Hopefully it will perform well this weekend as it did in it's first few races. My 94145 servo was having a problem with loose gears so I pulled that out and dropped in a JR3025 which is a little bit slower but smaller and lighter so that will help reduce the front tire loading. It also gave me room to run the servo wires behind the servo on the chassis instead of over the servo. Next I noticed some binding in the rear pod...it wouldn't droop under it's own weight so I tore that all apart. The rear links had a tad of bind in them that I fixed but the problem turned out to be in the shock so I rebuilt it with lighter oil...but the problem still persisted. Further investigation showed it was the rod ends on the shock. I had been using the cotton method to take out the play in the rod ends but on one of them I used too much and it was causing a bind that was effecting the whole pod. The rod ends were replaced and the new ones are tight enough to not need cotton. Lastly I noticed one of my motor wires felt like it was going to break off so I re-wired the ESC. This time I ran the motor wires along the left side trailing link into the lower part of the rear pod where they turned up to solder on to the motor tabs. With the wires this way the rear pod seems to move very freely. I've got a new body mounted and cut on it now...just waiting for painting and she's all set.
An old trick for the side links is to put some very small O-rings between the clamp part of the rod end. Thread the screw through the plastic clamp sandwiching the o-ring and tighten down slightly. This provides a smooth but tight feel on the links. Any Mx2 drivers wanting some of these o-rings, shoot me an e-mail to [email protected] with your address and I'll get them out to you.
