Hello Every one. Can any one give me some tips on my BL setup?

I have:
HDX3800kv Motor 12t pinion
Dynam 30a ESC (Set to soft timing)
1300ma Lipo
axe rx - 6EXH tx

It runs much cooler than with the brushed motor but I am getting the same flight times with the BL as the brushed(8min).

I tried 13t pinion and the flight time went down to 6min and the motor is hotter.

Thanks for all the good info.

That's the way these things work. Bigger pinion, better performance, shorter duration.

So if I go with a smaller pinion I will get better flight times?

Yep, here's a head speed calculator I used to estimate my gear selection.

OK thanks for the help. Oh one more gustion ...
For a longer flight time what kv motor should I use ?
