a Carden Extra or Fiberclassics. Hope this helps. It does also, 3D very well too.
