BL crt.5 run hot.

[tkhoo]

Hi guys, i am done converted crt.5 to run BL and below was the setup. But after 3min run, the motor started run hot which as below

after 3min
motor-160F
esc-142F
3s Lipo-110F


my setup
esc-MM with fan
motor-Feigao 2731kv with heatsink and fan
Lipo-Flightmax 3s 5000mAh 30C
mod1 pinion-16T

Do you all feel that I should lower down the pinion to 13 or 14T so that the motor will run cooler? Thanks.
