Servos "Twitching"
#1
The servos on my truggy randomly twitch. For example, when I'm going throttle-brake throttle-brake the steering will twitch sometimes. Or when I'm steering back and forth it will go wide open for a second. (Tested while not running for safety
) Running Protek receiver pack with losi regulator switch, and spektrum 3100 receiver. Any ideas or remedies?
Thanks.

I had a steering servo cause that same issues last year wen I gave it full throttle the truggy would turn left?? On the starter box the throttle and steering would glitch. I sent it to savox and they said the steering servo had a bad processor or something. Hope this helps.

And yes i have had a lot of glitch issues with Spektrum stuff but generally with electric cars, i had a lot of problems when using the sr300 receivers normally much better with a 3100

One other issue with digital servos is thhey are constantly trying to center themselves. sometimes when the gears get worn they will bounce back and forth trying to center. what brand of servos. At least check the gear slop. a new set of gears may help.

Great choice of servos, bypass the switch and try it. Bet that fixes your problem. You wont hurt those servos with a full 7.4. I run a 1267 and 1268 with a Protek 2300 mah flat pack. No regulator needed. You dont want to haul that cap. around on your truck unless you have too.

Your welcome, i hope it cures the problem. The first few times i went through that crap it just about drove me crazy. On a side note, i dont run any type of cutoff, i always charge my battery before i go to the track and on long days i might hook it up for a few minutes between heats, i have never had an issue of running one to low. May not be the best way but it works for me.

A 1257 is not high voltage. I've heard people running them direct to a lipo, but, I wouldn't. I have a fluorescent desk light by my work area that when on, sometimes makes my servos twitch. I have spektrum receivers also. Just a thought.

The problem is that you are running the Losi Regulator. It is only a 5A output.
Both the 1268 and 1257 together will exceed the 5A current on the Losi Regulator.
You either need to run a 10A regulator (Orion makes one, but it's cumbersome), or bypass the regulator and not run one. Use either a LiFe Rx pack or NiMH Rx pack.
