NEED ADVICE FROM EXPERTS...
Hi guys..
my setup is

Trex500
Torque tube
Stock motor and esc
13t pinion
2x 3S 2200mah 30C batts

Ok, I haven't tached the rotor but I am at 95% on throttle @ idleup and I am getting aroung 4.5 minutes per flight of mild 3D. My question is, I have a 14t pinion, will it help to put that pinion and reduce accel on motor to get more time? I mean if I put a bigger pinion I would get more RPMs rigth? but I don't need more that I have now I think it's close to the 2700-2900...

So what to do?

If you want more flight time you need to go down to a 12T pinion, decreasing headspeed.

Yep, drop it down to a 12t for longer flight times.

My dad is using a very similar setup and he gets 7 minutes with a 12t of sport flying.

Thanks Beeflyer and blbills, but using a 12T pinion wouldn't reduce the RPMS? I am in the process of jumping from mild 3D to hard 3D and after mid time flight when the batts are a little lower I feel the revs coming down and I dont quite like it like that, maybe it's not the time that I need to improve maybe its the batt comsuption... so what to do?
