Can anyone tell me why the Vne on the CB-1 is 10 mph slower than the Classic? It appears that the airplanes share the same wings and longeron mods to give a bit rounder fuselage on the Classic. Jut purchased a ground looped CB-1 but it has the spring compressors on the gear. Also looking for a left landing gear. If at all feasible, I'd like t convert it to a Classic.
