Hi all,

I'm an experienced glider and electric pilot and am now building my first glow model. I seem to be having some trouble with fuelproofing. The model is a Herr Cloud Ranger and I've got a Norvel .074 mounted on it. After running it for a tank or two... the covering around the fuse just aft of the firewall and on the cowl cheeks is starting to bubble very badly. I'm positive it's due to the fuel.

I glassed the firewall and inside of the cowl cheeks to add strength as well a fuelproofing. However... I just don't see a way to keep the covering from getting fuel behind it. Is there something I'm missing or is this typical?

Any help would be appreciated.

Eric
