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.
While I appreciate the offer and sentiment behind it .... I'll decline your cigar thanks .... cough cough cough
As for voltage, pack capacity etc, and taking into account the simple fact a DSM2 receiver can brown out at low voltage (which on a small capacity 4.8 pack can easily occur under sever servo load) - I never understood while people would EVER use a small capacity (1200mah or so) 4.8v pack on a DSM2 system akin to what I use.
Guys over on the heli forum I use have worked out that a nitro heli like mine for general sport flight will consume about 350mah off a pack in one ten min flight (5 high torque digital servos and a gyro under 100% movement all the time on a given flight), so even though I run 2450mah 6v packs, I still do not push the pack beyond 4 flights as I do not want get even remotely close to a KNOWN point of issue (brown out) that can be caused by the loads a big 7.9lb heli like mine can generate.
Currently I'm building a 65" P51 that will be running a total of 9 metal geared digital servos in it (including the two each in the flaps and retracts controls, so there are 5 for 'normal' flight controls), while I know from my heli that I can easily get 40 min of flight off my standard 6volt 2450mah packs with 5 digital metal geared servos in use, as I'll be running a gas motor that can run for + 30min straight on one tank, I am looking at putting a twin battery pack redundancy system on my receiver to compensate for the simple fact I'll want more than one flight in a day, and that I also have 4 other servos that will be drawing current at some point during landing and takeoff that I also must address.
The simple point is that IMO we all should be taking the time to ensure our battery that allows for control on our models is up to the task. Yes electrics are a dark art for most people, and while I am no expert or even close, I still have taken the time to learn that just because a power supply system I have in one model works fine, that that same syste m may not be even close to suitable for what I might need to SAFELY run another model. We all have a responsibility to ensure that what we set up is safe to run, and that failures to do so should never be acceptable in this hobby where we can and do have big 100kph 'bullets' at out control.
