I AM NOT SELLING A KIT, only a new, full-size copy of the classic old time RED ZEPHYR 72" span free flight or RC PLAN for you to build one for yourself.

The RED ZEPHYR is a vintage design that was so very popular in the 1930s & 40s. It was really big, as were all old time free flight designs for Brown ignition engines and later Super Cyclones and Ohlsson & Rice 60s. I thought you would enjoy this old newspaper advertisement as well as the Scientific Models catalog listing.  

This design can easily be converted to 3-channel RC. It has ample dihedral which means in a tight turn it should roll out level when the controls are neutralized. 

This is one really big, long PLAN for you to build your own RED ZEPHYR.
