Depending on the gyro, it can be used as a wind canceler. I hear that people say gyros are cheating, I disagree. Gyros are the future of RC fixed wing aircraft. I remember when helicopters were all but impossible to fly before gyros. Now they are as common as a lipo pack,
Also gyros have had a huge impact on modern aircraft design, for without them lots of them could not even fly. Think of all the incredible and yet to be developed aircraft that are still to come that simply will not fly without a gyro. Think of all the new maneuvers that have never even been seen yet that our kids will be doing all because this, "cheating technology" a gyro.
I watch so many of the old guys struggle to take off with their warbirds not going straight down the runway because they aren't quick enough in the rudder. A simple, cheap gyro on the rudder only would make their flying exspierence so much more fun.
I also see so many people on the fence because a little wind has them so scared, that they won't even take their plane out of the car. Again a gyro, if set up properly would change all of that for them.
As to the cheating, a gyro will not fly a plane for you. If you do not know how to fly a plane, it will crash with a quickness. Gyros are so good now, that you can set them up to be transparent. For example, when you press the stick to full deflection, the gyro is turned off so it does not interfere of the control surface. Then when the stick is at the center, the gyro will become active. You can also control how aggressive the gyro latches on for corrections. The. At the flip of a switch, it can be turned off.
So you have the guy that refuses to, "cheat, sitting on the sidelines because of a little crosswind or the guy flying his plane getting better every day. You see the gyro won't do a rolling harrier for you, it would to a pop top, a harrier, a crankshaft, or knife edge spin. It won't fly your plane inverted, or do a low to the ground top speed, knife edge pass. However it will make you a better pilot and help you progress much faster than someone that's constantly faced with all the little things that make learning to fly an expensive and often frustrating endeavor.
I don't use a gyro, but I recently helped a friend set up a Demon Cortex gyro, and he is in love with the way his plane flys now. In the end, it's a choice we all name on how we look at technology. I for one tend to embrace new tech, especially tech that makes life easier and more fun.
