I have been working on the Seagull Zero for two nights now and it is going together very well. My question is that the supplied fuel tank has a lip on it and I cant seem to figure out how it is to fit fully in the hole. Also I have never built a plane with a cowling and can not figure out based on the manual where the four wood blocks are glued on to attach the cowling. If any of you have built one of these any help would be appreciated.

Thanks Motor
