I disagree with Walfet. It's the combo of a high power servo, an ESC that can't provide it and Spektrum's minimum voltage requirements.
The rx doesn't provide any power to anything, that's the ESC's job. It simply uses it, like the servo. The +&- pins in most rx's are bridged. Think of it as an internal y-connector.
When power demand is higher than the ESC can provide, voltage drops. It's this drop that causes the brownout (the rx "reboots"). I use a 1258 with a BH120 and an SR300. I use a cap because of the power requirements of the Savox servo. I had 3 brownouts before the cap, none after. It's not the end-all, be-all, but it works for me.

Servo horn Savox?
Do the Savox servos need a "special" servo horn? I have used the "standard issue" Savox servo horn but there appears to be a bit of an angle going from the servo to the ball cup. IOW, it's not perfectly straight.
Additionally I broke my first plastic servo horn yesterday. I realize aluminum may have prevented this, but, would that have put more stress on the servo and possibly ruining it.
Also, I'm running the Avid aluminum bellcrank. Don't know if that matters or not, but, point being the Avid bellcrank does away with the servo saver. *sigh*
Any input?

If your using a horn other than the ae ones just move your steering to full lock both ways by hand to make sure there is no binding or anything hitting.
