When building an RC Airplane from a kit (typically an ARF) you are going to get a complete set of instructions that will take you through the whole process. But these manuals vary and there are lots of tips and techniques that you pick up over time. It comes with experience. Here are a few tips that will be helpful to you. And you will discover other neat little tips and tricks as you go along. If you have built other kinds of projects the experience will come in handy.
The best thing you can do when beginning in this hobby is to join a club with other RC airplane hobbyists. Their experience will prove invaluable.
It may sound silly but make sure you install the propellor correctly and make sure you really tighten it down! As tight as you can get it without cracking it! This is especially important if you are using a plastic propellor.
Bracing the control rod
You can improvise and add balsa wood for different purposes. In this picture you can see that I built a balsa wood brace for the Throttle control rod. That rod is particularly long and it tended to bow which affected control. This wood brace is just a few pieces of balsa wood glued into place. It holds the control rod reasonably straight yet allows it to freely move back and forth.
Some of your control rods may have wooden extensions. This achieves the same result. For example, the control rods to my rudder and flaps are half wooden.
On off switch
Typically you mount an on off switch on the side of the airplane. But they also make a neat little switch that has a charging port on it. for a dollar more. This allows you to charge up the batteries without having to take the plane apart or remove the batteries. It's a convenient little option.
