Giles try this for your steering, I picked this up from another board also:
OK, a couple more discoveries. First, the steering. I am running the RTR. And I noticed that the steering servo was loose. Actually just looked close enough to notice it today. Turns out the 2 screws that hold the rear of the servo to the mounting block are too long and don't thread all the way in. So you can either cut the screws or add a couple shims. I added a couple shims and it's locked down nice and tight now. Much better performance.
And the next tip is for anyone using the JR R135 receiver. I had heard a rumor but couldn't find proof until I did this myself. But if you plug the battery into the battery slot of the receiver, you'll only get 4.8 volts to the servos no matter how big the battery is. Modify the battery plug so it fits into the AUX slot and just look at the difference! Much faster servo response and more power in the steering. It's a noticeable difference! I am also putting an R135 in my Nitro RS4 and my Savage SS and will be doing the same for them. Solves a number of problems with low steering power.
Perf, thanks for the quote. Actually, that was my post. On other days, I'm Candyman, a mod at
www.rcnitrotalk.com. And a new Mayhem owner. I've been reading along with this thread for a while because it contains a lot of good info. I'm just a buggy basher for now, but I've been hearing a few questions about the steering on both sites. This seems to have helped the symmetry and snappiness of my steering. Doesn't really increase the sharpness a whole lot. I'm still waiting to see how the other guys make out with their suspension arm mods.
