Careful, you are over drawing the 2200 and WAY over drawing the 1350 if you re using it for the 57 amp run. I suspect you are getting big voltage drops.

Or just use a correctly rated ESC.

Yes i can put in bigger esc. I have 100A ESC, but thats not the problem.
like arejr said. I will pulling too much amp out of the battery. Max amp from 1350 25C lipo is 33A. Max amp from 2200 25C is 44A. I am pulling 57A on the bench. In the air, It should pull less amp than on the bench. Gliderdrive SK3 Motor is rated at Max 47A.

I will get my batteries pregnant in no time.

Yeah your are right. I missed that you were using the 25C battery.
I've been using the Heads Up 50C batteries, they work really well for the price. Their 1300mAh 50C is rated for 65amp continuous and 130 max.

Still he is over amping the motor. If you were hitting 50 for 30 seconds you would probably be fine but 57 could put you in overheat land.

Update: I've been using my Turnigy Glider Drive motor for 2 months. (3858-840kv with 12.5x7.5 Aeronaut CAM prop on 2200ma 3-cell lipo) I must have well over 100 launches on it.
Still running cool and smooth. I'm very happy with this motor.
