Hi Ramcharger,

Thanks for the reply. I think I can help you a little with yours. I'm not sure if there is any difference between the Great Planes version or the Lou Andrews version.

Regarding the fuel tank and lines. I had to use a Sullivan 14 oz. fuel tank that is shaped flat on the sides and rounded on top and bottom and install it with the rounded sides up and down. I also glued a piece of pipe insulation that I had cut in half to the front of the tank so that when I installed the tank it would keep it about and inch or so from the back of the firewall. This kept my fuel and vent lines from getting kinked. There was then ample room to wedge 1/2" foam between the sides of the tank and the fuse. Then I simply used a piece of balsa tack glued to the sides of the fuse to prevent the tank from slipping back. I am sure my tank will not move at all.

Regarding the CG with configuration 3. The instructions stated 3/8" in front of the rear cabane for this configuration. I doubt a half inch will make much that much difference, but the elevator might be a bit more sensitive.

The cowl was a pain in the butt for sure. I built this one. But I had to cut my own stringers because the front and rear formers were slotted too large for the recommended square stock that the kit included. Then I just wet the balsa sheeting all the way around and taped it in place until it dried. Then I used auto bondo to smoothe it out and then sanded, primed, and painted. I then used automotive clearcoating for the plane and cowl to give it the shine it has and to keep the trim and seams from lifting.

Don't hesitate to ask me about anything else about this plane. I will be glad to offer any insight I can. Good luck

Jeff
