RE: Vintage Cox Airplanes .049
Many years ago, I used to fly the two CL models you have noted. One of which was flown many-many times on a parking lot in Phoenix. They all seemed to have some variant of the Baby Bee for power. And thus cheap fuel and a marginal battery could be used.
One of our readers is well into older CL models (most here are in to modern R/C types), and straightens folks out on occasion too. He wants to add into his collection an old aluminum based model that I got new and have used on occasion for decades now.
We have a few readers who live near to you now too.
