Model helicopters come in all shapes and sizes, including some that actually fly. There are different skill levels required to complete construction, and if you are building radio-controlled model helicopters, then you’ll also need to learn how to fly them. No matter which kind of model you choose, models are fun to build and are a terrific hobby for enthusiasts both young and old.
Choose a design based on your skill level. There are many model helicopters that are easy to build even as a beginner. They often feature parts which have been pre-assembled, so you simply need to install them into the chassis of the helicopter.
Construct the interior of the helicopter prior to placing it within the chassis. Beginning models will require little to no interior construction, and most of the guts of a helicopter are taken up by the engine, anyway. However, some kits will require you to build the model from scratch.
Ensure that the blades and the gyroscopic weights on the rotors are balanced. Balancing the weights will prevent the helicopter from being unstable during flight. Test the blades at lower speeds to see if there is a wobble to the blades and the helicopter while in motion.
Connect your blades and gyros to the motor. This is the most important step, and also the one where the most significant errors can occur. Tighten the blades as much as you comfortably can to ensure they don't fly off during flight.
Replace the stock parts in your helicopter with upgraded aluminum or composite parts. Upgrades often lighten the weight of the helicopter, making it more aerodynamic. They are more expensive than stock parts, but will often increase the value and longevity of your model.
