Well , I also went too the LHS and picked up a CC 10a BEC , put it in and it seems to have cured my problem ? So why cant the BEC in the Mamba Max Pro do the job ? Is there some kind of fault with them ? I am using a high torque servo (JR 9100T) but I use that servo in all my 1/8th scales and the MMP ESC is the only one that is giving me trouble .
