New buggy motor? (help choose)

[rootar]

well after im pretty sure i burnt up my 10xl for sure after the test tonight i decided i need to go ahead and get a good motor, this will be going in my xray xb8 with a MOD1 mm and 5s 5000 flightpower, this is gonna be raced in up to 20 minute mains and it should be no trouble because after it overheated and shut down 18 mintues into the 20 a-main over the weekend the battery still had 3.89v per cell left and it only held 2600 mah when i charged it. so with a better and more effiecent motor i doubt ill have problems with runtime.

IM AFTER LOW LOW temps thats all i care about is low temps and no problems out of it after i get it setup.


WELL nvm on the price difference the 1515 was sold i guess ill be buying new unless someone has a used one of either?

so 1515 for temps or will it really be TOO much.
