I finally started upgrade project from APM 2.x to Pixhawk 2.4.8 on my DIY quad. While building the wiring, I realized that the Pixhawk does not support classical PWM inputs separately for each radio channel. Is this correct?
I have about 10 years old Hitec Aurora9 TX with Hitec Optima receivers, which don’t output either PPM or Sbus. FrSky seems to have some Hitec-compatible receivers (Delta 8) with PPM output, so this could be the easiest and cheapest solution to get the Pixhawk based quad flying again.
