inflight unloaded RPM
pcm
We are currently testing our pre-production onboard tachs. One of the test planes is the new Hanger 9 Alfa trainer. This plane has a 45 size engine. For a more realistic test, we removed the three blade prop and installed a APC 11-6. Turns 11,510rpm static. Unloads to 12,900 in the air with a slight 10 degree dive. This tach holds peak rpm in ram memory untill the receiver is turned on/off again. Also shows your receiver battery voltage to the 1/100 of a volt. Weighs approx.1 1/2 oz. Info and pics will be posted on our website in a couple of weeks. Ask any questions.
