But out of curiosity, My TLR is running the same receiver, protek 170s servo, rx8/ pro 4 hd on 3s and I have no problems with that truck, BEC on the rx8 would be at factory setting.
Gearing was 75/35, stock spur. Just ordered a 66t spur.
Ok, a few things here.
Stock BEC voltage is 6v on all units.
Gearing a 2.5T motor 75/35 is not going to work, and the 66T spur will make it worse. If you're trying to dump the throttle with this setup you could be asking the battery to deliver over 500+ amps! I realize this is likely a high speed car, but you'll need to roll on the throttle a little bit here.
Understand that the ESC has NO control over the steering aside from powering the BEC. If you're amping out the battery in this manner, the BEC may get a ripple current through it the receiver cannot handle. A receiver cap may help squelch the noise and cure this, but the gearing you're trying to run isn't sustainable.
