i have the same conversion i would make sure you buy the correct size battery there is not much room for longer batteries, my flightmax 25c 5000 4s batts fit very snug. i think you can just buy the motor mount from e-bay its decent but not the quality of mikes is nice, i have not had a problem with mine though, maybe think about buying a tekno battery tray for $15 like i did and you can use many different battery sizes
