The Kitfox Series 7 is one of the most flexible and versatile aircraft for factory supported engine packages. Basically if it is 150hp or less it has probably been on the front of a Kitfox. Engine choices are entirely up to the builder/owner and is one of items that makes the experimental amateur built rules so dynamic and exciting.
Kitfox is always keeping an eye on future developments and how they may apply to the Kitfox. There are current builders opting to install Corvairs, BushKing, VW, etc…
Performance: Cruise, Climb and Stall speeds are all variable and will depend on propeller choice, propeller pitch settings and weight. The lightest install and most popular being the Rotax 912ULS. Averages: stall in the low 40’s, climbs of 1000± fpm and cruise of 120± mph. We have seen stalls in the 30’s and cruise speeds in the 150’s TAS at 15000 MSL, climbs at over 1500 fpm and have been up in the flight levels at FL250.
Kitfox Aircraft currently has firewall forward packages for a great variety of popular engine choices.
