Just ran my truck for the first time yesterday. Not too bad, I have some tweaking to do to it but it's not to far from where I want to be.
I modified the outdrives front and back (mentioned some pages back) to allow for greater up travel without damaging the diffs and it worked out great. I only need one 2mm rubber spacer on my shock shafts in the rear right now and two 2mm spacers in the front. Here's a
link to another thread showing what I'm talking about.
Another mod I did was to tame the steering down on this truck. Most cars use a lot more servo travel than SC10, most around 120 -140 on the radio's endpoints as opposed to 60-90 on the SC10. This means the servo is losing some mechanical resolution and makes the steering lock to lock very fast, too fast for me. To get more resolution I used a shorter arm. Here's a drawing showing what I mean.

My endpoints are now around 140 and my steering is definitely not as twitchy as some of the other SC10s I have driven with similar setups and electronics.
Here's some pics of my truck as it sits right now. It's currently underweight, 5.3 lbs or 84.8 oz. I'm not really liking the Sidewinder and 4600, I think it's too much for the ESC to handle, it lacks bottom end. It's all I had to throw in so I figured I give it a try. Because I have some room to play with weight, I'm going to instead put in my Castle 3800 SCT and a MMM. Should never have any problems with that.
And here's my current setup sheet, it's pretty accurate.
Feedback welcome!
