If i just would replace the 40x75 2000kv 4-pole stock inrunner with a outrunner would a 42/50 840kv motor be enough ?

What's 40x75? What is 42/50 mean?

As far as what brand of motor you should use, check out Scorpion brushless motors, IIRC, the 40xx S2's are the newest (not even sure if they are out yet) and have been designed with the best high temp. magnets, high temperature wire and small mil core material thickness (0.2mm stator steel). These things are very efficient and just as important, they will be tough.

The innrunner motor i 40mm in diameter and 75mm long and thenoutrunnr is 42x50mm
(the stator in the outrunner is 35mm in diameter and 26mm thick annit has 12poles )
