I just bought a used / crashed trex 250 belt drive. Got it all back together and set up. Flys great. I'd just like to know what the recommended throttle and pitch curves are. Can someone help me out ? I just quickly copied my 450 L
Settings for it. It's not right for this 250.

Thanks for any help

I'm not at home now but I know it's stock if that helps at all. It's a older version that came with the belt drive.

Pitch curves should all be a straight line 0-100. Normal throttle curve, try 0-60-70-75-80, IU1 90-85-80-85-90, IU2 100-95-90-95-100.

60% of the time, it works every time!

I think I may have found my problem why this heli don't seem right. My normal pith curve is set at
50, 42, 50, 75, 100. Isn't that wrong ??? IU 1 and IU 2 are both set at
0, 25, 50, 75, 100. That looks good to me.

Throttle curve set @

Normal 0, 65, 70, 75, 80
IU 1. 80, 75, 70, 75, 80
IU 2. 85, 80, 75, 80, 85

I set normal pitch curve to
35,42,50,75,100. The first number was 50 instead of 35. My mistake. Must have been why it was crazy on take offs.

I personally set all my pitch curves linear in all modes ,,that way I am never caught off guard ,,even in normal mode. Then setup the throttle curves or gov that suites you.

Setup is everything, All my heli's can fly far better than I can pilot them

Same for me 0, 25, 50, 75, 100 (all linear)

When I was using the stock Align esc / motor and a 15T. pinion I had to run a flat-curve of 100-100-100-100-100 to get some Collective-POP !
