    • Must have for Temp/Voltage telemetry for TRX4 crawlers
I am using this in my TRX4 G-500 crawler. I think the temperature is very useful for heavy duty trailing or rock crawling, especially using 3s batteries. The voltage telemetry is an absolute necessity when you are using LiPo; especially when using the rig in such a way that the low-voltage feature of the Traxxas ESC may not be immediately obvious. The temperature probe installation is very easy - simply zip tie the flatter sensor part of the black hooped wire directly to the motor (any motor, Traxxas or otherwise). The readings are quick to transmit and seem accurate thus far. The wire length is just about perfect for the TRX4 chassis, with enough slack to route as desired, but not so much that you have to be creative zip tying the excess wire. The voltage installation will take some basic knowledge in electronics. Traxxas saw fit to fit the voltage wire with a JR male plug with a single wire to be attached to the positive power source. Using the Traxxas battery adapter is not possible without modification of the TRX4 ESC battery connector (which I am unwilling to do on a new rig). Many folks simply solder the red wire to the positive terminal of the ESC connector, and this is fine. However I prefer a plug/unplug option that doesn't require modification or soldering of the TRX4's connection. Because the xl-5 hv ESC comes with a full-voltage takeoff that runs straight to the battery (as confirmed by multimeter measurements using 3 different batteries), I decided to use that as my source for telemetry. However, the takeoff uses a JST male connector. So I simply built a JST female to JR female connector by soldering 2 red 20AWG wires attached to the respective terminals. I completely removed the black wire and the terminals originally attached to the stock connectors. I made the length long enough to feed under the battery tray, but not be too slack. Before attaching to the telemetry connector, I ensured perfect continuity from the red ESC battery connector to the final plug. Out of curiosity I plugged the telemetry unit and checked its continuity, and found that a 9.05Ohm resistor is wired into the unit. That same resistance was present without anything plugged into the telemetry cable... which explains how it works in the receiver box. The later model TRX4s (including the G-500) have BEC voltage going to the receiver. As a result, the telemetry picks up on this steady voltage and reports it to the transmitter *even when the voltage telemetry wire is not connected to the battery*. I would *not* trust this for good battery voltage reporting as it will mask the actual voltage coming from the battery. When I plugged the battery to the telemetry terminal, I could tell I was obtaining real-time voltage -- prior to connection, there was no momentary drop of voltage when I quickly throttled up the motor; post connection, the telemetry showed the momentary voltage dip one would expect from a quick throttle up. Getting the telemetry unit to fit in the receiver box was a bit tedious, but not hard really. I do wish there was perhaps 2-4mm of red wire to make it a little easier. So, save the money on the half-useless Traxxas adapter, buy some bulk connectors with cables and solder your own JR female - JST female adapter. $3 for the temperature mount is silly in my opinion since I connected mine with a zip tie for effectively less than 10 cents. ... show more

    • Not in original packaging.
Item was as described, except it was not in the original traxxas packaging. Came with a free RPM sensor I do not currently have a use for. Lost one star for package, otherwise exactly as described.

    • Did not work.
I bought this to hook up to my traxxas link. So I can get battery voltage and temperature by motor. Follow the instructions that all to work to wire it. And it doesn't nothing. Also you have to buy harness for the motor temperature witemperature wire. This is on a trx4. It works on my Max temperature gauge and potage read out. ... show more

    • Good product
Works how I expected, traxxas makes the new connection for the new plugs. “Power taps”. They just started producing them this month. If all you care about is temp like me you can run both wires in the receiver.

    • If you have telemetry its worth buying.
Works as expected. I didn't buy the gen 1 adapter I just soldered the volt wire (red) to the positive side of the plug from the esc that plugs in to the battery and works just fine

    • Works great
Once you get this part you will have to get the installation parts to go with it. That’s the only thing I didn’t know but it works great for me.
