Questions & Answers
Yes, this product is effective.
A loop with a small plastic retainer is included, which must be wrapped around the motor housing. You'll need to detach either the motor or the motor wires to install it; I found it easier to detach the motor.
Any voltage that is plugged into the sensor will be recorded. It will record system voltage if you connect it to the receiver. The part 6541 will measure the voltage of the battery. It's even possible to connect it to a separate BEC.
It didn't work for me in this configuration, but it did once I attached and plugged in both (along with Traxxas Part 6541).
Selected User Reviews For Traxxas 6521 Temperature and Voltage Sensor, Long
This is what I use in my TRX4 G- Crawler with 500 points. I believe that the temperature is particularly useful for heavy-duty trailing or rock crawling, particularly when using 3s batteries. When you're working with LiPo batteries, voltage telemetry is a must-have. especially if the rig is used in such a way that the low-pass filter is used. The Traxxas ESC's voltage feature might not be obvious at first. br>br>Installation of the temperature probe is simple - Simply zip tie the black hooped wire's flatter sensor section to the motor (any motor, Traxxas or not). The data is transmitted quickly and appears to be accurate so far. The wire length is just right for the TRX4 chassis, with enough slack to route as desired but not too much that you have to zip tie the excess wire. br>br>The voltage installation will require some basic electronics knowledge. Traxxas decided to use a JR male plug with a single wire to connect to the positive power source for the voltage wire. Without modifying the TRX4 ESC battery connector (which I am unwilling to do on a new rig), using the Traxxas battery adapter is not possible. Many people simply solder the red wire to the positive terminal of the ESC connector, which is fine, but I prefer a plug-and-play solution that doesn't require any soldering or modification of the TRX4's connection. br>br>Due to the fact that the xl-size A full-featured 5-hv ESC is included. I decided to use that as my telemetry source because it has a voltage takeoff that goes straight to the battery (as confirmed by multimeter measurements using three different batteries). The takeoff, on the other hand, is JST male. So I just soldered two red 20AWG wires to the appropriate terminals to make a JST female to JR female connector. The black wire and terminals that came with the stock connectors were completely removed. I made it long enough to fit under the battery tray but not too long. I made sure the red ESC battery connector was connected to the final plug before attaching it to the telemetry connector. br>br>Out of curiosity, I plugged the telemetry unit in and checked its continuity; I discovered a 9. The unit is wired with a 05 ohm resistor. The same resistance was present even when the telemetry cable was not connected. This explains how the receiver box works. TRX4s from later generations (including the G-1) are more powerful. The receiver is powered by a BEC voltage of 500 volts. As a result, the telemetry detects this constant voltage and sends it to the transmitter *even if the voltage telemetry wire is disconnected from the battery*. I wouldn't rely on this for accurate battery voltage reporting because it will obscure the actual voltage from the battery. I knew I was getting real-time data when I plugged the battery into the telemetry terminal. volts in time When I quickly throttled up the motor before connecting it, there was no momentary drop in voltage; The telemetry showed the momentary voltage dip that one would expect from a quick throttle up after the connection. Getting the telemetry unit to fit in the receiver box was a bit of a pain, but it wasn't impossible. I wish there were at least two of them available. To make things a little easier, I used 4mm of red wire. br>br>So, save your money on the half-priced item. Buy some bulk connectors with cables and solder your own JR female - it's a waste of money to buy a Traxxas adapter. JST female adapter is a connector that connects two JST connectors together. I think $3 for a temperature mount is ridiculous, especially since I connected mine with a zip tie for less than 10 cents.
Please note that unless you connect the red connector to something, you will not receive a temperature reading. If you plug it into the receiver, the receiver will give you a voltage reading. The majority of you probably want this to check your battery level. Obviously, Traxxas' design team hasn't caught up with the rest of the hobby world in 2020, so if you want to get a battery voltage reading, you'll have to disassemble your battery connector and attach yet another Traxxas adaptor to it. But don't forget to pick up the $8 zip cord you'll need to connect the sensor to your motor. Seriously, Traxxas, your lack of creativity is almost comical. Better yet, save your money and stay away from telemetry entirely. In any case, it's a waste of time.
I'm a big fan of technology, so when I first got into RC trucks, I bought a Traxxas Hoss 4x4 VXL 1:64 scale Traxxas Hoss 4x4 VXL 1:164 scale Traxxas Hoss 4x4 VXL 1:164 scale Traxxas Hos At their current prices, I would have expected something similar to be installed by now. Furthermore, locating the numerous part numbers required to install this sensor is a hassle. You'll probably need a few more items to make the installation go smoothly (magnet and gear) and worthwhile (since you're tearing down the truck's main components, you might as well put in the RPM and Voltage sensors as well). Worst of all, I still don't have any data from the sensors after connecting the sensor wires to the receiver. My Traxxas Link phone app shows that I'm connected to the receiver and that I'm connected to the truck, but the middle arrows representing data flow between the transmitter and receiver are always red and never turn green for my Hoss 1: br>Let me start by saying that I know what I'm doing and that the installation is not incorrect. I have a Traxxas X-treme that I use for racing. 1 MAXX 8S MAXX 8S MAXX 8S MAXX 8S 6. Traxxas E-Motor REVO 2. 0 6S 1: 8 Arrma Typhon 6S 1 Arrma Typhon 6S 1 Arrma Typhon 6S 1 1: Arrma Kraton EXB 8S 8, Arrma Kraton EXB 8S 8, Arrma Kraton EX There are five more, each of which has been heavily customized, with the majority of the electronic speed controls (ESC) and receivers having been replaced.
Don't be put off by my negative review. I'm confident in the part's functionality because the one I eventually received worked perfectly. I have a Rustler VXL and wanted telemetry, which isn't well explained in Traxxas materials in my opinion, so I'm going over parts to see if I can help. If you're plugging it directly into the receiver, this sensor will be used. I, on the other hand, purchased the telemetry expander in order to obtain full telemetry, which included motor temperature, esc temperature, voltage, and GPS. I realize it's excessive, but this is my toy. In any case, if you're going to use the expander, you'll want to get the 6526 or 6527 sensor, which "auto-calibrates" itself. detect". In essence, if you have the expander, all of the sensors (except RPM) plug into it, and only one plug connects the expander to the receiver. I also wanted the expander because I wanted my speed to be tracked by GPS rather than RPM. In a nutshell, get your hands on the auto-pilot. If you're getting the GPS or the expander, look for sensors.
You'll also need the installation parts once you've received this part. That's the only thing I didn't realize, but it's perfect for me.
I think the design could be better than a temperature probe that you zip tie to the motor, and for the battery voltage, you'll need an adapter, but the adapter they sell is for the old style traxxas plug, so you'll have to cut and tap into other wires.
This is what I'm using on my 1/10 scale monster truck. You will not have enough length if you choose the shorter one. br>For example, a 1/16 scale, the shorter version is better.
