Navion
I have the RCM plans. Junk! The forward 1/3 of the wing is practically solid balsa block!! Find AN old Berkeley models Navion on Ebay. I think the RCM plans catalog list a guy that has new plastics for thier plans Navion, that just happens to fit the Berkeley. A friend did one a few years ago, and man was it beautiful. It was fast too, but light and able to slow down. It really turned heads!! Expect a lot of crunched wood in those old kits. Its like they were die crunched during an earthquake. And expect to replace some wood and do a little modifying. The kits were capable of FREE Flight. So , there is a little work to getting one right. The inboard wing section is semi symmetrical, and the outboard sections are under cambered. Wow. But it did fly great!!!
