Ron,like Barry said you need a lot of air flowing through,here is a pic of my cowl i just finished and flew today at 90deg here in trona(just as hot here)and it ran nice and cool, it wont be long and me and you will be flying in 110+.

Kaos, if you insist on keepin the pants on (no pun intended)you can jb weld or 30min epoxy a washer just inside the hole to the inside of the wheel pants that fits the axle and it will keep from washing out the hole.

awe what the heck, here is some more pics


CeeGee,here is a pic of your idea to repair my lg,worked great,Thanks
