Hi all, I don't consider myself an expert on the Phantom 2, so I need some advice. Being an electrical engineer, ham, etc. makes me want to add a lot of 'things' to my Phantom. Ideally, I would like a absolute minimum of 10 channels, but I would prefer more. I recall reading that the P2 has a receiver with some unused channels. But, I might want to swap it out, for a higher channel rave later. I can't afford a Futaba 18 channel transmitter. I do have a Futaba 9Z, that I converted to 2.4Ghz, but I don't know if it would be compatible. So, what are some good, high channel transmitters that will work with the factory receiver. Second, any suggestions on a transmitter and receiver for even more channels. I think there are at least 4 unused channels on the P2, but the factory supplied transmitter can't access all. Hence, my looking for a new transmitter. p.s. I did search as I thought this would have been asked before.
