I've installed it on a Walrus, on the canopy, pointing the propeller's blades.
I've tested it in my room and it worked perfectly, then I tried it outside, under direct sun light, and it didn't work at all.
I had a hook and loop stripe on the canopy, so I was able to test different distances between propeller and sensor and I've tried from 5 cm till 15 cm, with steps of 1 cm, but during flight I had no RPM data.
When I landed the plane, I tried to make shadow with my hands and it looked to work in some way, but if I left it under the sun, 0 RPM all the time!
I'm totally disappointed about it.

Superb item to use in all RC gear. Cheap but top of the line system like Futaba. It just works. Buy with confidence.

Easy way to check thr rotor RPM, but you should be aware the it is out of viewing range of the flybar, I mounted mine on the tail-tube. Easier at FBL helis. Not to be used at home with illumination switches on, because it shows the mains frequecy( 3000RPM at 50Hz b.e. ). A small piece of tube put on the sensor makes better resistance to daylight distorsions. Good product.

Good sensor to check rpm on motor in flight. It's light and works very well. Have it attached to my sensor hub that goes to the digital port on the receiver (not the analog ports). Check frsky website for documentation on the refresh rate of this sensor and other technical details.

Optical sensor which should be placet just behind the propeler. Works no problem with diferent numbers of blades. Other than that there's nothing much more o say about it. Good product.

installed on Raptor 30. Works great. I didn't realize I was flying at such a low rotor RPM (1300). I modified the throttle and pitch curves to get a hover at about 1650 rpm and it was much more stable.
