Default RE: Tachometer Placement on Gas Engine

ORIGINAL: blueberry

I am new to using a tach also I have the tower hobbies mini digital it was also reading very eratic until I put a incandescint light on the opposit side of the prop aimed at the engine.
Now I get very steady readings. Don't use flourescent as they cycle 60 times a second
your tach will read 3600 rpm soo it may affect your readings below that. Give it a try.

An incandescint light also cycles 60 times a second if its powered from the ac power. Use a flashlight.
