I was looking for the cub before I bought my colt. I dont know why they discontinued most of the models they built. I never new they made a military cub. I've looked everywhere for some of there older models but I cant find them anywhere. Ya I know what u mean by being heavy. I have an os 70 surpass in mine and it took alot of wieght in the tail to get it to balance. But it still does fly good.
