like Bondonutz said, it comes with the losi e conversion.
turns out, my whole endbell was stripped from me overtightening. Thank God Castle is about to release the motor repair kits. In the meantime, i'm gonna use Mike's motor cover to suppliment my motor screws with my other builds. that'll be the long term solution along with the cradle.
i was chatting with someone here when they suggested Mike's motor covers. he said when he was stripping endbell screws, he bought Mike's cover, and he's been issue free since then. that was a huge relief.
we all should raise a cold one and toast Mike. He's always got great products to take care of us.
