The trend today seems to be toward big lithium batteries and powerful, brushless outrunner motors. Without question, this is a positive development, but these airplanes tend to be on the large and heavy side for pure indoor flying.

New submicro equipment, coupled with a small lithium battery, is the answer if you're looking to construct smaller, lighter aircraft with good agility.

This little fella is fast, rolls madly, and has lots of power, while remaining stable and controllable. Since it's lightweight, the front end doesn't shatter into jigsaw pieces when the aircraft makes unplanned contact with something.

The carbon fiber spar caps are inlet into the top and bottom of the wings. The motor is held on the carbon fiber tube fuselage spine by two bushings cut from Tygon tubing. The bushings are positioned on the mount, then the motor is pushed onto the bushings, leaving a small gap to allow the motor to move backwards in the event of a collision.

The landing gear is bound to the carbon fiber tube fuselage spine with kevlar tow saturated with foam-safe cyano.
