Ok.. The Magnum is ready for a second try...
New shaft and prop-adapter installed, and the APC has been replaced with a CAM Carbon folding prop, a 14x10 cut down to 9,25 inches... With a 52 mm centerpiece, the prop folds back along the cowling, and that should do wonders for the drag on this heavy bird after the engine is shut down, and the shaft will never bend again...
I hope to have it airborne tomorrow if i have my charger-problem sorted out by then...
A 14x12-prop is on backorder, and i hope to have a cameraman at the field tomorrow...
