- The lower (lighter) the wing loading the better: lower stall speeds and better knife edge capability. The ability to fly away from a botched maneuver is important.

- The higher the power to weight ratio the better: blast out of trouble or jump out of a hover.

- The more the control surfaces move the better: faster maneuvering.

- The larger the control surfaces the better: more control of the air.

- The more powerful the servos the better: to prevent flutter.

- Digital servos: precise motion throughout the range and tighter centers.

- The faster the servos the better: faster corrections.

- The larger the fuselage side area the better: better yaw control.

- The larger the size the plane the better: less sensitive.

- A computer radio: mix out quirks, switch rates easily using one condition switch.

- The correct amount of right thrust: the plane must go up straight in a hover.

- Lots of money: buy the best, stretch the envelope, have a backup.

- Nerves of steel: the lower the better.

- Bulletproof airframe: don't have a mechanical failure, especially servo linkages.

- Bulletproof engine/motor : hovering on the deck has an unhappy ending if the engine/motor quits.

- Rearward CG: flies inverted virtually hands off for better manoeuvrability.

- Extensive preflight: you can't afford a mechanical failure in the air which should have been caught on the ground.

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)

To make a good doppler pass you need a few things, here are some pointers on how to make good doppler passes.

1) First you want to keep the background noises as low as possible. Flying with a loud gas engine in the background, or adding music to a soundtrack, or talking close to the recording camera can make it difficult to extract the audio needed for doppler.

2) You must fly at a constant throttle setting. For doppler to work, the "source" frequency must remain constant. This means your rpm must be constant during the doppler pass. If you rpm drops (due to voltage sag or moving the throttle stick) then your "source" frequency changes as well and you will not get a valid doppler reading.

3) You MUST fly in each direction at least 5 to 8 times the distance from the microphone to the plane. If your plane passes 100 feet from the microphone, then you must fly at least 500-800 feet towards the microphone and 500-800 feet past the microphone. So the closer you are the better. I shoot for 50 feet and I often place an MP3 player in the flying field, set it to record audio, then fly over it as low as I can. This way you are not flying too close to your camera man. If you do not fly the required distance ratios, then you do not get a complete doppler shift, and you will rob yourself of speed.

4) Fly in a straight line coming to and going from the microphone. Do not pull up or turn. Always fly in a straight line.

5) Do not gun the throttle, you need...Continue Reading
