Does anyone has experience using this material on F1B’s?
It’s 1/2 oz per square yard.
Do you feel it could be better then polyspan?
Thanks a lotUsually the F1Bs need some ballast to get them up to minimum weight. I think the light weight rip stop nylon material would be ideal for maybe center panels.
I have found this information about different covering materials weights.
Beying so used as Micafilm is, I’m surprised that the colour one is heavier then Icarex.
Any comments?Covering gm/m²

I think the Icarex 31 is 31 grams per square meter. I still prefer Polyspan for wings. Easily patched and if painted using FAI Supply’s dye, no weight gain by adding colors.What really matters is the weight of the covering after it is installed. That finished weight includes the adhesive and in case of the Polyspan a big percentage is for the dope. These are my net weights (1st number) and the total weight (2nd number) in g/m2.

Polyspan 23 40

So it seems that Mylar will be a good option, being waterproof and very resistant.
Any special tricks to cover with it?Pedro,
To adhere Mylar to the structure I use Velcro Adhesive. I put a small blob of this clear contact cement in a small mixing cup and thin it with M.E.K. (Methyl Ethyl Ketone) and brush it onto the structure. Another good adhesive available in Europe is Pattex Transparent made by Henkel – this will yellow a bit after some time. Use a small sealing or a trim iron to adhere the mylar. Use the iron to shrink. Mylar will shrink quite a bit – the clear more than the aluminized. Your structure has to be strong or you have to be very careful when applying heat. These adhesives are also great for covering with Micafilm and Icarex. Icarex by the way is the most puncture proof covering material.
