Propeller washer - BT-43EIS w/10mm spinner bolt
I am installing a new BT-43EIS in a new Great Planes YAK. Propeller washer B (#FJIG6840) was included with the engine. This works with the 8mm bolt which was included. I am using the Great Planes spinner included with the YAK. The spinner requires using the 10mm bolt that came with the engine. There was a small 10mm washer included with the engine. The 10mm washer covers very little of the APC prop hub (front side). It's easy to get a larger "flat washer" at the hardware store for the 10mm bolt. Is a normal flat washer too flimsy? What do you recommend?
