Satinet, I am losing more than a scant 10 grams, I ditched 20 on the wire harness alone. In all the work, I will save ~50grams, and ya, that aint much I know. But since JR is nice enough to support me and soaring here in the USA, I am going to support and advertise them on my ships. And you know, last year when I won the National Champiopnship in Unlimited class sailplanes, that same vinyl was on that ship too.
Yes, you might be able to see a statistically insignificant bump on the lift curve, but I can screw up a flight a lot easier all by myself
