You will always get more "pull" with the correct size of 2 blade prop rather than a 3 blade. you say "50cc Greenley" but there has never been one that size, I assume you mean an SD Greenley, 88" span which was designed around a Zenoah 62. Built as per the plan there will be plenty of prop clearance for a 2 blade prop. I would suggest 24 x 10 for slippery glass gliders or 26 x 8 for slower draggy vintage types.
John
the smallest of the greenley collection
i think is the 88" span with slight mod
i was thinking of the ground clearance i had issues
i am not putting the wire under cart on
i using fg one i pick up at a swap meet about 1.5 in shorter
did think about adding bigger wheels to compensate???
24 x 10 to 26 x 8 range
if i go 25 x 8 or 25 x 10 would be a compromise and work across the both glass gliders and vintage?
thank john
