What your lookin for is a Hitec Eclipse 7 channel. It will do positve and negative shift and, any channel you want from 11 to 60. That means you can use any receiver from JR, Airtronics, Futaba, Hitec, Berg, FMA, etc. I have one but am selling it
due to I need $$$ to fund my Twist/.46 engine purchase. It was on Ebay but someone bought it as auction ended saturday.
On transmitters, don't sell yourself short!!! I have a Futaba 9C that I regularly use. 9 channels and it will store an infinite # of model memorys because it uses a module to store plane info. The 16k memory module holds I think 6 aircraft. You can get up to I think 512k of modules and use as many as you want.
