- Miniature's Optical Heli
- TACHOMETER
Here's a tool that's extremely useful! Ever wonder how the
"pros" know exactly what the head speed is (rotor RPM's)
on their heli? They measure it!
The oldest tach for helis is this one, from Miniature Aircraft.
Simply have a helper sight thru the tach while you fly. By adjusting
the "Increase/Decrease" switch you find a setting where
the blades are optically "stopped" and that's the RPM
- displayed in the large, easy to read "RPM" window.
Includes protective case AND - get this - battery IS included
and installed!
The Display shows 4 digits (last one is always 0) and the
viewing window is slightly larger than the Model
Avionics unit.
