Great video! I tried this right away on my OMP M4 Max with the DX9, an AVIAN ESC, FC6350HX flight controller, and OMP digital servos. It works perfectly. I’ll find out soon during flight operations if this makes the heli respond even a tad more precisely or quickly to control inputs.
Good conversation/info. Could you do an instructional video on "Holds"? I occasionally get this condition on my TX. Also, what is an acceptable number for framerate loss?
In Spektrum transmitters and telemetry-capable receivers, terms like _Holds,_ _Fades,_ and _Frame Losses_ provide critical insights into the signal quality and stability between the transmitter and receiver. 1. _Fades:_ - _Definition:_ A "Fade" occurs when _one antenna briefly loses the signal._ Spektrum receivers often use multiple antennas (typically two main antennas and sometimes satellite antennas). When one antenna momentarily loses the signal, another antenna might still be able to receive it. - _Significance:_ Fades are _short, minor signal dropouts_ that usually go unnoticed unless they occur frequently. Fades are tracked per antenna (e.g., Antenna A, B, etc.), allowing you to identify if a particular antenna might need repositioning. - _Action:_ A few fades are normal. However, if the fade count is high, consider checking the antenna positioning or the environment. 2. _Frame Losses:_ - _Definition:_ A frame loss happens when _no antenna can receive the signal for a short time,_ resulting in a lost data packet. The receiver compensates for a single frame loss by holding the last known position briefly, so control isn’t lost immediately. - _Significance:_ Occasional frame losses are expected and usually have no noticeable effect. But a high number could indicate interference or a less-than-ideal RF environment. - _Action:_ Frame losses should be minimal. If they occur frequently, check your antenna placement or consider adjustments to the model’s RF environment. 3. _Holds:_ - _Definition:_ A hold occurs when the receiver _fails to receive commands for 1 second or longer._ This is a critical event where the model stops responding to inputs and instead maintains the pre-set “failsafe” settings (often cutting throttle). - _Significance:_ A hold represents a _serious signal interruption._ This could be due to interference, poor antenna placement, or physical obstructions (e.g., large metal parts within the model). - _Action:_ Holds should be avoided. If they occur, check the antenna layout and inspect the RF setup. Holds indicate a significant risk to control reliability. Summary: - _Fades:_ Brief signal dropouts per antenna; minor if the count is low. - _Frame Losses:_ Short interruptions affecting all antennas; normal in small numbers. - _Holds:_ Critical interruptions lasting over 1 second, indicating a serious issue. Monitoring these values offers valuable feedback on the RF performance of your setup, helping to detect potential sources of interference or signal loss early on.
Sooooo Sean, did your friend then have both analogue and digital servos in the same plane? Having swapped out the digital one for an analogue one. I though it had to be all digital sevos or all anologue🤔
More great information Sean. Thanks so much. I guess I will update a few receivers.

Good video but too advance to me. LOL.
