Folks,

I'm looking for a upgraded digital tachometer. The one I have used you have to hold 4 to 6 " away from the blades. I'm building an 600N PRO and I'm not getting that close to these blades..

Any Suggestions?

Thanks

Optical tach from Heliproz, I think they are made by Model Avionics called a skytach, best/safest way to tach a helo.

Thanks I'll check it out....

Is a tachometer a must have for an electric Heli like the TREX 450?

I dont have a Tach yet i just do the math and that close enogh for me and fly by feel to

oh i do have 1 for my planes but would have to be to close to the rotors to use it on helis

rstroup: For a beginner, no. Not necessary at all on a 450 IMO. You can just run a proven motor+battery+pinion+blade combo that you know works, and also assume you get headspeed roughly the same to what others report with the same combo.

However, if you want to set up a Govenor mode on your ESC correctly, you MUST have a Tach to do it.

Also, if you start to do any competing, etc., you will certainly want to know exactly what your HS is for sure

Thanks for the info......

I understand that for a 600N if the head speed is to high or if the Blade angle is to low (Flat Pitch) you can burn out the clutch while you are setting it up. The tack for my V2 just helps me take the guess work out of the equation. Its not a must but it sure helps take out the guess work!

I understand, for now I have enough on my mind. I have only hovered once, and I am finishing up rebuilding the head now. It is raining here so I cannot get out and fly until tomorrow.
