Just purchased a Model IV (N149BT)

Thank you, There is a POH, but no harm in ordering a new one. The Pilot’s Guide sounds useful also...

The Pilot's guide will have the max gross weight information...I think. I sold my Kitfox a few years ago and all the paper work went with it.

Your serial number is 1499. Numbers 1400 through 1722 are 1050 max gross weight. 1200 max gross weight serial numbers start at 1723.

Thanks, Tom. That explains why the POH with it says 1050. The A&E that has been involved with it insists it is 1320, which is not even consistent with the 1200 of the Classic IV - Guess I will need to check the logs and see if some modifications were made and if not - just assume 1050. I appreciate the answer.

Aerodynamically the 1050 has a smaller vertical tail than the 1200. On the 1200 the height of the vertical tail was increased 7 inches and the rudder chord increased 2 inches.

Structurally the following changes were made from 1050 to 1200:

• The wall thickness of the lower fuselage tube between the wing strut mounts was increased
• The wing strut tubes were increased from 7/8" 0.035 wall tube to 1" 0.049 wall tube

Thank you, sir.
