those testors planes were great they were the competitors for COX planes I think they sold for about 15.99 at K-Mart if you wanted a control line plane to mess with you can get a better quality one from BRODAK mfg. they took over the Carl Goldberg line of .049 kits as well as a few ARF and kit control line planes.
www.towerhobbies.com is also a source of control line planes and equipment as well as your local hobby shop, ebay has some offerings and there can be some good deals if you want to depends on what you are looking for
