Micro space shuttle chuck-glider conversion

This tiny 12-inch-long foam chuck glider (link) seemed perfect for conversion to RC using micro components.

My first idea was to use the "brick" ESC/RX/servo unit from one of the Horizon micro planes. So I cut off the top from the Shuttle with a hot-wire, dug out some room, then transfered the "brick" and motor/gearbox from a Hobbyzone Champ to the Shuttle...adding Depron elevons onto the rear of the shuttle for control (see first photo below). Unfortunately, when I test-flew this configuration, the Shuttle could only manage a controlled descending glide to the ground. Apparently the Shuttle needs more speed to fly than the rather low-pitch-speed power setup of the Champ provides.

But I'm not one to give up after a single try. For my second try, I ordered one of those tiny new micro-size Spektrum-compatible receivers from HobbyKing (it weighs only 2-grams), and some tiny 1.7-gram servos to go with it. Then I stripped another micro plane in my hangar of it's high-RPM 5-gram brushless outrunner motor and 7-amp ESC. For a battery, I chose the smallest 2S LiPo that I have -- a 200 mAh one.

This new configuration surprised me with the dramatic difference in flight properties. Now the Shuttle climbs strongly at full power (almost too strongly in seems as though a thrust angle adjustment may be in order). The Shuttle even cruises along happily at only half power. The only real problem on the remaiden was the touchy roll rate, because I still had on the big "paddles" for elevons that I had sized for the slower original configuration, and excessive throws to boot.

Nice Job!

They did this conversion in one of the magazines a year or two ago, and I have been looking to do the conversion ever since. Yours turned out beautifully
