Devo 10 Receiver for QAV250, which one?

Hi Guys
I buy a couple parts for start a new build style QAV 250, I want use my Devo 10 untouched yet
Which receiver will be interesting for drive a cc3d ?
I'm a little bit lost, too much choices, if i stay with walkera receiver no need modification, what benefit except the price if I used another receiver ?
Regards
Vic

The rx702 has longer antennas if you wanna go out further than you could with the smaller rx601. With zip ties and shrink tubing you can make nice holders for the antennas on the 250. If you have the devo 10 white you will have plenty of range.

On a 250 I am using a rx615X (DSMX) with CPPM to the CC3D. No issues so far.( no FPV)

Finally I would like used my RX703A receiver from my scrap QRX350. About the connections with a cc3d, I don't find any information about the protocol used with this receiver.
Can I plug it like a PPM receiver ? in my QRX350 only one plug (3 wires Black, red white) was plugged in the DATA BUS to data bus DEVO M !

The CC3D works with S-Bus, DSM2/X satellite, PWM(separate wires), PPM(CPPM /one
signal wire). So it will work with you rx.
