    JR DMSS rpm telemetry

    I don't think that you can just plug the RCEXL RPM plug into the hub. As far as I know, each type of JR telemetry sensors has an electronic board with an a specific interface and an ID so that the Tx knows where the signal is coming from and how to interpret it.

    Your Opinion-This is not a "Which radio is best" thread!!!

    I have had all 9 channels (and up) JR radios. None of these radios gave me any problems. (Apart from the use of 53Mhz overseas that made me lose 2 pattern planes, several years apart, and both late afternoon. We (modellers) were officially sharing this frequency with radio amateurs and they were...

    Throttle and choke servos

    Being my first gasser and not realising that these motors vibrate so much, I initially set up the servo travel with no play. I should have given these setups some play at full throttle and no choke positions. That is why the servos motors burnt out. By using powerful servos with metal gear we...

    Throttle and choke servos

    Thanks for the idea TazmanianDevil. I had given up on this thread. This is worth a try. I have been thinking about a small bicycle cable and sleeve with as little play as possible inside the sleeve. One end attached to the servo arm and servo tray and the other to the throttle arm and the...

    Throttle and choke servos

    That make sense. I have tried as well the same thing and did not notice any difference between 80/85 and 100% throttle. How about a miniature bicycle cable and housing that is attached on one end to the servo and servo mount and on the other end to the carburetor and engine mount. The...

    Throttle and choke servos

    I took apart the first servo that failed and found that 1 winding out of 3 is burnt open. The second one has exactly the same symptoms, so it must be the motor again. After some homework, I have come to the conclusion that one must give quite a bit of play at high throttle and at no...

    Throttle and choke servos

    I have had 2 x 110oz HV MG servos fail after about 100 flights on an Extra 91". They are used on the throttle and choke, so about 5 to 6 inches behind the firewall and are linked to the engine with a 2-56 metal rod and nylon clevices. They were not "singing' in the min or max positions and the...
