This great micro flybarless 3D machine is ready to fly out of the box, which is good because the box is also the carrying case. We got one of the first releases of this helicopter and our contributor Aaron Strietzel gives you his thoughts on this little 3D machine. Be sure to check it out in [...]

When YouTube’s Womackke saw a giant bird’s nest at a local park, he decided to fly his quadcopter with GoPro video up to check it out. He notes, “To my surprise the bird flew at me. The bird was not hurt and I didnt do this again after seeing their response. This tree is so [...]
This gorgeous scale Blackhawk MH-60K Night Stalker is a custom build from Hajimefactory.com. It’s based on an Align T-Rex 500 chassis and a scale four-blade rotor head. Check out the video of this beauty in flight — it looks exactly like the real deal!
While winding resistance (Rm) is an important consideration in calculating losses, an equally important factor is motor efficiency. Real world efficiencies for electric motors – as measured on a dynamometer – can be all over the map. Some high-quality brushless motors can hit efficiencies in the 90% range, while others may be under 60%. This [...]
Innov8tive designs have always carried top quality Scorpion and Cobra motors and ESCs, but recently they started adding some top-quality multi-rotors from Next Level. Here at Model Airplane News we are always looking for a new way to bring information to our readers and when we got the chance to review this good size quad [...]
How It All Works – This now results in two opposing forces acting on the tail rotor system. The aerodynamic force wants to streamline the blades to zero pitch while the centrifugal force wants to rotate the blades to their maximum pitch. These tail rotor weights produce a centrifugal restoring moment (CRM) because they act [...]
After an idea came up late 2008 a small group of Multiplex funs came together in Hungary for a small contest. Rules were simple and clear: same planes (Easy Star, Easy Glider) were allowed to compete in two simple events: time gliding and gate race. The uniformity of the planes assured the contestants having the [...]
