Opted to calibrate fuel gauge in “ground stance” position (~8° nose up) and with ethanol free 91 octane mogas. Set points was recorded every 2 gallons per Dynon setup instructions. Due to probe length and aircraft attitude, probe reads full above…
Aileron Rigging
Created aileron neutral alignment tool with two rulers similar to the one used for flap rigging. Set neutral position for RH aileron and centered stick assembly using digital level. Adjusted aileron pushrod length via rod ends then secured RH aileron to control stick. Repeated process for LH aileron. Verified freedom of movement and range of…
