Easy to spot, the fake has a white dafasheet, the real thing is black. A great tool to have is a test circuit that generates the servo pulses. There are no product questions yet.

Futaba S3003 – Servo Standard

Components Needed for Hack 1 ea – 5K miniature multi-turn trim pot. If you fuatba to do both hacks to a servo, do only the mechanical modifications mentioned in the above article, then continue below. There’s a good chance it’s a poorly made fake. International orders may be charged import duty dependant on local import laws and duty rates. I chose to use a trimpot.

The main cause of this problem is that while the futtaba speed control feedback level is adequate for normal position servo stabilization, it is insufficient to match the 1 mS mS input datashheet width variation when the servo is used as a drive motor. Don’t forget to remove the limit-stop bump on the output gear per the other hack if you haven’t already done so. Henk January 28, In other words, perform this procedure at your own risk.

Futaba S3003 – Standard Servo

Conclusion I hope you find this modification useful for your purposes. Alot of used 30 size heli on Ebay come with this servo so when you get your heli, put those futava and go with better servos, in the end you will be spending more in servos but way less in repairs.

Also an Internet search using “RC servo” will produce an abundance of interesting and sometimes useful links. Figure 3 – View of the insides of the RC servo showing the new trimpot gray and capacitor yellow.

There is some shift of the zero-speed pulse width with this s300 and the trim pot. General instructions for doing this are covered in the continuous rotation hack. If you spend over If you are skilled at surface mount techniques, just replace the K resistor just to the left of K, “” daasheet a KK surface mount resistor. Also use the copies in on-road without any issues but not as reliable as the original.

The servo now drives the motor forward or reverse when it see pulse widths less or greater than 1. Tests indicate that the BA contains the servo control circuits with the BAL as a separate H-bridge motor drive circuit.

Earlier RC servo designs combined these functions within a single dxtasheet i.

Email to a Friend. Making the physical and electrical modifications described in this article to a RC servo will void its manufacturer’s warranty. Being that it’s a basic servo it’s not too bad for general applications. Figure 3 shows the 0. The difference in pulse width gutaba error signal is then “amplified” with a pulse stretcher.

This capacitor decreases the gain of the error circuit by a factor of about four in order to balance the effect of the previous mod and maintain servo stability.

If you think you’re getting a great bargain, you’re probably not. They can be purchased from Tower Hobbies among others. Unfortunately, the hacked servo circuit has a very narrow input control range and is difficult to impossible to speed control accurately, though it has adequate speed and torque.

The author makes no guarantees regarding the success or suitability of this modification for any particular application or purpose. If you google “Fake Futaba S Servos” you will find more information. Just Me February 27, Be the first to review this product. It is very similar in design, weight and operation to the Futaba S Servo and can be used as a direct lower cost alternative.

The result is a well-behaved speed-controlled servo drive with full-range speed control, good torque, and stable operation. If you spend between 40 and 48 – The modified servo has excellent full range control datasheey very good low speed torque.
