RE: your opinion on micros?
the micros you mentioned in post 1 are 1 36. I have a micro dt and a micro-t. I did not do to many upgrades yet because the cars are so small I dont like to mess with them much. If you end up buying a micro you must put on threaded axles and bearings. I did the lipo power with the micro-t. I think you would be better off with 1 16 or 1 18.
