Designed by an R/C modeller named LaMar Steen in 1970, the full-scale Skybolt became the most successful a 2-place homebuilt fully aerobatic biplane in the world. Over 450 Skybolts have been built and flown in the US, and another 200 or so in 29 other countries. It is larger and easier to handle than smaller biplanes, yet is capable of unlimited aerobatics. The Skybolt is a straightforward, honest, and absolutely beautiful biplane.
