Hi, can anyone tell me what sort of RPM, AMPs, I should be pulling on my Trex450XL. Running Align 400lf motor, 35Amp speed controller, Polyquest1800XP battery and Carbon blades.
Cheers Ian.

I beleive most people pull an average of 10-12A during hovering. You can work it out as follows:

Average Amps = Ahr put back in battery x (60 / flight time in minutes)

e.g. you put back in 1500mAhr after a 8 min flight (hovering only)

Average Amps = 1.5 x 60/8 = 11.25A

2400 rpm is the recommended by most people but I've never measured mine.

Hope this helps

Thanks, I have a Hyperion Emeter, and chkd that it was pulling 14.6 amps at 2430rpm. So this sounds spot on. Cheers Ian.
