The B- 29 has just released the X- 1. It’s fun to recreate the flight of the X- 1 to break the sound barrier, with Chuck Yeager at the controls.
The airplane had retracts and a smoke system, and in
addition to carrying aloft and launching the rocket-powered
X- 1, it could drop parachutists. This airplane flew with seven
receivers, 20 servos, and 16 batteries. Now that is some RC
As I’ve gotten older, my airplane projects have become
smaller and lighter. I enjoy building and flying compact,
electric-powered foamie warbirds—no more large gas-powered
airplanes for me.
Thinking about a new design effort, I knew I could do a
four-engine bomber, and to make it more interesting, so
why not try a B-29/X- 1 project such as Mac’s, in a smaller,
I’ve had a lot of fun with profile electric warbirds, all built
around a “standard” hot-wire-cut foam wing core I’ve used for
dozens of fun-fly airplanes. The wing core has a fairly thick,
full, symmetrical airfoil, a slightly tapered planform, and a 48-
inch wingspan. I cut down foam core to suit whatever design
I’m working on at the time.
I laid out a profile B- 29 with a 48-inch wingspan, 40-inch
