Hi Fred, do the ECS driveshafts wear out and require complete replacement or are the wear parts easily purchased at a cheaper rate?

Is 50mm what you use with the NT1 gear different too?

Here is what I see when trying to adjust the rear motor screw. The button head screw will not fit through the the large hole on the 96 spur gear and I don't have enough room to insert the driver to adjsut the rear screw either.

Am I missing something?

Ok, I figured it was something like that. It's clear the car was designed for mod racing. Their spur gears have larger holes and allows them to adjust that rear screw.

Hey Brett, eventually the parts do wear but of course wear is a function of how much power is run in the car. Even in mod I don't replace parts that often. Yep all the parts can be purchased separately. With all the current gear diffs available we have to run 50mm shafts...for the moment.

Our you can open that one hole up with a reamer or drill. Just go in and make the opposite hole the same size to keep it balanced. This is what I have done in the past. Your taking so little material off you probably dont really even need to do the opposite hole but I did anyway.

I've simply gone to using a 2.0mm ball end driver for the rear motor screw.

17.5 non-boost (or VTA) is probably the only class that would have problems. I run 17.5 boosted with a 114 spur and no problems at all.

EA thanks for your suggestion. I was thinking of doing the same thing.

Not sure how this helped, unless the 2.0 screw is smaller. What size is the screw?

He means using a 2.0mm wrench that has a ball tip instead of straight. It allows you to use the wrench at an angle.

Ok, I understand now. That's another great option. Thanks for the feedback everyone. Looking forward to putting some laps on the new car!

Does anybody have a good source for ceramic diff balls and thrust bearings for the Xray diff? Within the United States, preferably.

The diff balls are 2.4mm and the thrust is 3x8x3.5mm.

Thanks!
