Optical Tach is usually the best way.

Thanks Andy
I'm aware of the Optical Tach but I was interested in using the Telimetry feature of my new DX8.
Spektrum sells an option for measuring motor speed,but I would like to modify it to show rotor speed.
I'm told someone makes a collar that goes on the main rotor shaft that has a pickup for sensor but I can't find any info about it???
