The following images are of an owner installation of the new Green Sky Adventures HKS-700e Top Mount engine package for Challenger II and Challenger aircraft. Continuing our mounting theme of paying only one drag penalty, the Green Sky top mount on the Challenger utilizes gearbox down configuration, with low carburetors, and forward, above the wing exhaust. Much of the flat plate drag area of the engine and remaining accessories get a free ride. Our HKS package for the Challenger also maintains the identical thrust line and angle as current production models. Basic mounting of the engine involves nearly zero airframe modification. The mount actually bolts up utilizing two existing holes. Your Challenger can easily be returned to Rotax power if ever desired.  Flight report will be available asap.
