HAY CARAMBA! This is a tough one and requires a bit of history. The quick answer would be: The F1 QB is a stand-alone kit, and does not require the builder to purchase anything from other airplane manufacturers to complete the airplane assembly. An answer with a bit more history would be more like: Let’s go way back…. Ray Stits built a small homebuilt known as a Playboy. Dick Van Grunsven, of Van’s Aircraft, built one and then improved it. Eventually this design developed into the RV-3. The RV-3 grew into an RV-4. John Harmon built souped up versions of both the RV-3 and RV-4 –these hot rods were known as Rockets. Due to customer demands, John developed a conversion kit (more about that later) to modify an RV-4 into the HR2. Using knowledge gained during the assembly of at least 8 HR2 kits, including Bruce Bohannon’s Exxon Flyin’ Tiger, Mark Frederick then developed the F-1 Quickbuild kit to satisfy his customer demands. The F1 QB is a stand-alone kit, and does not require the build
