I'm wondering if this will work. I have the Futaba 14SG and it came with the R7008SB receiver. I know I can pair the 14SG to my stock receiver and have been using it that way. But I believe the stock receiver is limited to 7 channels. But it's S-Bus, so I don't know if that is strictly true. Is the stock receiver capability limited to 7 channels? So my next thought was to replace the receiver with the R7008SB. That has the ability to use 12 channels. The datasheet shows a mixture of conventional servos, sbus servos and s-bus2 servos. So this suggests what I want to do might be possible. I'd like to have 1) Standard sbus channels 1-7, like the stock receiver. 2) Two additional channels, using either the port connectors OR sbus channels OR sbus-2 channels, whichever is possible. My thought was to put the receiver in Mode D, and use channels 9-15 for some functions and sbus for the same functions as the stock receiver (1-7). My first question about the R7000SB datasheet is that it shows ch 1-7 and sbus for Mode B. Are the channel ports 1-7 controlled at the same time as sbus 1-7? Or, are they different? My second question is, if I put the receiver in Mode D, do I have sbus channels 1-7, like the stock Phantom 2, and channels 9-15, for other use? I was thinking it might be something like this: ch1: A ch2: E ch3: T ch4: R ch5: X1 ch6: X2 ch7: U ch9: Video switch ch10: shutter control Last question, for now, is if it's possible to use the R7008SB, to control the P2, just like the stock receiver, without making any other changes, other than replacing the receiver AND have some additional channels, what mode should I use?
