Is there any real difference between them? Are there any I should avoid?

Thanks

Some tachs are limited in the RPMs to 2000 or less (particularly the expensive optical units) - not much use to a Trex pilot. I use the hanger 9 digital tach (~$30) and it works fine outdoors.

the tachs that only go up to 2000 rpm can be used you just lower the speed and multiply x2. My minature air tack only reads up to 2000 rpm but if I set it at 1300 rpm it reads my rex running at 2600 rpm. Model avionics makes one that reads up to 2400 rpm. The airplane tache are dangerous to use on helis.

That tach will work with the t-rex and will read above 2400 if done correctly.

hi chaps
i bought one the othe day (micro prolux tachometer)but dont know how to use it to get a true reading.meaning does the heli stay on the ground,does one hold the heli by u/carage,do you hover about 1m off the ground and get your mate (not wife) to measure......
im only asking becouse theres no instructions that come with it.
thanks
lloyd

My Model Avionic's Tach goes up to 2800RPM which works great on these smaller electrics with the higher head speeds.
