Hi Greg,

Yeah its worth a try with the 12.25x3.75 and worth a go with 11x4, and 11x5 too just to make sure. Still reckon the 12x4 will be best though......You could try wooden (Zinger here in UK) as the spool up is slightly quicker than APC. Only problem is they're very fragile. When I was learning to hover I bought my LHS out of 11x4 Zinger props in less than a week!
