Dany,

I did set up a Skymaster T-38 just they way you and Steve are describing. It is a smaller, lighter jet so this seemed like a sensible approach. I used all stock S-bus gear from the usual suppliers (Tower Hobbies here in the USA), and dual A123 packs each with its own switch, and both switches feeding the RX directly. No buffers, powerboxes, etc. Worked out very nicely from an install point of view. I did use heavy (but "stock") servo extensions to take the one SBus line to the tail to feed the two elevators and the rudder via a 1:3 splitter, and it is nice to only use 1 wire per wing with a 1:3 splitter feeding the aileron and flap servos. Used all standard (not SBus servos). Caveat .. the plane is pretty much done but not yet flown :-) Sounds like Steve(kott) has many planes done and flown this way, so I'd rely on his experience.
