Hi Guys,

I know of these 4 different brands of optical (viewfinder style) tachs.


Kyosho "heli blade tachometer" $149

Kyosho "syncro meter 2" $159

Miniture Aircraft "X Cell" $149

Western Robotics "Chinook" $149

Model Avionics "Sky tach" red $109

Model Avionics "Sky tach" blue $89

I had a "light sensor" tach some years back, (Glowbie style) you can place it on the ground and hover over it or you can tape it to the tailboom.

both ways worked for me with no safety injuries ....[8D]
