    servo torque

    how much steering servo torque should i have for 8.62in tall weighted tires truck probly ways 16lbs or so when crawling

    I have 333 right now, and its a joke, somehow i doubt going up to 600(hitec's new powerhouse servo) will be enough.

    I second that - Two servos and dividing the load I feel is better than putting all the eggs into one high dollar servo basket. Im pushing dual 208oz (416oz) hobby city servos and they do pretty well. But I know hitec are very good as well. I believe the one servo setup is best suited in an attempt to lighten up the speedy revos.

    my .002c

    I'm ordering 2 of this for my summit.

    I'll have to work out how to tighten the servo saver or take it off completely somehow as this is my current problem....

    Traxxxas part # 5344x. heavy duty spring. You might try it, if you haven't already. I used it when I went to a single servo setup.

    my .002c my problem is the servo saver. It doesn't matter how strong the servo's are, if the servo saver kicks in, the wheels will not perform (turn) effectively and when you want it to.

    Thanks caveman4466... I'll order that too....

    yeah the summit comes with the heavy duty spring, but the revos don't.

    you want to take the servo saver apart and drill out a washer so you can put it on the narrow spring side. add as many washers as you want, might need to get the aftermarket aluminum version if you want to put a lot though, because it will bend.

    wow, big spender lol.

    yeah id like to run two of those as well, but Id not like spending $300+

    yeah my 7955tg i think is called thats 333 at 6v, is kind of wierd it like jitters at the slightest touch, i have to go over to the truck and try to find the magic center buy turning the wheels left or right ever so slightly, so that it stops making noise.

    kind of think theres somthing wrong with it, ideas anyone?

    i wonder if hitec could fix it.

    Strange then, I have the problem in my summit not my ERBE. thanks for the washer tip.... I placed a flat 5mm diameter washer on the narrow spring side and placed a flat 10mm diameter washer on the wide side too. both are 2mm thick and fits perfectly.

    it performed better than it did. it was brilliant.

    My one is a bit noisy but I've read somewhere that that is normal for these powerful servos. They are quick and respond very well hence when you turn the TX wheel even just slightly, you will notice the truck wheels will follow. (well, my one does anyway)

    I adjust by using my DX3R and set my end points. works for me.
