Avoid these 5 Mistakes for a better Flight Experience
Our hobby is supremely fun and rewarding, but it can also be dangerous and cause damage. Here's a list of 5 mistakes you should avoid to make your flying successful and most of all safe. This is not an exhaustive list, so please hit the reply button below and tell us what your mistakes to avoid are.
1. Flying Into The Sun
I'm sure it has happened to most of us at one point or another. You fly right into the sun and lose sight of your plane. It can temporarily blind you and by the time your eyes adjust back you can't find your model and it has crashed. Even with good sunglasses on, it is still hard to see a plane flying in the path of the sun. Just don't do it!
2. Flying Over the Pits
This is certainly a faux pas at any club field. There should be an established flight line that the aircraft do not cross where other pilots and spectators can safely watch from. If you have a control failure or mechanical issue and the plane veers off over that line (it happens more often than you'd think), then do your best to get the plane away from people and property. You should sacrifice the plane before endangering others. We call it "putting it in."
3. Flying Against the Pattern
If you are the only one flying then the sky is your oyster. As more and more planes fill the air like at events, then a flight pattern should be established. Usually this would be a circle pattern with the close pass to the flight stations going upwind and the far side of the circle would be heading downwind. Never fly against the pattern (flying downwind down the runway) as this has a high potential of causing a mid air collision.
4. Flying at the Crowd
This actually applies to real airplanes at airshows and is a good rule of thumb for us r/c guys too. You should never fly a plane towards a crowd of people. Your turns should be made going away so you can avoid doing this. If you are flying at a crowd and lose the radio signal or something happens (anything can happen) the plane has a high chance of hitting someone. That would ruin your day.
5. Hand Catching Your Quad
There are lots of videos of people doing this, but it is a very dangerous activity. You're putting your flesh and your face in close proximity to spinning props. Those props are very sharp and have enough power to sever a finger or worse. Please find a better way to land that doesn't put you at risk. If you look at the risk vs reward ratio it's a no brainer. The risk is insanely high for zero reward in doing it. Stay safe out there folks.
