Does anyone have a Pirep on this tach with Pmags ? I have tried MGL RV1 and EICommander and both were unstable in the last digit at cruise and the MGL wont read below about 1000 RPM. I will buy a T30 tomorrow if it is stable. Just a thought, perhaps the gear lash in Pmags, documented by Bill R, is the culprit and rock solid readings are not achievable ?
