IanJ - I see the TS LRS systems can support 12 channel PPM: Manual for Tx and rx System
However some new microcopter projects now support 12ch PPM for all sorts of usefull features
a SPECIAL PPM fixed out firmware is available on request, ask for this when ordering,
or upgrade the RX your self is also possible, using a serial port level converter.
Would it be possible to support this? I'm planning on building one of these soon and I'd like to have as many channels as possible. My intention is to fly with one hand on the joystick and one on something else to control a gimbal pan/tilt. I'll have to modify the joystick to have the throttle near my thumb or something but I'm sure it can be done.
