The engine is going on a Midwest Extra. The plane is almost ready for it at this point. The plane was built with pain-staking effort to keep it light, with alot of carbon-fiber(no fiberglass in this bird). I don't have figures on the weight total weight of the engine and components just yet, but will report back with them as soon as I get them. I'm using a 1400mah battery for ignition, as this should leave plenty of room for a day's flying. Break-in oil is Lawn-Boy Ashless at 40:1 for the first 5 gallons. It's not going in the plane until it has a gallon through it. I'm figuring that's about an hour and a half of run time, which it should be very consistent at that point. Even at this point I'm very impressed with it, and how easily it starts. The idle is something to behold. It almost seems you can count the R's of the prop.

Right now I believe they run right around $500-525.00. The stock muffler runs $49, and the upgrade Pitts(which is what I have) runs $99. It's said to swing a 22" prop very decently. I'm using a 22x8 for break-in.

Not sure if the crank is the same or not on the 44. I would imagine it's slightly different because the jug is integral to the case, and with the 50 obviously bigger, the case is probably different.

I've checked into getting a 44 for another plane I have, because they can usually be had for a few hundred less, as this seems about what I've found on the used market for these. That is "IF" you can find them. I'm usually late finding them and they are sold. Sellers have no problem selling the 44's, and they sell very quickly. I now know why.

I will keep posted here on progress, weight, and anything that might arise with the engine. Thanks for looking.
