Is one of them Will Hobbys ? I've heard that Rich Model is just a branch of Will Hobby. If it is, I bought an"40" size Polecat (ARF) from them last fall. It seemed to be well built. The covering was in extremely good shape. Most everything went together, without any major problems. Had to put some glue here & there, normal for today's ARFs. The instructions were basically unusable. The only gripe I have about the plane is the canopy is cheezy. It flies well.
