prop size for Hacker 20L
I'm converting an old glider to electric power. The only spinner that would fit properly needs Graupner 8mm yoke blades, and finding them in the size range I need is frustrating to say the least. All sources seem to be backordered. I was planning on using a 9 x 6 prop, but the only thing even close that's currently available is an 8 x 5. Will that be too small? I'd just like to get this plane in the air before the end of summer; not so worried about performance as long is it will work without over-reving the motor. Thanks
