Well, I'm about a third of the way through my build of a FT and its been fairly smooth.
I had a small washer missing for the servo mount, no big deal, and found some glass like grit in one wheel bearing which I got out with tweezers and motor spray.
The gearbox case halfs aren't particular flat and I'm guessing that's from where they land and cool when they get out of the mold. It's caused a little bit of tightness in the diffs but I'm confident they will become smoother with use.
Really enjoying building it so far.
Ordered my ESC and 4000kv Tenshock SC411 this evening as well.

Parts are still very scarce of here, I can get arms but what I really want is a front spring kit to put on the back but no shops seem to have them so I may have to order from the states.
Amain ship to the UK right?

Keep the helpful tips coming guys.
Cheers
