I had this happen at the weekend, and Adam knows about it.
I can't believe people are moaning about a slight change in shading.
Who cares as long as the car does the job its supposed to? You can't see it on track anyway.
I'm using the kit drive pins, and have had no problem what so ever......queue wheel failure in the next run! lol I think as long as the pin is central in the axle then it isn't a problem. I lock mine in place with threadlock to stop them moving.
1) I found these in the bag, they'd come off the sprue.
2) They know about this and are looking into it.
3) As above....
4) As above....
5) Not had any problems, was the fit ok or did it go on very easy? Are the servo spline in good condition?
6) Just excess grease leaving the bearings.
Basically I've run the kit 'as kit' with no modified parts or extended drive pins and have only had the problem of the turnbuckles moving, BUT, it did have a few side landings as the car flipped over, and this probably caused them to push in on impact. So the moral of that story is...don't crash, which is what I did for the rest of the day and they were fine.
