I am from Greece and i just purchased a used Avid Flyer Mark 4. I am about to strip down the fuselage and inspect the wind for any damages and wear. I concern for the screws, bolt and pins, especially those which hold the wings in-place. The aircraft is equipped with a Rotax 912 (80hp) but probably i will sell it out. The main idea is to fit a Turboprop on it and run some tests. I will appreciate to have some tips from experience people on this plane.
