New Graupner 3 blade props
Graupner have got some new 3 blade props that I have only recently found. See
with some handy sizes such as 16" x 10" (40cm x 25cm), 16" x 12" (40cm x 30cm) and 18" x 12" (45cm x 30cm).
They also have some even larger carbon props at higher prices.
I was wondering if anybody has tried any of these as they would seem to be ideal for the SP range of engines, or if RCV would test them to check rpm ranges etc as it would be good if the range of recommended props could be increased. APC seem to be reducing the range of their mutli bladed props at the moment.
