One of the most controlable motors for a micro are the Beast series from one18th.com but they aren't the fastest but they are one of the most controled fast motors I used in my old Micro RS4. I have since given up on the Micro RS4 and I am awaiting the RC18T, Hopups already bought are the Mamba 5700Kv, 7.4 Li-poly 2450mah battery, some GP1100 from Team Scream, Losi Titanium Turnbuckles, Hitec 81MG and Trinity Crome Wheels/tires. Now I can hardly wait..........Shoudl be the fastest little backflippin' Truck out there.
Hope I was able to help.
Also I haven't personnally tried the Trinity series but hear good things about them and I will get one for my 18T so I can race it Legal like.
