Wow.....I learned to fly on one of these also.....in 1975. K&B35, with a Cirrus radio. Mine still had the option of a rubber-banded rear stab, I remember just gluing it though, and it worked fine. Orange and yellow were the colors...and what an ugly plane....I did love it though. I actually had that one until 1985. I was moving into a new apartment then, and left it on the porch and someone stole it. It didnt have any of the equipment left in it though. It was a nostalgic piece of my RC history though. It will work fine for you though. Just follow what these guys are saying with CG on the spar and it will fly like a bird. Have fun, and thanks for sharing....wow....nice to hear of someone that is using classic to learn on!
