Hello, RC friends!

I have a Sanwa 12S RS and an RX461 receiver. I bought it to use with my nitro car and to measure the voltage of the LiPo battery and the temperature of the motor. I also really like this controller.

The problem is that I can't find any more receivers and I don't understand the temperature sensor. I think I can replace it with a 10k NTC thermistor. Does anyone have any information? Or do you know if there are any commercial receivers that perform this function and are compatible with my controller?

The RX461 temp input likely uses a 10k NTC, so your idea should work, but accuracy depends on the thermistor curve (B-value). If you have the original sensor, measure it at room temp to confirm. Sadly these receivers are getting scarce, so if you need backups you may want to grab any RX461/462 you find used. Let me know if you want help matching the thermistor.
