Post subject:  Viewing of low RPM's in software

Is it possible to make it so very very low RPMs can be viewed in the Spirit software or via Jeti telemetry to help with governor setup?

What would be ideal is to be able to turn over a Nitro engine using an electric starter and to be able to see that the sensor is reading correctly just by the starting speed applied.

No low RPM's can be viewed at the moment on my setup so bench testing of the sensor is not possible.

After further testing earlier It does actually seem that I can see the 600-615 RPM displayed on the TX from turning the engine over with the electric starter.

I have had the sensor out and tried it with several sensor to backplate spacings.Seems to work actually touching the backplate and also quite a few mm away.
I've settled for 0.8mm of a gap.

As long as the governor sees over 40% on the TX it shows what it should do so looks like no issues with this and I can actually check the sensor is working on the bench without running the engine.

Don't know really what the lowest value is that will be displayed but this is good enough to confirm the sensor is picking up the crankpin OK.
