This info might be of interest to you guys.
From Dec 1988 Kitfox Owner Newsletter, pg 2.
From Jan 1990 Kitfox Owner Newsletter, pg 3.Some of our builders with the Model 2 have had problems with the FBK-5 aft aileron bell crank. The bushing was not properly located on some of them delivered over the last 4 months. If yours will not fit and pivot freely, send it back and we will send you another. If you have access to TIG or oxyacetylene welding equipment, you can grind away the excess material at the corner of the FBK-5 and re-weld it.
RIGGING DETAIL: on page CF-18 of your builders manual, step 69, it tells you to have the tops of the FBK-9 Individual Flaperon Bellcranks approximately parallel to the Mixer Bellcrank. Actually, on the Model 2 the inward ends of the FBK-9's when properly rigged will point down, possibly 15* degrees or more, with the flaperons leveled according to instructions.
MIXED UP BELLCRANK: About 25 FBK-7 Mixer Bellcranks were inadvertently built incorrectly, as a mirror image. Most of these incorrect bellcranks were shipped in November 1989. Please check to see if your Mixer Bellcrank looks like the one in diagram F-5 page F-6 of the builders manual. lf your bellcrank is not correct, please let us know and
return it for the correct bellcrank.
