Finding the right pieces for your radio control helicopter

Each radio control helicopter needs batteries to function properly. They may need to be replaced after 2 years or so- it depends on how much you care about your rc model. You can find a dragonfly, which is equipped with a four-channel radio with three servos and the receiver does all the electronic functions including the gyro and the regulator. Remember to analyze details so you can ensure top functionality.

The test of maturity has been to connect two servos to servo tester automatic movement for one hour at 6V. and half an hour with live lithium batteries, this test is to ensure that the servo does not have any defect of youth, the complicated mechanisms often fail or the beginning of their life when they have aged too much, it is preferable to burn new servo in the bank to join us in-flight malfunction. During the test the servo has been heated to about 38 ° when we fed 6V. When we used the live battery temperature has reached 46 º bearing in mind that the servo has not stopped moving to one side, can be considered acceptable.

The radio control helicopter servo has high quality details, the metal is great and it covers the entire body except the crown of the first pair that is plastic. This is to reduce the noise of the servo and the wheels are spinning faster, and being also the least effort support this material without problems. The core is housed in a bronze bearing inserted into the top cover and the output shaft carries the usual bearings. The central body is aluminum servo and the sausage is coreless motor that is cooled with high efficiency - A coreless motor is a motor that has no air gaps in the rotor, which responds much faster, but still carries brushes.

The central radio control helicopter box covers fit with two O-rings and the output shaft also carries another with which the servo is sealed except for the screw heads where we do not believe you can reach into any liquid due to pressure tighten.

You do not need to remove it because the engine electronics and potentiometer are glued and this action could destroy the servo is not expensive but costs money. It is of course the radio control helicopter flight test period, but this will first need to mount it on any device and then let the time to make final.
