This is the Great Planes EP Yak 55M 50 Sport Scale Aerobatic ARF Airplane. Winner of several world aerobatic championships, the Yak-55 underwent several design changes in 1989 — most notably a shorter, more tapered wing - which resulted in the Yak-55M. ElectriFly and Great Planes has captured the unique look of the Yak-55M in a 50" wingspan model that flies like a much larger plane.
