service letter is intended to provide you with information regarding the
operating center of gravity range for your aircraft.
have completed a series of flight tests on our factory Model IV-1200
Kitfox™, and our findings support the expanding of the allowable CG
new aft CG limit for Model IV-1050 and Model IV-1200 Kitfox's and Model
IV-1200 Speedsters is 16" aft of the leading edge of the wing.
The old limit was established at 14.78", but that has been
found to be too conservative. At
16", you will find that loading your Kitfox™ within the CG range
to be much easier.
make the appropriate changes in your builders manual and/or flight
manual referring to this Service Letter.
We are also aware that many of the Model IV-1200 Builder's Manuals were shipped with weight and balance data sheets that incorrectly stated the aircraft gross weight as 1050 pounds, and that some builder's had problems getting their aircraft registered at the correct gross weight of 1200 pounds. We have re-written the section and can send a corrected version on request. Contact Customer Service at 208-454-1443
