Micro Electric Helicopter

MIA MEE-KRO 280

Electric RC Micro Heli


The MEE-KRO 280 (pronounced "me-krawh" in Spanish, meaning micro) is one of five models I designed around standard DC motors such as the Speed 280 and small Mabuchi N20 motors. This in conjunction with inexpensive construction materials and easy assembly techniques makes the Mee-Kro heli possible. This is a continuation of my ongoing passion for flying model electric helicopters. Micro Equipment consists of: Ceto FM 4-channel radio receiver. Futaba FM Conquest FP-T5NLH radio transmitter with Rev. Mixing capability. Two Kolibri Pro's ESC with BEC to control each rotor motor independently. Hobbico all-purpose piezo gyroscope for tail rotor stabilization Two Hitec HS-50 micro servos fro pitch and roll control. 7-8 cell 250 milli-amp/hour rechargeable battery pack for +/- 5 minute flight time for intermediate to expert flying. 12 Volt DC 4 amp/hour power source with trainer cord for novice flying. Construction Materials:All off-the-shelf hobby components such as balsa, thin plywood, piano wire, aluminum and brass tubing. Mechanical Components: Ball bearings and gears available via various sources. For additional info check out my web page Mario
