LITTLE TIPS ABOUT BUILDING YOUR OWN RC HELICOPTER

Flying RC helicopter is really very exhilarating. Their versatility gives a RC pilot a complete access to the three-dimensional space in such a way that no other machines can! I have played RC helicopter for more than one year but still find that I have just learnt a few tricks that it can perform.

There are generally two micro-helicopters ( indoor ) in the RC market. I have already planned to buy one of them as they can fly inside the living room and even take off on ours hand. Unlike those operated by gas, these electric helicopters are very clean and give out no terrible noise at all. In one nightfall, I visited a web site, which is about how to make a hand made RC helicopter. I was totally impressed and started designing my own helicopter. Here is my helicopter:

Several weeks after completing the first model as I describe above, I start to turn my view on a flybarless collective pitch rotor head. The reason for this modification is very simple. Just to get more stability especially during descending. The tail rotor parts from a Concept EP can be converted into a collective pitch rotor head for my helicopter. However, The tail rotor hub is a little bit heavy and big in size. Therefore, I decided to made one from fiberglass circuit board. Just click the photo for the flybarless collective pitch modification I.

This first attempt was actually not success due to the lack of tester damper. Worse was to come, the swasplate came apart during a flight test as the rotor disk is too unstable. I overlook its importance to the cyclic respond at the very beginning and it was doom to failure. Here is my second attempt: (click the photo below for details)
