RCU Forums - H9 Sukhoi-feedback

Very nice engine- a huge upgrade in overall power.
I would suggest using either largish cans OR the new individual in cowl mufflers from RCS
Best props -probably mejzlic 26x10 -or-27x10--for fast throttle rsponse and always in the full power band at zero airspeed.
Presently the engine is lugging around 29 lb Extra (an ARF) which flies verywell thru the Unlimited IMAC stuff.
Having said that - I would still opt for a much lighter plane for the new "no Zone IMAC sequences -
I am going for my own design - as most of the ARFS are still too heavy to suit me -_in the Sukhoi - it will have lots of reserve power--It is sized right -in my book.
