I just received mine the other day. First thing I did with it was swap out the stock motor and ESC with a Team Losi Exceloron(sp?) ESC and 6000KV motor, a 1650mah LiPo. I tried using the stock radio and receiver, but they dont work so well with the new ESC which sucked. can't reverse the throttle input, or at least I couldnt see a way to. So I tossed in a receiver for my Futaba 3PM. Also, I installed the Team Losi alum. shocks for the Mini T.
Aside from a front link end popping off the ball which is apparently a common problem for the Mini T and Mini Desert Truck, this thing is a little tank! I'm used to my baja which is prone to breaking if I mistreat it. Not my Desert Buggy. it takes a lickin' and keeps on tickin.
So far my only complaint with it is the diff, which in stock form is a gear diff and very "loose". The first thing I intend to buy for it when i get to the states is to see if theres a ball diff or a sealed gear diff for it. I also intend to see what Aluminum Mini T parts are compatible with the Desert Buggy. Definitely wanna make this thing bling, which I dont normally do.
I still look back and wish I had bought a RC18B, but I dont regret getting the Mini Buggy. its a blast!
Anyone know of any good Mini T/DT/DB resources?
