I flew mine for the first time yesterday. Mine was extremely tail heavy at the 30 percent or 4.98" CG location. I was lucky to get it back on the ground. I had to land it hot in order to keep it from tip stalling, and just breathing on the elevator made it snap. Do not believe the elevator throws on the instructions. I landed so hot that I knocked off the landing gear. I mounted the servos as instructed, three in the tail. I installed the tank over the c.g and the receiver and battery are in the nose at the firewall. I have a YS 140L on it for power. With this set up and with a not so light motor, I still have to add 1 pound 12 oz of weight to balance at 4.5 inches. I am extremely disappointed with this weight. I am going to move the rudder servo up and use a pull, pull. This will help, but I do not think it will help to the extent I would like. Does anyone know how this bird can come in at 10 1/2 pounds the low end of the advertised weight?
