I just bought a mmp and a takin 5.5 combo... now the problemis when I run a 2c 5000mah the motor seams to hit a rev limit and just surges on top . But I have no problem with a 3c5000mah..any help would be help full..it is censored I have it hooked up right..

a 5.5 on 3s, holy flying f-bombs i bet thats a bullet

My guess would be high amp draw causing the internal bec to have issues

Bypass the bec and see if it helps

Cheers

Ya its way to fast for our track.. and how would i bypass the bec exactly. Not to sure on hoe to do that. I'm kinda new to this.. and thanks for the quick response you guys ..

What brand and spec are you batteries ?


A couple of ways to bypass the internal bec

Plug in a normal RX pack style battery to power you receiver
Disable the internal bec by removing the red wire in the throttle lead

Or

Install an external bec
Gets wired up like this




Cheers

thank you. ill try that.. just one more question ..do I plug the external bec into an aux port on the receiver?..

Any spare port will do

Cheers
