no worries mate
I like to think that im not a "monkey see, monkey do" type of fella,, but, I have noticed that Al has been using the stuff on a number of his body configerations for the last 7-8 years now, and me thinks that is sortta saying something,, I have also done resurch and it appears the small airplane crowd recon its worth mph
