Well hello to everybody.
Although I read the posts from RR for almost two years it is the first time that I am writing one. The reason is a problem I have with the setup of my T-Rex 600. I have a CC Phoenix ICE 120HV and I recently purchased a Scorpion 4025-550(6mm shaft) so as to increase the power. The batteries I use are Outrage 10S 4200 25C and 2 X Turnigy 6S 3000 45C. However when I go out to fly with this setup, there is no power at all (significantly less than with the stock Align 100A ESC and 650L motor). I tried changing the settings from the ESC (8KHz, 12KHz, Outrunner Mode, Fixed End Points and Governor Mode, Medium Timing) but nothing happened. The heli just takes off and cruises difficulty as it has very low head speed.
The truth is that I tried another motor, the X-era 4030-2.5Y and had the same results. However I believed that it was a faulty motor and sent it back to Readyheli from where I had purchased it, for service (very good support and they answer immediately to my mails). From Readyheli they sent the motor to X-era motors something that I should have done from the beginning. From an accident I had with my previous ESC, a CC Phoenix 110HV than burnt into flames when I tried to connect it with 2 X Turnigy 6S 3000 45C batteries(old ones, not in live) I supposed that maybe the motor was hurt.
I also tried the Scorpion motor with a CC Phoenix 110HV, a new one that Castle Creations sent me after I sent them the burned one for inspection as I could not find out why that happened (since then I used it normally with the 650L and 6S battery). Same results.
Throttle calibration done properly. I don't know what else to do.
Thank you for the patience for reading my problem.
Happy new year.

Don't know what to tell you.
8kHz and 5deg. Timing is right for the Scorpion motor.

Try a larger pinion to bring the head speed up. That 650L has a 1220Kv.

Now I have a 12T pinion. I will try tomorrow to fly it with a 15T. However this is not normal because it is supposed to have 2850 Watt.

Thank you Heli 770 but I have already bought two motors and spent enough money. From my experience from the 650L high temperatures of the motor and the batteries are not very good thing

O.K. Problem resolved. I purchased a 17T pinion and it seems that I have a whole new heli. Extreme power. The sound of the spinning blades is tremendous. And the motor is unboggable. After the flight the motor is slightly warm so does the ESC. As for the batteries, I am not sure that they realized they just had a flight.
Thank you all.
