Building the CH 750
The CH 750 kit includes many great features and is much easier and quicker to build. The kit includes many CNC pre-cut and pre-drilled skins and components, and also includes CAD Drawings and Photo Assembly Manuals. The modern CH 750 kit has been developed to provide the builder with everything needed to complete the airframe – with only basic tools and skills. The CH 750 airframe requires less than 400 hours to build from the complete factory-supplied kit.

The above video is of the new CH 701 rear fuselage kit. Note that all the CH 750 fuselages are matched-holed and as easy to assembly as the new 701.
The above video is of the new CH 701 forward fuselage kit. Note that all the CH 750 fuselages are matched-holed and as easy to assembly as the new 701.
Approval from the FAA
On May 11-12, 2010, the Federal Aviation Administration’s (FAA) National Kit Evaluation Team (NKET) performed an onsite evaluation of the CH 750 kit to determine that the CH 750 kit, as produced by Zenith, meets the intent of the “51% rule” and to allow an amateur-builder to register the plane as an “amateur-built – Experimental” aircraft (meeting the “major portion” requirement of Title 14, Code of Federal Regulations part 21, Certification Procedures for Products and Parts, 21.191(g).
The FAA made its official determination that the STOL CH 750 kit will “allow an amateur builder to meet the major portion requirement” and that the STOL CH 750 kit will be added to the official “Revised Listing of Amateur-Built Aircraft Kits. Importantly, builders can use the FAA checklist to help them determine exactly how much commercial / professional builder assistance may be used without violating the “major portion” requirement.
The STOL CH 750 and Cruzer are some of the few kits on the market that doesn’t just come with assembly instructions. The kits includes detailed blueprints of every part of the airframe, as well as a detailed assembly manual. In fact, the CH 750 can be ‘scratch-built’ from the Drawings and Manuals, although this requires additional skills, time and tools.
Drawings and Manuals
Supplied with the complete STOL CH 750 and Cruzer kits, the drawings are not just assembly instructions (as with most kits), but are detailed 11″ x 17″ CAD blueprints of the entire airframe assembly and individual parts, and come with an assembly manual. The CH 750 Drawings & Manuals package includes a CD-ROM with high-resolution Photo Assembly Guides for the step-by-step assembly of the STOL CH 750 kit.
Supplied with a serial number, you can actually build your own aircraft from “scratch” following the Drawings and Manuals. Scratch-builders can purchase any individual parts or components directly from Zenith Aircraft Company. If purchased separately, the cost of the drawings and manuals is deductible off the cost of the full kit.
Zenith Aircraft Company’s workshops are popular with sport aviation enthusiasts, giving them the opportunity to gain valuable hands-on experience in building their own kit airplane. Participants get to actually start assembling kit parts under the direction and guidance of factory professionals, and “graduate” from the workshop upon completing construction of their own aircraft rudder tail section for one of Zenith Aircraft Company’s popular kit aircraft designs, including the high-wing Zenith CH 750 series or the sleek low-wing Zenith CH 650 cruiser.
