Default Servo Twitching

If a standard 4.8v battery is charged untill charger goes to trickle which is usually around 5.8v, can this cause servo twitching at the higher voltage?

Thanks, Glenn

I'd say no...because most servos can run on a 6.0V power source...when fully charged would be 6.8 to 7.2 V......
If you have a glitching servo look at how close to the transmitter the receiver is if you're close.... back the transmitter away a few feet.....or if you have an extension remove or replace it.
If you're glitching servo is on a dual servo set up using a Y make sure both servo are the same......lastly look at your on/off switch

You can bypass the ON/OFF switch by connecting the battery directly to the receiver. I have corrected twitching many times by installing a new switch. Now I only use heavy duty switches with heavier wiring and gold contacts.

I have had this on Futaba gear usually on channel 1 with 4.8 packs and it goes away if you wiggle the sticks for a few seconds taking the surface charge off the pack.

But I do not understand why it happens because if I fit a 6 volt pack I get the same thing happening. ?????

Electronic gurus to the front please.

I see it all the time with a freshly charged batteries. Why?? I haven't a clue but as soon as the top charge is removed after the first flight they no longer twitch. I have some JR analogs that will do it every time.

I have it on several of my planes and skydivers - almost all the time its the radio to close to the receivers -dont ask me why - all the old timers swear its the servos ,so I just smile and have the plane flown anyway and all is good astrhe ol timers kibitz on when its gonna crash - been going on over 3 yeears so far and all planes flying - never a problen when radio over 3 ft from plane

Me , I would not worry about it and just keep radio a few ft away from plane when trimming and go fly and injoy
Don

PS- Im 72 but Im not in the old school class, mid young guns have a lot of knowledge also , new young guns ,heck they have no fear and do stuff thats not possable and it works,
