I'm going to clear up a common misconception here. Electric is not cheaper. It also doesn't require less knowledge. Given any airframe bigger than a .25 size, if you compare the cost of a motor, speed controller, 3 batteries (don't even consider buying fewer than that), a wattmeter (can make one for about $6 though) and an adequate charger and power supply you'll be invested significantly more than on an engine, fuel tank, starter and battery, glow driver, and a couple jugs of fuel. Not to mention that if you put the wrong prop on a glow engine it will lug and not pull the plane very well, whereas you put the wrong prop on an electric things overheat and go poof. Plenty of people go electric exclusively these days, so decide what your ultimate goal is and start with that kind of power system so you don't have to rebuy all of your support equipment.

Now comparing a .40 size glow powered trainer to the Hobby Zone Super Cub, sure the Super Cub is cheaper. It's a much smaller plane and far less capable. As you've seen already, it can't handle any significant wind and is not maneuverable enough to do much beyond fly in circles. So if you want to use the components from the Super Cub to outfit another one go ahead, but understand that you'll be very limited on the days you can safely fly.

And one last thing. Don't plan to crash. That's the number one mistake of beginners (for other posters, please note how that word is spelled). You crashed your Super Cub because you flew in wind that the plane couldn't handle and let an inexperienced pilot at the sticks. In short, you did the hobby the wrong way. But if you do the hobby the right way (appropriate plane in appropriate flying weather with a knowledgeable instructor) crashes are actually quite rare. And with balsa models total loss crashes are even rarer still. I had a bonehead moment two weeks ago and nipped a tree with my trainer (was getting ready to instruct and had a group of student watching- Doh!). It cost me about $1 to fix the broken nose in about 2 hours time. The planes that crash well generally don't fly well, so plan to fly and avail yourself of the proper instruction so as to avoid crashing.
