The biggest difference between what is the biggest RC helicopters and what is the smallest is the amount of flight time. Bigger helicopters are usually designed for more aggressive and faster flying, because they offer much better maneuverability.

They are good in tight places and can stay away from trees and other objects that might be too low or too high for them. At the same time, they are so big that they can’t be flown indoors or out of doors, unless you plan on putting it on a stick. Smaller models are typically for indoor and/or outdoor use.


Size really comes down to how many stages and pounds of weight you will be carrying. The heaviest of the models (the “heaviest” ones) can weigh over 5 pounds and be held very tightly in your hands. That will depend on what kind of battery and controller system you choose to buy.

Many of the expensive models will have separate controls for each stage, allowing you to easily switch from a hover mode (the slowest speed) to an accelerated mode. They can also be inverted quickly and easily.

Engine Size

There are a few other things that will influence your choice when you are asking yourself, “What is the biggest RC helicopter?” Obviously, the engine size.

If you are new to remote controlled helicopters, and don’t have much experience flying, you may want to start out with a smaller engine, and practice with that. You can always upgrade later, once you know what you are doing.


Size and Price of RC Helicopters

Of course, if money is not an issue, then you want one that is the most powerful. There are literally hundreds of different makes and models of RC helicopters available today.

While some are for extreme pilots only, there are actually mini helicopters that are very suitable for children and for the novice flyer. Even beginners can get a feel for the hobby by purchasing a used model.

Newer versions are also available now that have larger prop models. These come in models that are usually capable of speeds in excess of twenty miles per hour. These are excellent for racing or using in a field trial with another pilot.

Some of the bigger, more expensive models are available with full sized landing gear. This is essential if you are going to attempt indoor or flight, as the gear needs to be able to support the larger vehicle when landing.

Size and Control of RC Helicopters

The size of the helicopter matters a lot. If you are planning on building it yourself from scratch, you need to make sure that it fits your skill level. Most of the popular RC helicopters are relatively simple to fly.

The controls work in a similar way to helicopters that are owned by the general public. It is important to consider whether or not the radio control model will be suitable for your child. Often, smaller helicopters require much better hand-eye coordination than their larger counterparts.
