Steve, I am flying the 2m. Gerasis Fox at 45mm back from the leading edge, and it does just fine. I would not, however, want to go back any farther than that. Try 40mm as Neil suggests below, for starters. BTW, I put "armpit" towhooks on mine, directly on the CG and maybe a quarter of an inch below the wing lower surface, so I could use a bridle on the winch. Works famously. Beautiful climbout, nice round-off on the top, and an easy release. Better let go smack in the middle of a thermal, though, if you want to keep going up, since the little guy is not exactly a light air thermal hound. I'm tempted to try aerotowing it at the Ellensburg, WA event next weekend. >Hi Steve >>I have a Gerasis 2 Meter fox and have run into a little snag. >>I DO NOT speak Czech! anybody know where the Cg should be? The airfoil is said to be an RG15 but who really knows!!. >I don't speak Czech, but I did write a review on it for the UK Silent Flight Magazine >(Sep/Oct 99) :-) >The German instructions quote 45mm from the LE, I would recommend 40mm to start or >maybe even a wee bit less.
