Wondering if anyone else ran into a problem with the diff build. One of my out drives were binding when the inner washer and pin were installed onto the ring gear. I have a lathe so I took off a couple thou on the inner ring gear surface to free it up. Just wanted to mention it in case anyone else has a similar issue. IT could have been caused by the thru hole in the out drive being drilled slightly too far over. I didnt take any measurements to confirm if the problem was with the gear or the out drive. When I first noticed the binding, I thought it was two washers stuck together but it wasnt.

How are you guys finding the buggy's strength? Are the a-arms holding up especially in carpet modified racing.

My left rear arm seems to be binding way before it reaches max up travel and hits the limiters, as shown in the pictures below. Seems like the bone is going way too far into the outdrive... and I'm running the kit (62mm) short bones.
Anyone else having this issue, and is it possible I have something put together wrong that's causing it? I'm using Dustin's setup for droop measurements etc.

Check your camber. you may be to long on the hub pushing the bone back in. Looks like you have 4mm on the hub

On my kit, one front and rear arm shim needed a little sanding, and the rear side of one of the gearbox pinions, too. Other than that, it's been a great building experience so far! FYI I added the YZ-4SF RDRP aluminium fan mount to the wiki, perfect fit.
Edit: One more hiccup on my car: one of the pins of a rear drive shaft was damaged. Thanks to Ruddog's customer service, the replacement should be with me in a day or two, and I'll be running when the paint on the body is dry!
