Figure 2 – The bottom of the RC servo circuit board with the K shunt resistor installed. The author makes no guarantees regarding the success or suitability of this modification for any particular application or purpose.

RC Buggy steering servo Comments: Use insulation on the resistor wire and keep it down close to the board. Losi Strike steering Comments: There’s a good chance it’s a poorly made fake. A great tool to have is a test circuit that generates the servo pulses.

That problem can be solved by decreasing the pulse stretcher gain by a similar factor. RC model servos are fairly sophisticated devices that incorporate both position and speed feedback with a goal to provide precise position control. There are limits to what can be done to a RC servo without a major circuit redesign.

This article will describe in detail how you can modify a commonly available servo Futaba S such that good variable speed control will not only be possible, but very practical. Tests indicate that the BA contains the servo control circuits with the BAL as a separate H-bridge motor drive circuit. With your servo connected to the servo driver or pulse function generator, you should be able to operate the servo from complete stop to full speed in either direction smoothly and easilty over the You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.


Please see the Datasheet below for detailed dimension information.

Futaba S3003 – Servo Standard

The difference in pulse width the error signal is then “amplified” with a pulse stretcher. Since this increases the total servo loop gain by the same factor, the servo will tend to become unstable.

This resistor increases the speed sensor feedback by a factor of about four, which provides full-range speed control. Making the physical and electrical modifications described in this article to a RC servo will void its manufacturer’s warranty. Alot of used 30 size heli on Ebay come with this servo so when you get your catasheet, put those away and go with better servos, in the end you will be spending more in servos but way less in repairs. The round silver button to the right of the K resistor is the bottom of the motor.

Futaba Standard Analog Servos

There are no product questions yet. Being that it’s a basic servo it’s not too bad for general applications. The reader takes full responsibility for the success or failure of the servo to perform as indicated or described. If you intend to do both hacks to a servo, do only the mechanical modifications mentioned in the above article, then continue below.

Make you connections quickly minimizing the board and component heating. Figure 1 – D3003 inside of the S RC servo and the speed control modifications. A fix to this problem is to increase the scale factor gain of the speed control feedback so that the maximum motor speed range corresponds to the full 1 mS range mS of the input signal.

International orders may be charged import duty dependant on local import laws and duty rates. General instructions for doing this are covered in the continuous rotation hack.

Also use the copies in on-road without any issues but not as reliable as the original. Use solder wick to remove unwanted solder if you accidentally create a bridge. UK Deliveries If you live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3. This resistor causes am increase in the speed control feedback.
