RE: prop

What size engine is this for ? You are aware that going from 2 to 3 blade, you drop one dia. size and up one in pitch ?
Only ones I know of anywhere close are the MAS and Windsor 9x7 for a 40 size.

RE: prop

Upping 1" in pitch will put a greater load on the engine. In most cases, one needs to "reduce" the pitch by 1 or even 2 in addition to dropping the diameter.

Doug,

On their site, I didn't notice any 3 blade pushers that cpbpilot requested.
