Recently I brought a HCP100S and a HCP100. Use HiSky protocol can bind both of them.
However, both not stable:
From time to time, HCP100S lose control for a short time (sticky servo), left side LED blink at the same time
HCP100 has shudders in all channels occasionally - cyclic has burst movements, the tail has sudden shakes.
Tried with radio came with a V922, it flys HCP100 perfectly. Though cannot fly HCP100s, once linked, the servo never sticky and the LED never blinks.
I also have a V922 bought more than one year ago, it can be controlled perfectly.
It looks like the Deviation HiSky protocol may not fully compatible to HiSky protocol, TX and RX out of sync once in a while?
V922 does not shudder at all, either the firmware updated or V922 and HiSky has different versions.
