metal gyro RC helicopter


I spent the last two days, some new metal gyro RC helicopter Robinson R66 helicopters, turbine. Although still in the experimental category, FAA certification is expected in the next 30 days as Robinson and FAA work in detail.
Complete after a few thousand hours of light Bell Helicopter turbine 206 for ease of comparison. Last year, Bell announced it would stop production of five instead of Bell 206B Jet Ranger, referring to the R66 as a base. The design intent of founder Frank Robinson is not only difficult, but also economically. R66, the company's first turbine helicopter illustrates this very well, and after the flight, I think Bella made the right choice.
R66 is powered by a Rolls-Royce RR300 (250-C300/A1 model number), the new engine is proof motor series 250 (the same engine used in the 206B). Bridge of 37 degrees, which is easily accessible for maintenance. The engine produces 300 hp to 270 hp From time to time by five minutes and choked 224 hp Maximum continuous. The principle is simple: the power switch (a nice feature that allows you to start the engine, you can go without candles is no longer necessary to connect the computer) for authorization and press the start button (which is closed, you need to do login), and 15 percent of the team and traction control and speed of light fuel N1. In the 65 - to 67 percent of the starter is disengaged and N1, the generator is activated.
R66 Softfloat choice, and that he feels "a little bigger and a" little "heavy piston engine R44 is. Flew with Doug Tompkins, chief pilot for Robinson, who did his best, R66 experience of flight tests. We sailed by a couple of 64 per cent, and we are approaching 60 knots takeoff Doug proposal is based on 100 percent of face value. began to draw on the collective VSI fall 90 per cent to 2,000 feet per minute and 100 percent, because we were the Banshee. This should not take a long time to feel comfortable with the helicopter and ran rotation. planned and mostly a lot of fun. "With more than 180 degrees, 90 degrees, and also the influence of self- rotation soil full of love. R44 is just easier.
Another feature is comfort, the cabin is eight inches wider than the R44. Cyclic flight control reserves Robinson shaped arrangement of T. This will not only facilitate the transition from R44 to R66, but the T-bar is very comfortable during the flight.

In the buy Brushless Motor is probably good. Frank Robinson found again and filled the need. R66 and flexible operation of the piston turbine engine, since the height of the flight. It is also widely accepted in the world of aviation gasoline is difficult to obtain or simply not available. And operators and contracts that require turbine R66 approach.

There is much more to say about this RC helicopter brushless motor, stay tuned for the full story in an upcoming issue of AOPA Pilot.
