BEGINNERS

Question: Is it true that Model Helicopters are hard to fly and will break my account before I learn it?

Answer: NO! This is not true at all. Model Helicopters are more difficult to fly than Model Airplanes, but as long as you wish to learn it you will. Let's put this way, if you thing I'd like to fly model Helicopters you probably won't but if want to fly them you probably will. A 30 size Helicopter might cost more than twice of a trainer airplane but it is not build out of balsa. With proper help you will be able to reduce your crashed to a minimum.


Question: What is the best Helicopter for a beginner ?

Answer: In my opinion, the best Beginner Helicopter is the Kyosho Nexus S. It's easy to build, setup, mantain and replacement parts are very cheap. Also it flyies good out of the box. It should be built with a O.S. 32 SX-H engine for great power and reliability. All radio equipment should be Futaba or JR, although, I prefer Futaba. The Futaba 8UHPS is the best radio when it comes to cost/benefit in the market, but the Futaba T6XH will also do the job as well.

Helicopter Flying

Many modellers agree that a model Helicopters is the most interesting and challenging type of model available. It can do everything that the full-size can do and can even fly manoeuvers that would be impossible or too dangerous to do in a real one, like loops, rolls and inverted flight.
Almost anyone can learn to fly a model Helicopter, though it does take more time and practice than learning to fly a fixed wing model and a good instructor is very useful.

How that Radio works ?!?

Rotor Speed and Pitch YAW Control
Pitch Axis Roll Axis


Function of the Gyroscopic Stabilizer (GYRO)

When the main rotor is being driven at steady speed, the tail rotor prevents the fuselage of the helicopter from turning in the opposite direction. If the torque is changed to change the speed of the rotor, this balance will be upset and the fuselage will start to turn.

The gyro has a flywheel and sensors that can sense and swinging body movement and send a signal to the tail rotor pitch servo to chance the pitch.






The signal from the gyro causes the tail rotor pitch control servo to change the pitch in the way that will stop the fuselage from turning (yawing). Note, however, that only stops the rotation, but does not return the fuselage to its former heading.





From Ground Up!

Here I'll try to teach you, your first steps into flying a model Helicopter. The lessons will go from the very beginning (How to Hover) to the the 3D flying (I hope I can get thru that). More lessons will be added gradually as I get time to write them.

Choose a Lesson:

1st Lesson - Tips on building your Heli.
2nd Lesson - Preparation for First Flight.
3rd Lesson - Beginning to Hover.
4th Lesson - Flying Around.
