Bob,

I have another question about props. I know must serious aerobatic guys do not like Zingers. I had bought a MA wooden 22 x 8 for the first flights on my Giant Aeromaster and had good performance. I like the look of the Vess, so bit the bullet and bought a 22 x 8 and it was spectacular. At the same time I switched to synthetic oil at 50:1 and after a couple of engine runs and needle tweaks, hit 7400. Sadly, the Vess did not last the day, as I sort of "dorked" it in. Went ahead and re-ordered another Vess and, whoops, did it again. That's about $64 in props. Put the MA back on and you guessed it..dorked yet a third time. By now I am wondering if I have ever learned to land. Anyway, at the rate I am going thru props, I was looking for economy and ended buying two top flite power point, 22 x 10. I'm getting about 6400, but the plane seems to fly the same and the props were only $17 each. Higher pitch forces more speed on landing, and I have determined I am marginally tail heavy. This is a sport plane and does not really need the oomph of a DL with an exotic prop wringing every possible RPM out of it. BTW, flew yesterday in windy conditions and managed to bring my prop home without a scratch. Then again I aimed for the grass rather than the pavement.

I am going to have a fellow club member fabricate a steel nose hub for me. He will make it a little larger in diameter than the prop ring and will mill out four holes where the prop bolts will recess. Do you think hanging a few ounces (6-8) on the nose will have a detrimental effect on the engine? Bearings, crank, etc? Somebody cautioned against this, but I don't remember if it was this thread or another.

Thanks,

Greg
