Hello Guys,
I would like to comment that there is a very useful device manufactured by FIRMTRONICS ( www.firmtronics.com/rc-products/digimix-3.php ) capable to mix, procesing and conditioning signals from receivers to servos. It has three channel inputs and two outputs to servos; these outputs can be high or low rate pulse: DIGIMIX 3.

You just need to have some knowledge of basic or pascal program languages; language C is the ideal. The device is a little electronic board as you can see on pictures. Tipical applications:
V-Tail Mix
Gyro gain control
Two servo control with one Rx channel
Mix two Rx channels with variable rate following a third channel
Lights control
Servos sequencer
Another special projects

This device can give a valuable help on your jet planes. I used to mix different signals from Rx and gyros, combine retract and brake with one channel, etc. things that you can not do if you Rx is full or you need some control feedback inside the plane as gyro does.

The device come with a link to a webpage to download pre-rutines to make easy the device's program work.

Check it out.....

Rick.
