Launch Report #20

I built an 18mm monocopter and flew it twice on A8-3s....
It needs more of a B or C.
The first flight, the motor flew through the motor mount and flew 20 feet across the lawn. On the second, the motor stayed in but it didn't get above 3 feet. Sigh.
Oh, and a warning: with a fresh 6V lantern battery, an Estes continuity light bulb passes enough current to fire and Estes igniter. Adding a 100-ohm resistor in series with the bulb should make it safe.
