I have a BCP with metal head and stock TX/RX. I had a crash while dialing in the proportion. After the crash, the 4in1 kept twitching the servos! It would power up fine, then start to jitter a little bit. After doing that for a little, it starts to move the servos to its end point, then return to center, end point, center, end point. It does that once every second. What's going with it?
I verified the servos are fine with my AR6000, it doesn't move around. So it's the 4in1 that's doing the twitching.

Ok problem solved. Because there was no problem. While trying to find out why it is twitching, I noticed the low battery led on the Tx is blinking in sync with the servo movements! So as a hunch, I switched out all the batteries in the Tx, and voila, problem solved lol. It looks like this is a safety feature e-flite built-in to their Tx to force people to change their battery. It twitches the servos little by little and gradually increase it to force you to land safely. Kind of like how the esc pulses the motor when the battery is low I guess. Now we know about a feature on the E-flite Tx.

That TX comes as part of a total heli, battery, TX, RX, Gyro, ESC, charger, combo for $200! I think it's extremely generous to describe that as a safety feature. I suspect when the LED blinks, the TX battery dips, and the servos glitch.
But I'm a horrible cynic! :mrgreen:

Hey now, the led blinks in perfect sync with the servo movements. They're movements, not twitches. Once per second on the dot.

I think the blinking may be a feature. I suspect the servo movements are likely a side-effect.

Perhaps the blinking leds are drawing enough currents to lower the Tx output to cause the twitch? Not really a question, just thinking out loud.

That's what I believe.
