The FrSky TFRSP can handle 6-8 channels via CPPM and then 2-4 SERVO channels for gimbal ops - very popular for DJI/3DR PixHawk FUTABA 14SG pilots who use Ch 1-7 for the Naza/Wookong/PX4 and then insert Gimbal inputs into pins marked Ch8/9/10 - TFRSP is compatible with the Futaba 14SG  FASST series radios.  The TRFSP is a Full Range Radio Receiver.  This C-PPM (also called PPMSum) is usable for reducing wirings to PARIS Autopilot UAV systems and also has a RSSi (PWM) pin as well - useful for PARIS v5 MegaOSD or PARIS AIR HERO v2 because you can access the first 8 Ch by CPPM single wire - then access channel 9 and Ch 10 for Alexmos gimbal tilt and roll.  Note that ch 1-4 cannot be accessed by traditional servos - only Ch5-10.
