Pitch response is basically the result of elevator authority. Elevator authority is limited by a number of things, but after the airplane is built, the only one we can affect it CG location. The elevator will be most efficient with the CG closer to the rear of it''s range. Move the CG forward and the efficiency goes away. Move it too far forward and the elevator gets sluggish. Farther forward still and it''s close to worthless and the airplane is closer to it''s expiration date.
Lot''s of beginners and even some experienced modelers think they''re making their models safer by moving the CG an extra bit forward. They are not. They''re simply taking away the elevator''s ability to make pitch changes.
You''re seeing just that.
It has a 64" wing with 685 inches and weighs 9 lbs 9 oz for about 33 oz of loading and is powered by a HB .61. I''''m not very familiar with heavier wing loaded planes and my question, do heavier wing loaded designs typically require a lot of elevator to rotate or does it mean that the balance point should be questioned? It flies good other than hard to rotate and keep the nose up on flare.
One can appreciate that I don''''t want to enter the tail heavy world messing with this thing.
The weight sounds reasonable for a 60 size model. Higher weight only means the CG has more effect for what you''re talking about. And amplifies the CG location effects even more the slower the airspeed.
Not much you can do to lighten most completed models significantly. Lots of ways to move the CG back. Before you do it however, it''s sensible to know more about the airplane, so check it''s measurements out on geistware.com. That''ll tell you a lot about what''s really going on with the model.
