It's probably flown more than any L-4 did in WWII, but hasn't been shot at as much. I'm not really sure just how many flights it does have, but it's flown at least one flight every month since I built it, and some days gets as many as four tanks of fuel through it. My .65 is starting to sound as though I might be losing a bearing; there's no resistance, tightness or play in the crank, doesn't knock, and it pulls as well as ever. I have another one new in the box, but hope it will go on another plane.

ddrake, here's my inverted installation, note the muffler type I was talking about. I had to heat and bend the elbow a bit to get the exhaust to exit the bottom of the cowl, this was before that "button" style elbow was available (special order). The brass tube that runs down the left side of the firewall is for the crankcase breather The engine mount is a DuBro antivibe mount.
