"DX8 RPM Sensor"
Can you use one RPM sensor with 7100R receiver and DX8 to give telemetry and limit head speed?

I used a Y-harness to get RPM to the Gyro and TM. It should work fine. The telemetry RPM works, but I am awaiting Mikados vbar gov update so I haven't tested that yet.V-bar

You can splice into you sensor lead or use these:

You'll need to disconnect the red (V+) wire from where it goes into the telemetry module. That will interfere with flight pack voltage sensing.

Don't you need the red wire for RPM. I'm plugging into RPM on the TM, not voltage/temp.V-bar

If you're plugging into the receiver and TM1000, it'll get V+ from the receiver.

jrb600n, how is your setup working with your back plate sensor connected to your receiver and telemetry module? Looking to do something like this on my 700.

I hate to admit this but I sold my AR7100r months ago and set up my vbar with satellites and have been waiting for the Gov firmware update ever since

I flew with no gov and used throttle curves for a while before my TM, but I did not like it and stopped.

So....I don't know. I do however get an RPM reading on the Tx when I spin the starter shaft on the engine. I'll guess I'll wait to see how Vbars gov works with the sensor.
