External BEC needed for RX8 high voltage/Mech brakes?

Running a receiver battery won't tell you if the servo is drawing excess current - the problem may seem to go away, as the load will no longer be on the ESC BEC, but the root cause may still exist. My guess is that the servo is drawing excess current, as mentioned a couple times in this thread - dropping in a good servo will fix the issue. Also mentioned in the thread - you get what you pay for with servos for the most part. You don't need a super powerful servo, either - there is no throttle return spring to fight. :)

Last night I ran one last test with the existing brake servo. I disconnected the linkage and it still drew enough to shut down the BEC like I'd been describing.

So I went ahead and swapped it out with a Traxxas standard servo I had laying around the shop. From a limited, midnight, shakedown run it seemed fixed but I'll try it today and really wind it out. I'll report back in a few hours. The servo was just drawing too much juice it seems.
