ORIGINAL: ss40 Try to determine if QPCM or PPM/FM is set. That will probably be the problem. With the 05S's I believe I turned on the receiver first and then the TX as they are autoshift??
Golden Rule with all RC systems "TX On first - Off Last" this is stated in the TX manuals of most brands of RC systems, especially under range testing, and in the instruction sheet for that RX.
HFS-05MS "Micro 05MS" instructions.
TX on first is more important now than ever before as the modern RX with PLL, IPD, AGC and other similar features search for and lock onto a nearby signal and if TX is turned on later, the receiver may not then be able to lock onto the then correct signal. (Also beware that if the RX is ever turned on first, the rx whilst searching for a signal may drive the servos beyond their physical stops or pull control surfaces beyond their limits.) Further information available under "Glitches & Jitter in RX & Servo - causes and cures" on my web page.
