Quickie Q2 Lite Construction Manual - page 12

.....

The composite structure of your Q2 provides some important 

advantages over conventional metal, wood, or fabric construction. It 

has been tested to loads far in excess of those required for FAA 

certification. Fatigue margins are higher. Contour is maintained 

under load, the structure does not "oil can," buckle, or distort. It 

provides excellent insulation and damps noise. It has no hidden 

joints, no water traps, and is far less susceptible to corrosion.

It is easier to inspect, more redundant and easier to repair. It is 

not susceptible to thermal stress due to temperature changes. 

Properly protected from UV, it has an unlimited life.

Perspective

.....

The builder of an amateur-built aircraft is the manufacturer; he 

is responsible for quality control on all parts, all construction, 

and the conduct of his flight tests. While Quickie Aircraft 

Corporation is not the manufacturer of your aircraft, we do, through 

these plans and services, provide you with information about how our 

Q2 was built and what we feel is the best way for you to build a 

safe, reliable airplane. We do encourage you. to build the airplane 

as shown on the plans because we have found that our airplane 

provides us with reliability and safety, and any problems that we 

experience with our aircraft are documented and reported in "The 

Quickie Newsletter". We have gone to a considerable effort in 

developing the design, the structure, and the systems, and proving 

their adequacy with appropriate tests.

.....

If you modify the airplane and then ask us if your modification 

will work, we cannot give you an answer without conducting the 

appropriate tests and totally qualifying the modification. This would 

obviously be quite expensive. Our concern then, is that if your 

modification is not successful, and causes an incident or accident, 

this would be attributed to our design, the Q2. Because of this, we 

must insist that if you modify the airplane with any major change 

such as an aerodynamic change, primary structural change, or using a 

non-approved engine installation, that you call your airplane a 

different name, rather than a Q2. If you make a major change, you 

must consider yourself involved in basic aircraft design and 

development, an extremely risky business. As such it is not fair for 

us to be associated with any results of your development. We state 

this, not to discourage inventiveness and progress, but to release 

any connection of your new development efforts with our proven 

design, the Q2.

.....

We are particularly concerned about individuals using alternate 

engines to power their Q2's. The Q2 was designed around the engine; 

any change would require an exhaustive test program to determine not 

only the new engine's suitability as an aircraft power plant, but 

also its suitability as a Q2 power plant.

.....

These Q2 Construction Plans have been specifically designed to 

educate you in the construction materials, their use, and to guide 

you through each step of assembly in the most efficient manner 

possible. It is our intent to drastically reduce the non-completion 

rate* common to homebuilt aircraft. With that in mind, we have:
