actually, I don't think they did. I've tracked it back to the point where i broke a prop on an aborted take-off when a wheel caught and the Bolley shredded in the grass. I never saw one shred like that before, especially in grass!
The only other prop big enough for the 75 was a 14.5 three blade and I thought, "what the heck, let's see if the 75 turns this okay".
It seemed to, but about then was when the problems started and it took me a while to realize that I might be loading the big fellow down way too much. By then I had changed the tank, filter, plug, (the plug was giving a bit of a drop when the glo-driver was removed at the end there) and yoga. Somewhere in the middle of all that was when the new gallon had to come forth, but I'm pretty sure I had already had the problems before opening this current one.
My new Bolleys have arrived from my buddy Roger Wildman and I'm back on track to sort things out with "normal" numbers.
I put the power train in my backup Crosswind and will do the rest of my troubleshooting with it, but after the nats.
Thanks, Dennis, for your help and concern, I'll keep you posted as to progress, and hope to see you at the nats!!!
Blessings,
Will
