I have a megatech merlin which has been around the house for a number of years and never flown. I now have it together with radio trimmed. I need to put the prop on. I have an extra drive shaft , prop and a total of four nuts. One side of the prop is recessed for placement of the nut. The drive shaft is mounted. In what order do I want to mount the nuts and prop. What placement should the recessed portion of the prop be. Recessed close to the plane or far away? Any other suggestions would be helpful. I have a flight simulator, I can drive boats and cars well.
