So, you just got that shiny new "__insert_brand_here__ 6CH 3D FUN" heli?
You think you will crash it? Maybe you are trying to keep it in one piece? Keep reading. Otherwise, go have fun and keep 911 on speed dial.
This is not a toy
That warning on a box is there for a reason. If your box does not have that warning, start looking at another box.
Unless, of course, you are looking for a coaxial helicopter. A little less in the fun department, but a good place to start.
RC helis are exciting and addictive, and only recently became available to the masses at an affordable price, so the misconceptions, presumptions and false opinions are more plentiful than ever. You think you know how deep in this you are? We'll see about that.
I would have to say that the #1 reason new model helicopter pilots crash is lack of knowledge! The first thing anyone that has been flying model helicopters for a while will tell a beginner is get a simulator, practice on the simulator and study. Although the new gyros available today make model helicopters considerably easier to fly than previous generations, you still need a general understanding of it's control system, and you have to fly the helicopter 100% of the time!
Before you attempt to fly, do homework. RCGroups and the rest of the internet are full of knowledge, you should learn how to set your heli up even if it says RTF. You have to know what EVERY wire and pushrod is for and what it does, otherwise your chances of a successful landing are not huge.
The problem beginners face is, you cannot stop and think while flying!
Once you lift the helicopter off the ground, the helicopter is naturally unstable and requires the pilot to keep telling it where ( not ) to go all the time. It's like juggling on a unicycle, except you can only fall once, then you need to repair it and it will cost you. Eventually your thumbs will learn what to do, it's just a matter of whether you will learn it the hard way or not.
Naturally, a helicopter will not try to stay where you left it. It's not designed to. Also, there is no mechanical or electronic device keeping it in the air, so your thumbs will need to take care of this. Helicopters are pretty quick too, a wrong move and it's gone. Helicopters are non symmetrical either, the main blades spin in one direction, so a helicopter uses a tail rotor to control that imbalance, that creates another imbalance, but this the responsibility of the pilot to correct it.
The hard part of taking off with a tail rotor helicopter is spooling the helicopter up and just as it begins to lift, you must input a little right aileron to hold the helicopter in place and add power. This is a delicate operation not enough aileron and the helicopter drifts left. To much and you flip over and bust a blade or worse. This is an acquired skill not that hard, but will take a little practice before your doing picture perfect liftoffs!
Why 4 Chanel coaxial helicopters make good 1st helicopters.
Coaxial helicopters have 2 motors and 2 sets of blades that spin in opposite directions. They cancel out the torque of each other and we don't need a fan at the back to stop it from spinning.
No fan on the back equals no blowing sideways!
In order to turn the helicopter we slow down one motor just a bit and the torque of the other motor turns the helicopter. Coaxial helicopters also tend not to wander and will correct themselves if you just let the stick centre. New pilots get a chance to think move the stick and learn how to move the helicopter around without the helicopter constantly wanting to take off in a different direction every 2 seconds. The drawback of coaxial helis is they lack agility and, therefore, are very hard to fly outdoors, especially in wind that would be no match for a CP heli.
