As far as lipo power goes try true-rc out im running one its great has just as much quality as a maxamps at 1/2 the price.If you cant find a Neu motor check out Medusa v2 motors they are very close to a neu thay are just machine wound not hand wound but have tons of power, no problem standing up my X1-CRT on 5s (they would also make a great backup motor to a Neu)
