Larry, With your "past experience kit and scratch building control line airplanes" you may feel ready for a 1/4 scale Cub build, however I think maybe another airplane "step" or even two between the Nextstar and a 1/4 scale Cub might be a good idea in the flying experience area. A slightly smaller and simpler kit built taildragger would allow you to gain taildragger flying knowledge and also allow you to "warm up" your past building skills for the Cub project. This approach might help you turn out a better 1/4 scale Cub and save it from damage during the learning curve of landing and taking off taildraggers. Once in the air, flying is the same, but they are a different bird on the ground. Not sure what kit to suggest, maybe a Sig Kadet Sr. built as a taildragger, or even one of the slightly smaller J-3 Cub kits like the 40 size Great planes Cub or the Goldberg Anniversary J-3 Cub (both 76" wing span and should fit in your 72" truck cover at an angle). This would give you a good step up in plane size, taildragger time, and balsa building warm up. I also fly a 1/4 J-3 Cub and as for me, piloting skill wise, there were many steps between my trainer and my 1/4 scale Cub. Just a thought.........run it around in your head.
