FLY THE ROLLING CIRCLE
A favorite among pilots, very difficult to fly well, rolling circles are one of the hardest stunts ever. The rolling circle is the only one maneuver that’s feared more than any other moves in the full-scale competition aerobatic world.
To explain further, rolling circles are a combination of a turn and a roll—a better term might be a “rolling turn.” There are different types of rollers, named according to the number of rolls in the turn, the number of degrees in the turn, and the direction of roll. However, there are so many factors required to do them well such as maintaining altitude with collective timing, applying constant roll rate, applying elevator whenever knife edge, and many more.
Basically, the rolling circle withstands a steady rate of turn, a steady rate of roll and a steady altitude.
One of the most challenging and admired maneuvers in all of aerobatics is the rolling circle. As a rule, you can achieve early success learning most maneuvers as long as you first understand the proper control inputs, and hand-eye coordination adds the final touches to perform the maneuver nearly perfectly. The rolling circle, however, is even more challenging in that it depends almost entirely on hand-eye coordination from the start. This article covers the steps to flying a rolling circle, but you’ll execute the actual maneuver by reacting to your plane.
Let’s begin by noting that using rudder in a rolling...Continue Reading
The antenna position in (photo 1) has the antenna pointing straight up at the model which can result in signal drop outs as the antenna's tip is the weakest point.The best antenna position is to bend the antenna upward at 90˚(Photo 2) This guaranties you will be in the strongest part of the antenna radiation pattern unless you are directly overhead. The signal comes off the side of the antenna.
The radiation pattern is shaped like a big fat airplane tire with the antenna being the axle. The signal off the end of the antenna is inherently weak.
But above 30MHz is the horizontal polarization (bend antenna 90° to the side)
