Thanks for the link. I was looking around it and found my NIB MP Jet .061 PB is now obsolete. I need to build a plane to mount it on. It's still on the break-in stand.
The needle on it is closer to the prop than any other engine I have. I still have a pink patch on my knuckle to remind me of it. It was the coolest looking prop cut I ever saw, 25 parallel lines in a row. From the RPMs I could calculate exactly how long my thumb was on the tip of the prop.
