I fly down at Houston some, at Geo Bush with Bayou City RC,so I know what you mean when it comes to wind!!
Put those nylon bolts in & go with bigger air inflated wheels! Carbon fiber gear takes out the bounce on asphalt/pavement, makes it stick better. I did away with the two piece slide in gear, took out the outter fuse balsa & put in a solid balsa block with screws and #6 blind nuts. I got Super Tigre 90's in two Yak's. The Carl Goldberg Great Planes (CGGP) ones are heavier built & heavier than the Seagulls. Got a SV 26 gas in one 67" Yak that has 77" wings (839 in sq, versus 1139sq in). That makes it a very different flyer!!
