Tim,

Its the differnce between constant pitch props and tapered props. APC produce the mass of there thrust in the first couple of inches from the centre and taper away towards the tip to control tip speed drag. This ensures overall rpm remains high. A constant pitch prop generate huge drag at the tip and can bring the overalll rpm down as a result. Ideal for big fat slow powerful models.

Looks fantastic erich. Like your linkages. Ill use that in my next project. Flew my pup last night till dark. Lovely. I must get someone to do a film for you and Tim. I managed to get it hovering into a nice 8 mph wind. Your 40fs will be fine up to 8-10 mph before it gets interesting.
