Note: The design of the Yamaha 3 Cylinder and the SkyTrax Gearbox pushes the prop flange of this combination in the Kitfox 4 about 1-7/8" farther forward than the Apex / Skytrax combination.

All of our motor mounts have been 3D CAD designed and guaranteed to work with our Header and our secondary Oil Cooling / Thermostat Kit. ALL tubing material is 4130 Chromoly Steel, LASER Cut & Notched, and Professionally TIG Welded. The design has been G Load Tested to 1.5x (6 G’s) - See Video at top of this page!

Kitfox 5-7 Sidewinder / Nytro Motor Mount: This 3 Cylinder Yamaha motor mount is constructed just like our Apex mounts and to the same standards. It locates the prop flange in the same exact location as the Apex. We have designed this motor mount to have very desirable CG with no need to add aft ballast. The cowl is currently the biggest challenge in this installation. There are a few options, but starting with the Lycoming Cowl & Firewall will be the easiest.

Note - 1: This video is after several cycles, returning to 1G (0 Deflection), and repeating. Motor Mount always returned to 0 Deflection, within a few thousands of an inch!

Note - 2: This was a “Pre Production” mount with Main Tubes being 1” x .047” and all other tubes .5” x .035”. To add an additional factor of safety ALL production Main Tubes have been increased to 1.125” x .058”, and all other tubes increased to .625” x .035. In addition the Engine Mounting Tabs were increased from .070” to .100” and more recently increased to .125”.
