Four Wings Helicopter Project

An inexpensive helper RC: 11 paces

Airborne R/C helicopter is really very exciting. I' ve been playing R/C choppers for over a year, but I still think I just learned a few moves that he can do. In contrast to gas-powered electrical choppers, these are very neat and do not make any horrible noises.

One night I was visiting a website that deals with the production of a handmade RC helicopter. So I was really amazed and began to develop my own helicopter. This is my helicopter: You' d be surprised at the materials I use to make the helicopter's primary structure.

There is a 3 * 6 bearings (5.4 mm x 6.8 mm) on both ends of the pipe and a 5.4 mm x 6.8 mm black synthetic pipe. Naturally, the end of the pipe is first increased in size to accommodate the bearings fixed. So far, the helicopter's base configuration has been finalized.

Next stage is the installation of the gearbox and engine. A total of 4 boreholes are bored on the base unit (2 boreholes at each end). Gluing all sticks first with super glues and then with epi-oxide glues. I select the same materials for the rotary heads as for the principal bodies - the printed circuits.

First, I have to say that the wheel must be robust enough to resist any vibrations, otherwise it could be very hazardous. The cyclical inclination of the sword is solely determined by the inclination of the flying -bar and the cyclical inclination of the sword is only determined by the inclination of the flying -bar.

This is actually a 3mm neck that can be inserted into the mainshaft. Previous units make rotors move in one sense. Rotator turns at very high speeds. Now, it is really a very easy construction as the rear wheel is driven by a seperate engine.

As a result, there is no need to build a complex transmission system from the engine to the rear. Fasten the rear arm to the trunk with 2 bolts and some resin: Rear rotors consist of an engine, the rear leaves, the rear wave support pipe and a knife support.

Rear regulation is controlled by altering the rear drive revs. Disadvantage of this kind of steering system is slow behaviour at fix inclination of rotors. Inside an RC helicopter the cockpit works together with the rearervo. With this version, however, the governor must cooperate with the ESC (Electronic Velocity Controller).

In the beginning I try this with an usual top (the big one for the Gashelicopter). Really poor results are that the speed of the rear wheel changes from period to period even though the helicopter is on the desk. Later I buy a microphone that has been especially developed for small electrohelopters and to my amazement it works great.

All the things that make up the rear section are shown in the picture. Each of the two balsamic knives is held in place by a wooden support, which allows a firm spur inclination. Just glue the engine to the rear arm with a simple layer of resin and attach the rear axle support pipe to the engine in the same way.

Rear leaf is made of Balsaholz. Protected with tubing to minimize rubbing between shovel and fan. Tilt and mass of both wings must be exactly the same. My draft is to install the rudder servos between the engine and the switch bracket pipe.

Thus, the pipe has used the robust synthetic housing of the servos as one of its support media. These arrangements give additional rigidity to the master slide holder pipe as one side of the servos is bonded to the engine while the other side is bonded to the pipe.

On the other hand, the portability of the servos and the engine is compromised. To make the entire construction more stable, an extra column is added to the master switch holder pipe. It weighs only 3.8 g (extremely light), which makes it ideal for helicopters indoors.

Although the tuner has only four canals, it can be switched to a five-channel RX. It' s just temporary the easiest top I can find in the whole wide openorld. In contrast to the GWS top I used in my GWS helicopter, it is very sturdy and the centre is very precise.

When you are planning to buy a mic top, it would certainly be a good option for you! In the above picture the DC 5V engine, DC 4.5-0. 6 and DC 1.3-0. 02 (from right to left). In my first try the micro4.6-0. 6 is used.

This engine will burn out quickly (or I should say that the engine's plastics are melting) because the rear wheel's performance requirement is much greater than I thought. Currently the engine on my helicopter is still in very good working order and is running on five volts.

Today's rear engine is a 16g GWS engine that delivers much more performance. It' s been used before to steer the 300 engine in my helicopter. Since the 300cc engine is now substituted by a CD-ROM drive, the Jeti 050 has been substituted by a Castle Creation Phoenix 10 brushless ESC. 2.

He will be modifed to add an additional input signal for the patchervo. Only 2 serves are required for a fix pitchesesign. Computer-assisted telemetry is required as the rear controls must be combined with the butterfly valve controls. With a Piccolo helicopter, this function is taken over by the Piccoboard.
