I like to monitor voltage in two places - the receiver has an internal voltage sensor that tells what the operating voltage is of the flight control system. On any heli I like to have headspeed, with pistons I like to have engine temperature. That’s my next investigation to see if the FrSky radio system can actually be made to be usable with gas engine aircraft. The N2 Industries mini hub might actually support hall effect rpm and temp with the old TEMS-01 sensor. FrSky has no support for rpm, except electric. ArduPilot has no support for temp sensors. With gas engines you need rpm and cylinder head temp. I modified a XSR receiver to get the uninverted signal from the driver transistor on the SBus circuit but it still doesn’t work. FlySky, with FS-iA10B receiver uses SBus and it is supported by Cleanflite but so far can’t get these sensors to talk to the Smart Port. I’m trying to get some FlySky sensor modules to work with the Smart Port on a X8R. Helicopter engines run 10,000 to 14,500 rpm. They have the Gas Suite but it has an in/out for CDI ignition and only measures to 10,000 rpm.
You’re talking about a generic sensor hub with support for “dialects”? HOTT,IBUS,SBUS?įrSky does not have any decent magnetic pickup/hall effect sensors for headspeed on gas helicopters.
