I have been slowly building my new FT kit and thought I would point out a few things. These may have already been covered but I am not reading through 20000 posts. Screws are very tight going in when assembling(to the point I was worried about snapping heads off)and I recommend using a soap or other lubricant for threads. Steering post that retains bellcrank and servo saver needs to be checked frequently when tightening screw through chassis brace pivot for torquing of plastic that in turn binds up steering. Also found very small brass chips in diff housings that need to be thoroughly cleaned and blown out with compressed air. I went ahead and washed all metal diff parts in denatured alcohol to verify clean and assembled diffs dry to check for proper shimming of side and planet gears. I found plastic fingers on diff housing cap to be too long causing planet gears to be forced into side gear in diff cup when case tightened and causing notchy feeling and binding in diff. These fingers need some material removed for proper operation and no binding in diffs. Question, what side of the case have people seen failing under normal use, the deep cup side? This is as far as I have gotten but I will be updating as I continue build.
