They are suitable for engines 60cc to 150cc and the screw holes are perfect fit for the Walbro carby holes.
Only US$ 6.62 aluminum or US$ 1.90 plastic.
Have attached photo of my blue aluminum one on engine.

A local gunsmith bored the hole to match the biplane props. Luckily he had worked with carbon fibre before and had no problems.
Definatly improved the performance. I used less fuel in 1.4 hours tonight as I normally would have used in about an hour. Climb rate increased about 75 ft/min.

HELL YES!
nice find! post some pics of the mods you did to mount it to the cranks to complete the thread. always good to see cutting edge tech welded to a lazair.

Very little change in carb tune, just a touch richer on the highspeed. Both engines now peak alot closer than they did with the biplane props.
Peak RPM is about 5300 which is what the prop calculators predicted. Not much unloading in the air.
I'll have to fly with the GPS to see how much the climb rate has increased but it certainly seemed higher.

Mejzlik props are indeed hollow with a solid carbon fibre hub. I am not terribly concerned with what they do if they hit something as any prop strike is uncharted territory regardless of prop design.
I wish I still had the picture of it but what sold me on Mejzlik props was an engine failure I witnessed.
One of the large scale model airplane guys at our local club had a crank failure due to a manufacturing defect in the keyway on the engine. The prop and remaining part of the crank tore through the cowl then passed over the wing and tore some rather substantial chunks out on its way.
We went looking for the prop after the plane was safely back on the ground and we found it with one blade embedded into the ground up to the hub. To get the prop out of the ground we had to rock it back and forth a bit to free it from the hard clay but it came out. The prop didn't have a mark on it.

With a set of blade covers and a polo shirt it was still under $180 a prop. If you didn't order the extras I did it would be under $150 each after shipping.
Very light weight (~350 grams) and only 8 grams difference between props.
Had a local gunsmith/machinist bore the 5/16" and 7/8" holes. he made me a drill guide for the 5/16" holes if anyone needs it.
