Duane, I'm just sitting here planning things and I was wondering if you could post some photos of the inside of the fuselage with the radio installation? Also, another out of the box idea occured to me. The DuBro 24 oz. fuel tank fits behind the firewall just fine. The problem is that in order to mount itin the conventional manner I would have to hog out a substantional amount of former F2 or large areas of F6, so I figured that since the fuel doesn't know what shape or position it is in , in relation to the engine or fuselage, I could mountthe tankon it's side as long as the vent/pressureline inside the tankis in a vertical position pointing in the directionof what would then be the top side of the tank. I'm not sure how clear this explanation is, but if you get my drift, let me know what you think.
