hyper 9 pro conversion

[Marvin]

You'd need a new chassis, battery box, motor mount and centre diff and mount. You could get away without the servo tray, as most seem to be modifying it anyway to lower the ESC. Just get a couple of servo mounts and a piece of carbon fibre or aluminium sheet and make an equivalent.

Conversion kit would probably be cheaper though.

You couldn't just get the Hyper 9E motor mount and mount it to the nitro chassis, due to the smaller spur, and that it has been moved around a bit.

Mike might be able to make you a mount as BL_RV0 said.
