Hi Guys,
This is a new one on me...I have used Futaba's SBus many times, but just switched to Savox servos for the new Avanti XS as the JR's were not available, and the Futaba's were too large for the servo mounts.

I am using 2 JR 8411SA's on the flaps and the rest are all Savox 1250MG's which are also HV. I power it all with a Fromeco Sahara at 6.1V. I am using Electron gear on an RS-200 controller. The issue is that when I power on the Rx and hence the gear controller, then the rudder and usually the right aileron servo both go into a hunting/oscillating mode. I have control over the servos but they look like old galloping ghost style!!! The gear do not respond at all. If I unplug and replug in the Sbus leads to the affected servos (all on decoders) then everything settles in perfectly. The nose door has a Hitec 225 BB operating it, hence the 6.1V rather than 7.4V, and I doubt the JR 8411's on the flaps would handle the 7.4V either.

Anyone got any ideas? I will be doing some further investigating with servo replacing, maybe take out the gear controller, and higher voltages etc. but I thought if anyone had this before then I'd need not 're-invent the wheel' so to speak...

Thanks in advance,
Len
