I am a newcomer in the engine governors world.
How critical is the distance between the sensor and magneto?
Calibrating and setup - no problems, in static bench mode everything works (green light diode in different modes etc.) as it should. When I turn the fan and the magneto passes the sensor the red diode lights up brightly. The distance sensor - magneto is exactly 1mm (0.039").
Yesterday I hovered my heli at a rotor speed 1700 rpm without the TJ engaged. I then tried to engage the TJ, which was set to 1550 rpm following Modelavionics setup charts, and nothing happened. I suspected that I could have set the desired rpm too high so that the TJ could not engage/catch-up, so I tried to get the TJ engaged by ascending rapidly since I know that with this heli the rotor rpm rises approxemately with 200 - 300 rpm (I change to more max.pitch later). No engagement, the rotor speed went up and then down again when I stopped the ascent into hover. I did this several consequent times but no...
