Choosing A Good Helicopter


People seem to think because the helicopters are electric and cheap; it will make it easier to learn how to fly. I've trained something on the order of 300 people to hover and fly helicopters over the years and I know for a fact that is the safest, easiest and cheapest way to learn.

Well, that's debatable. For two thing, the inexpensive electric helicopters are difficult to fly in the wind. Yes you can buy a nice two for around $200. The CX is the easiest to learn to fly as compared to the CP and the equivalent, but all helicopters, fuel powered or electric, are difficult to teach yourself to fly. Chances are nice you will break lots of parts in the learning method and most likely give up after spending lots of hours fixing, practicing and/or tons of money in the learning method. dislike to discourage you, but this is the reality of RC helicopters.
Choosing A Good Helicopter

Fuel powered helicopters are difficult to learn to hover and fly, small electric helicopters are even harder and the tiny ones are worse. You will need a large open area to practice hovering and even then, chances are you will break things. This is something you will unfortunately find out after you spent a bit of money on your helicopters and replacement parts.

If you haven't already, tried installing a new and/or different type of glow plug. it is possibly there is a hole in your fuel line inside of your tank where the fuel line is attached to the metal pick up. That would cause it to stall when the tank is half empty. The engine might be overheating due to the lean mixture caused by the possible split fuel line. There are so lots of electric helicopters out there and it depends on what you consider is expensive.

Save your $100 because buying those helicopters would be a total waste of money. As the saying goes, you only get what you pay for. The same goes for the cheapest electric ARF airplanes. You will need a proper trainer airplane, and any RC warplane is well beyond any beginner's abilities.

Learning to fly RC airplanes is something that is possible to learn on your own, but definitely not recommended. If you ever receive a chance to find a club or an experienced flier who will let you fly a proper trainer, then you will see what I'm talking about. I believe collective helicopters are easier to fly than fixed pitched helicopters. You are correct about the CP. The small electric helicopters are for the most part are harder to fly than fuel powered helicopters.

The first recorded depiction of a possible manned helicopter is a diagram drawn by Leonardo da Vinci in the 1400s. The knowledge of physics necessary to successfully build a working model did not yet exist, but they understood the concept of an "air screw" that if turned hasty would be able to drive the machine as well as a pilot in to the air.

There are several different people who are considered to be the inventor of the helicopter. I could write a book explaining it in detail, but I'll cover a couple of the primary contributors to the development of rotary wing aircraft. The ancient Chinese invented a toy for children that you can still see today. It consists of a propeller as well as a shaft through the middle of it. If you spin it quickly in your hands or with some other force such as a rubber band you could make it lift up and hover briefly before coming back to the ground.

Over the work of the next few centuries lots of other people toyed with the idea of a helicopter, but again the amount of power necessary to drive such a machine in to the air was not possible to generate. The invention of the internal combustion engine made the power requirement a reality. The next hurdle that needed to be overcome was the concept of torque - the phenomenon that causes the body of the helicopter to spin in the opposite direction of the main rotor.

Paul Cornu invented a working piloted helicopter in 1907, but it was not a successful design. It only generated lift for about 7 seconds. Another Frenchman, Etienne Oehmichen built and flew a working helicopter for about 1 kilometer in 1924.

There are lots of other men who contributed to the development of rotary wing aviation - lots of to list here, but a thorough search of the library and/or the web can give you tons of insight in to the development and design of all different types of helicopters.

As early as 1910, Russian born Igor Sikorsky began working on development of a manned helicopter. By 1940, his working design had become the model for all modern helicopters. It consisted of a main rotor as well as a tail rotor that is used to counteract the torque generated by the main rotor. This design is still used in a vast majority of helicopters today, which is why Sikorsky is considered the father of the modern helicopter.
