The two-place version of Van’s Aircraft’s popular RV-3 homebuilt, in 1/3 scale.
The RV-4 STORY is ready o be told, but before I explain this giant-scale project, I’d like to list the standards it was based on. Above everything else, I wanted a pretty exact-scale rendition of the RV-4. the model also had to be aerobatic, simple to assemble and fly, transportable in a compact car, and use a Quadra engine along with any standard R/C system.
