The 87 Extra SHP, developed by Scott Stoops, will open your eyes to how well a 50CC aerobatic aircraft can fly. Light, precise, willing, and powerful, the Extra delivers precision and freestyle 3D performance like few aircraft in its size class.
Weve given the 87 Extra all of the good stuff: 4-40 ball link hardware, pre-finished canopy and hatch, pre-finished motor box with aluminum bracing, carbon one-piece landing gear with aluminum-braced mount, pre-hinged wings and stabs, carbon wing and stab tubes, carbon wing and stab receiver tubes, carbon tailwheel, aluminum-hub wheels, genuine ultracote, wing bags, and stab bag.
The 87 Extra accepts all common 50CC-60CC engines, and includes a canister tunnel and mount for the MTW TD-75K canister.
