Hey Rick no major tricks just the usual bearing blast. Watch the upper deck you can actually add belt tension depending how you tighten it down. Others have used WD-40 to loosen belt tension. I have not done this myself your mileage may vary. I think Madjack does I always used a real old belt. Glad the toothpaste worked on the EVO. You've turned into a serious Tamiya nutter now haven't you. TRF, Evo, EVO-S.
