RE: Bragging about the .55 AX
I"ve lost count of the .46AXs I've helped break in. I chuckle to myself every time another guy brings his new plane with a new engine on it for me to break in. Word is I'm supposed to have a touch breaking in OS AXs. lol..... I do have a secret. Do it like the book says do it. And I don't know a one of them that's given any kind of trouble. Maybe half of them show low end rich symptoms after a couple of weeks. That's it.
And I got 2 .55AXs and a .75AX. They run just as good. Can't say they actually have anything distinctive that sets 'em apart other than the extra power.
One thing I've been noticing over the last year is that as a group, they all seem to have a better range of props they spin "best". Years ago, you'd often see engines that were persnickety and favored a fairly tight range of prop. These seem to be happy with way more than just a few favorites.
