RE: Great planes ultimate 160
Anyone running Pro-Zinger 20X8 on the Fuji 43 with the stock spinner & bolt? I got my cowl on last night and assembled the prop/spinner and I only get four threads into the engine hub! That's kind of on the hairy edge of not enough IMHO. I checked the dimensions against the Fuji site and it is the proper bolt. Must be the Zinger is thicker than normal?? My 18X6 props are only 3/32" thinner, giving five threads, not much better. I'd be happier with 3/4" of the bolt threaded into the hub.
