RE: Need New Plane for OS 120 AX
biker:
He did say he wanted a scale airplane.
Ron:
Even narrowed down as you have, your choice covers a lot of ground. Scale, kit or ARF, not warbird and not too fast, for $200 to $600 is not my area of interest. Maybe someone with experience in that area can offer suggestions. In the meantime, I would suggest looking through the latest issue of the RC magazines and doing some creative searches such as "120 size RC" on Google.
A word of caution, though. A WWI biplane is a lot more challenging to fly than a Taylorcraft.
Good luck,
Jim
