Sonex 0861 has completed the phase 1 requirements and is again released to the wild. I did the time to climb and stall series and found the stall to be the same at 42 mph at the new gross of 1150#. Vy was 790 fpm at 80 mph. I think the actual climb rate will be better when I can get the "ballast" to run the clock and take the notes on the data while I just fly the airplane! I finished the required flight tests on Saturday but the weather has not cooperated since. Got the ignition dialed in today but just a ground run so far, true test is a flight with the electronic ignition off to see if there is a temp drop. Regardless of where the numbers sort out I think I'm really happy with the upgrade. If I were building at this time I would definitely consider the Turbo upgrade. If I already had an engine that was normally aspirated I would lay out the firewall for the Turbo upgrade, cause you know you're gonna have to have it!!!! This is the best thing to come along since I bought the plans!
