In addition to the radio control helicopter circuits published online, you can take a standard servo gearbox, some bearings and mechanical parts very difficult to play without paying the price of size, weight, etc.

When focusing on the radio control helicopter box and prototype,Recommendations for top radio control helicopter performance Articles you need to consider many aspects. Keep in mind that it is appropriate to try to get sturdy materials and will last for surely at some point we'll have to improvise clamps or mechanical parts, which are carefully treated, but then we have serious problems during a flight.

Materials

The materials I used for the box:

-         1mm sheet iron bent and specially arranged with the necessary steps and everything so when I was assembling the space available to me seemed insufficient circuits, thankfully after I found the opposite.

-         In addition to the metal box on the inside put a "tray" of iron too, where you can place the levers, which are plastic and steel.

Below that tray I perfectly position the circuit board to the radio control helicopter voltmeter, and eventually I put a plate extra conditioning the signal to be sent via RS-232.

At the bottom of the box you can see the two packs of rechargeable battery 1350mA / h capacity are two packs in series to provide a voltage of 9.6 V for the transmitter and CMOS circuits, in the case of using any circuit 5V need stable, just add a small circuit with a 7805 which is a 5 V regulator pos, and I recommend the TO-220 package can be mounted as a circuit "in the air" with only the 7805 with support a screw to the cabinet.

Opt for the arrangement that best suits you for the transmitter and encoder module, which can be part of the same plate or not. Because the idea is that you can use different combinations of these two radio control helicopter modules, getting good versatility and scalability, because the same equipment can be upgraded later to put an encoder module with a microcontroller, for example.

Disposition of modules

There is just one more detail of the case and what would be the assembly of the 4 potentiometers for electronic trim (use these because they had no trim mechanical levers). Besides these two elements add a few key investors that can be used both to select a function called Dual Rate or reverse channel. Finally, at the center and above the planned box radio control helicopter antenna connector, you will place a simple PL-239 with a shortened rod correctly VHF frequency.  Do not panic, when trying to connect two computers to each other in the radio settings coach / student, follow the basic steps.
