I am using an OS FS 91 w/pump in the front. I think that the reason it is so tail heavy is because I used the OS Aluminum engine mount which does not place the engine out in front far enough. I also used 4-40 rods all around and a Sullivan tailwheel, which adds weight to the rear.

I am really upset about having to add any weight at all to the plane. Plus, I won't be able to use my Tru-Turn spinner because now I will have a Harry Higley Ultra Heavy Hub on the nose.
