37 notes!, I suppose the kit will use existing holes from the engine mount for the battery tray so you just have the screw the adaptor plate on then the lipo tray.
then you just need to hacksaw the servo mount in half since you will only need one part for the steering or buy the lie down servo kit like I did,
