This is kinda a double post as I asked on the Electric off road forum. But do you think Id be able to run a JR 9000t servo with my Castle Mamba Monster ESC. I read on several forums about there internal BECs not handling HT servos very well. My sidewinder had issues cutting out with a 215oz HT servo. I know the MM is abit better than the Sidewinder but if I'll need it then I wanna start shopping around. If it makes a difference Im running it in my Revo BE with the standard Mamba 2200, TRX link 2.4 with 2 x 2s 4500mAh 35c lipos

Try it, if it has problems just get the external castle bec, will allow you to give more voltage to your servo if applicable. I was hesitant at first but was an easy install, and with the erevo you dont have problems with cables touching the drive line, been there....

Yea, I already started pulling the old ones out. Already grabbed up a alum. servo arm. But I hope it works out OK. But I never had this issue over many esc's and servos. Just the Sidewinder. But would having the one servo draw less amps or voltage than running two trx servos? Its twice the torque, but only one instead of two servos drawing off the rx.
