Crawler Steering?

It seems to me that it would be necessary with all the demands of rock crawling. The one time I ran my Hitec 645mg with a straight bar on it I stripped the metal gears in about 5 minutes and had to buy a new one. :002:

Like others have said, in a crawler setup you would lose too much steering using servo savers. I use 5995TG servos for front and rear steering duty, with aluminum servo horns. Powered straight off the 6 cell pack they are putting out over 400oz/in. With high torque servos a plastic servo horn can be use as a weak link in the set up. You won't lose the steering like a servo saver does, but it will break/strip if something take a hit.

I used the ofna alum servo horns which have a plastic spline insert, like sven says it's a good weak link to use as they will most often strip out before the servo does.
