RE: kit built vs arf built
Nitro Pilot... your absolutely right about there being some used treasures, if one is careful and patient and look them over well. Inspect the wings for warps and view the stab sections to appear to the naked eye to be perfect. Several of the planes in my hanger are used and the price of a used plane is often quite attractive.
I've a World Models Cub with a Saito .90 flat twin, all servos and receiver that was purchased for $300, heck the motor alone retails for $699 right now. A Flair Sopwith Pup with Saito .56 and all but the two wing servos was $200 and it flies wonderful. A Goldberg Anniversary Cub with fabric covering with Saito .50 for $200. A Hanger 9 Taylorcraft with Zenoah G23 and all servos and receiver was $250.
The two kit built of those four are the better fliers.
