Links zu anderen verwandten Seiten einfügen...) <> = Converting a Jamara Compa X4 Receiver for PPM Output = == Location of the PPM signal == The PPM signal in this receiver is located under the chrystal. The PWM outputs are located on the bottom of the PCB and there is no space to run a wire from one side of the PCB to the other within the case. == Converting while retaining all 4 normal PWM outputs == In view of the above, I decided to go for a KISS solution: solder a 3-4cm long servo extension cable to the 5V, GND and PPM outputs on the PCB all of which are located on the same side as the Xtal. I then ran the extension out the back of the receivers under the Xtal and taped the connector to the side of the RX next to the normal 4 PWM outputs. This way it is very clear what the PPM output is for up to 8 channels (depending on your TX, and the receiver can also continue to be used in normal PWM mode for 4 channels. == Other modifications == One problem with the long RX antenna's is that these do not go well with the spinning props. So I took a 30cm plastic tube, wound the RX aerail around that in a spiral stepping 3-5mm per turn, and then put yellow heatshrink around it. /!\ ToDo: hier gibt es noch etwas zu tun (will post pictures later) <
