I took a look in the box today, this is what I found.

The motor all up weighs 3 pounds 9.7 oz. ready to fly. 1636 g.

Carb is WT664A

Plug is L7T.

Ignition is RCCDI Version 2.0 4.8-6.0v.

The exhaust bolt hole spacing is 1.644" 41.75mm, bolt looks like 5mm. The exhaust port is .577"x1.051" with about 1/4" radius corners. 26.69mm x 14.67mm

The DA 100 header I have laying around fits perfectly, you can see all the threads of both holes, though I will dill the holes out just 1/64" bigger.

The muffler is a light aluminum thing that's painted silver gray.

The casting for the cylinder is gorgeous, like the MT62 great casting. It has five intake ports, one boost four transfer, and one exhaust port.

The piston is two rings and blocks maybe 2mm of the exhaust port when at BDC, maybe this cylinder is going to be used on something with a 4mm longer stroke?

The machining of the crankcase looks at least as good as a DA50, but not polished like a Brillelli crankcase. The crank is supported on both ends with what looks like one bearing in each halve of the crankcase.

The prop drive has a 10mm bolt tapped for a 4mm spinner screw, and uses two 4mm blots through the prop in addition to the 10mm.

The reeds are large, one on each side of the reed cage, the are translucent fiberglass, set at about 45* to the mixture's flow.

I have all of LS Pro's engines, this is the best made by far. This and the MT62 will make power with anything, no excuses that it's cheap. This looks to be a better made engine that my DL50, just super clean casting and CNC crankcase. I think this engine will blow everyone away when they see it in person, it looks better in person than the pictures. I can't wait to crank it up and see what power I get, I saw Larry's prototype engine and ordered mine right then.
