I have a Mamba Max Pro in my sc10 and when i land off jumps sometimes it will lose power. I have eliminated the on-off switch already, shortened the wires to the motor. Has anyone else had this problem. I even took the esc apart to see if the wires were loose inside and they were still sautered fine.

What radio and servo are you running?

Check all plugs ? Power, reciever, & sensor if running sensored.

Spektrum dx3.0s futaba servo, checked every connection i have the castle bullet connectors on the motor could that be the problem

What futaba servo though? S3003, S3050, S3305 etc etc?

I am thinking it could be BEC related, paritcularly given it's a Castle esc and a Spektrum radio

I had a mmp break a power wire where it is connected to the esc . I could not find the problem because it was broke inside the red cover . It broke where the solder and the wire meet .

try running a cap. 4600 uf should work. I run a 10000 uf noo probs mmp and spektrum don't get along too well with out security. If u kno what i mean
