ORIGINAL: cmoulder

These props must be trusted for 100s of flights. The weight penalty is only a few more grams and the technique is straight forward so why not laminate the whole prop? It's a stressed skin that results in a superior product. This is the way I will make them from now on
Happy to hear that. They will still weigh less than 60 grams I would imagine.

I was looking around Mejzlik's website and saw that they have props in the 18x10 and 17x12 neighborhood, but I didn't see any weights and I don't know if the blades are appropriate for pattern.
Bob,

The first one we built fully clothed if you will, weighed in at around 64 grams before any finish work. Expect a couple grams of flash to be removed and some sanding/smoothing loss. Once sprayed with clear chances are it will return back to the 64 gram weight give or take.

The weight will vary a bit because of the weight variation in the original wood prop. These are accurately machined but the wood density is a variable...

Still, I'll take 64 grams over 125 grams all day long

The Mejliks tend to have fat blades in this size range which robs power.
