Just built a pair of the Li'l Hacker 2, with electric motor systems. It's a foam wing Half-A plane that comes with two sets of parts in one kit. (See photo) Strapping tape was added along the trailing edge of the wing for strength. Full-length wing spars were substituted for the shorter ones in the kit. Instead of covering, two coats of white glue (thinned with water) were applied to all surfaces. A curved-wire landing gear was installed to enable launching without assistance. The ESC is a generic one from Ebay. The Ztron timer is very small, light, and easy to use: it has adjustable pots for speed and time, with a push button to start the motor.
Electric components Installed are:
Motor: 2212, 1400KV
Prop: 7"-5p
ESC: 30A
Timer: Ztron CL Simple Timer
Battery: 3S LiPo, 850 mA Hr
Plan to try it out as soon as a nice day comes around.
