dont like the yammys they break easy ,started with a yammy 25 then wet to a trophy & now @ a tempest all 25 pitch, the trophy is grate for handling, mine drove like a go-cart but lost a few mph, the tempest gives me more speed. the trophy I had a BLOW-OUT ring(KPS http://www.keystone propeller.com) & all the holes completly pluged for a decent HS, my tempest has the factory 3/8 plugs in it i tink & hole shot is good.
