A base for holding a FPV LCD monitor kit for the awesome DEVO 7E. Quick attachment to the antenna collar. It is designed to hold a compact RX5832 receiver, a 3S 850mAH battery and a 5" LCD monitor. Originally designed for the DEVO 7E. It will also fit the Turnigy 9X with a little filing of the antenna base rings. Fits the Frsky Taranis without modification.Print one of each part. Assemble with three M3 nuts and three M3, 14mm thumb screw.

Receiver source: http://www.banggood.com/5_8G-600mW-32CH-2s6s-DC-Image-Transmission-RX5832-Receiver-For-Multicopter-FPV-p-985687.html To mount it to the Turnigy 9X, the antenna base rings need to be modified a bit. The DEVO 7E rings are oval, but the Turnigy 9X rings are round, with the same maximum diameter. You need to do a bit of filing to the front and back side of the rings to make it oval. Mask the area around the rings with masking tape to prevent any accidental marring of the transmitter. Take a flat file and carefully file the rings to match the profile of the mounting collar. Very little plastic needs to be removed.
