I have a Blackhawk double Demon Kit. I will be using a Brodak BH-539 likes it states on the box. I know some people use epoxy and silicone to attach the tank in place. Just wondering if these are the best options out there. Thanks.

Made a mistake on the tank, BH-596

                I built the Blackhawk Demon myself. I thought it was a fun airplane to build and the fits were very nice. I elected to go the bladder route and installed bladder compartment made from a cardboard tube from the roll of paper towels. This was a bit challenging due to that airfoil not being very thick and I wanted good fuel capacity. My concern initially with the tank in which I had problems like this before was getting the tank height correct to the engine. Once you've glued it in your committed. DO you drill  a hole through the leading edge for the pickup to come through? Does this weaken the leading edge due to it being located off to the side of the center of the plane? I've come across this problem before on other models. I would like to see some pictures of models with hard tanks within them if someone has them. Most of my models fly with bladders but I would surely like to try the metal tanks. Ken
