I get a combination of power loss and glitching where the steering just won't work like they way I want it to and I end up crashing all over the place. When my car stops moving with loss of power it will usually get going all by itself again after 5-10 seconds.
I'm using an Airtronics M11 radio with the Spektrum module so I tried replacing the receiver and still had the same problem from time to time. I tried using a Futaba, Hitec and finally a Savox steering servo and still had the same problem. The only conclusion i can come to is that the problem is with the ESC on my Orca Spark brushless system. I never had this problem when I was racing with a silver can motor. The weird thing is I use the same Savox servo and Spektrum receiver on my touring car and I never get these issues.
The orca spark system bec is only rated at 2 amps, not near enough for todays servos. The bec circuit is likely getting warm & losing efficiency. I would try a cap or bec.
