Hi Avi:
So good to see communications coming thru, considering.
Since you're experienced with Heli's, the basics are really the same. I fly the Trex 450SE & Sceadu 30 and really have similar set-ups.
In the electrics, you're looking for a head speed around 2000-2500 for stability. The ESC's do have GOV settings, but they're really no bargain... Gov's for the Nitro's are far better. I have a Phoenix35 and use "normal" flight setting which works perfectly. In reality, as with Nitros without Gov's, Properly set up Throttle & Pitch curves will give a fairly constant RPM anyway.
Why not try
www.trextuning.com and set up your Heli by the Trex book. Then modify as necessary.
Good Luck.
Lloyd
