I have been running that exact AR6200 receiver on a 50 sized nitro heli for over two years now (5 high torque digital servos and a gyro all running at once), but with a 6v Nimh pack that was new at the time, and not once have I suffered a single brown out issue or something even remotely related to a glitch. On that basis, I'd say you have hit the nail on the head re your problem!
Give Kiwibob72 a CIGAR!
Yup.
A lot of newbies, and some "old timers" forget that a signel standard server can draw close to 2 AMPS (!!!) as it approaches stall.
A bit of binding, times the number of high draw digital servos you are running, plus the age of the battery pack and you have a WONDERFUL recipe for brownouts. One or two servos alone can cause the problem.
Upping the voltage is not a bad idea, but not exactly required, upping your battery capacity however is a MUST to avoid brownouts, or do both to be safe.
