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 […]
The new Parkzone Albatros D.Va BNF is a great little flyer and our contributor Michael York is really impressed with it. Take a look at the video to see just how cool this plane really is. Be sure to watch it all the way to the end and check out the complete review in Model […]
