While the high-end Futabas can do complex gear/door sequencing with programmable mixers, there is no dedicated/simplified function for it. I know some of the other brands have that.

We do have air pressure telemetry now (e.g. Carsten has a sensor sold thru ultimate jets), so if there were some way to use telemetry to control switches or mixers, you could implement all of this, including an air fail safe, in the radio. No such linkage of telemetry to control is possible for Futaba (I've written to them to suggest it!) .. but I think the Jeti can do it.

FWIW, my experience is that even if you could 'do it all' with the radio, you would need 3 channels for an F-15 gear/door setup (1- gear, 2-doors that stay open, 3-doors that open and close) .. add to that two for the canopy (1-open/close piston, 2-locks) and you've just eaten 5 channels.

Even with 18 channels this is a lot to give up since the planes that use complex gear/doors inevitably have other complex functions and you run out of channels quickly. I've just done an install with the Jet Central gear/canopy sequencer all in one box with an air fail safe, and it only consumes two channels .. but I would have no objection to using two sequencers like the one Gaspar is proposing as I mentioned in my post above to handle gear and canopy. I, for one, think he makes very nice stuff!
