Is there any way from preventing the servos from jerking when you switch to the on position?

    There is no way that I am aware of.· This is actually a quirk with the servos themselves.· Even on R/C Cars, Planes, etc. this can happen at power-up.

    Ok, thanks.· It is really awful when i have 8 servos that all move a little bit at startup.

    I know what you mean.· On a Hex Crawler with 14 servos it's even worse.· This subject has come up before but non of the suggestions was really useable because it is a quirk with the servo itself.· I'm not sure if Digital Servos do this or not.· Most are compatible with standard servos, but I haven't actually used any.

    I've got a bunch of HT-5645's but I haven't powered them up yet to see if they twitch.

    But, I do know that the RoboNova powers up smoothly - no twitches at all, so I suspect that Digital Servos are immune to the twitching.

    Kenny,

    ·· That would make sense.· I had hoped to hear that this would be one of the things overcome on Digital Servos.
