FK Lightplanes FK9 Mk IV becomes our 21st SLSA since April 15 (a rate of 3 per month!). A longtime ultralight enthusiast with a list of FAA ratings, importer Tony Anderson has moved fast since securing distribution of Germany’s FK Lightplanes. Since my SPLOG two days ago, Tony was able to confirm by copy of his Airworthiness Certificate the SLSA approval for the FK9 Mk IV on November 17th. Here is a proven microlight design built very lightly (590 pounds empty) using fiberglass over steel construction. Powered by a Rotax 912 or 912S, FK9 cruises at 105 knots and climbs 1,500 fpm at gross (with 100 hp engine at 1,146 pounds gross weight). In service for many years in Germany, FK9 is quite popular with flight schools. It also has the slickest of wing folding mechanisms. A single person can unhook the wing — from the tip — and fold the wing.
