Thanks for your reply. I'll aim at around 2200 RPM to start with, and go on from there.
I'll stick to programming proper pitch and throttle curves, and not buy a governor yet.
I test flew the heli and had some disturbing observations...
While I figured that the transmitter is way to simple in order to fly a heli properly, I was suprised that the rest of the electronics is poor as well.
The servos are way to slow and weak, and take agaes to center.
The gyro is hard to evaluate, as the servo is really poor, and whatever good performance the gyro might be giving, the servo is the bottleneck.
For the finalle, they rolled the antena over the antena tube, in about the only manner an antena should not be placed. That causes glitches, and I guess that's why others have suffered glitches with these machines.
HOWEVER, mechanically, the heli is sound, and is rather cute. Metal is used where needed, and the swashplate and rotorhead assemply are smooth and moreover very precise, without un-needed play. It's a 120 deg ccpm swashplate, which minimized the load on the servos.
I ordered gws servos (I keep the budget of digital servos to the nitro birds...), and with the Futaba receiver and transmitter, I expect it to fly really nice.
Which leads me to another question: Is the Telebe HH gyro any good? It's rather cheap (around $55), but with electronics that could be tricky...

Thanks for the information, always good to hear other flyers' opinions.
Avi.
