The final assembly has us installing the top deck, bumper, battery holders and the electronics.
Ok, on to the build!
Build Notes:
The TRF419XR allows several different options at this point; different center braces, weights, battery holders, etc. These spare parts are in a separate bag, so don’t forget to pull them out to see the options.

One thing to note – the stock spur gear that comes with the TRF419XR is not suitable for stock class racing. Top top it off, the spur gear mounting setup is a little odd as well, meaning not just any spur gear will work. I found that the Panaracer-Xenon spur gears work the best.
Since your electronics will probably not match what I have, I left the install of these out of the build. It’s pretty straightforward, however, so you shouldn’t have a problem installing yours.
Step 1:
The first step is to assemble the servo horn and attach it to the servo. You can use the included servo saver setup or, like I did, attach a standard horn. I’m not to keen on the Tamiya servo savers – they seem to flex a bit too much for me.

Step 4:
Attach the mount to the chassis. You’ll notice it’s only attached on one side – this is an example of a floating servo mount. This helps retain the correct tweak on both sides of the car. Don’t forget to pop the drag link onto the servo horn.

Step 5:
Here is where you’ll have some options; I went with the carbon brace as a starting point. I also attached the weight in the center, however I chose to do it after I had already built the car. (See the end of the manual for chassis rigidity options).

Step 6:
Attach the motor. I will be running in the 17.5T class but, since my motor hadn’t arrived at the time of the build, I dropped a R1 Wurks 10.5T in for show.

Step 10:
Attach the battery pad. It’s a bit long so I cut it down a little to fit.

Step 11:
Slip a wheel spacer onto the axle followed by the serrated nut. The spacers can be left off to help tune the width of your TRF419XR.
