I use this for my speed runs and it is excellent product. If you couple with a Rx controlled switch - you can even select the point in flight you want the speed checked. Avoiding those erroneous dive speeds.
Easy to swap from model to model ...
But you must ensure that a) Pitot tube end is aligned direct into airflow, b) is in CLEAN airflow not affected by airframe turbulence.
Thoroughly recc'd ....

Yea I like it, simple, fairly accurate and if all you want to know is how fast your funjet is going this is the perfect thing to find out, because it installs without damaging the plane, weighs practically nothing and gives what you want right as you land.

FRSKY gps works pretty good to but its choppy and it doesnt log unless you jump through hoops updating firmware and when flying over 100 mph I am not taking eyes off my plane!

Bench tested so far and works great. Will be using a lot on the bench to test efflux velocity. Can be used as a stand alone unit running off 6v max! Displays highest speed during last power up. Very compact and lightweight. Comes with ~3 feet of silicon tubing. Great value!

Exelente funciona muy bien tanto solo como con el OSD.

cuidado si lo instalan en la trompa del avion porque se doblan los tubitos de bronce.
