Well today’s the big day I finally have all the parts ready to do get the used Losi XXX-S I bought on EBAY up and running.


[Some of these tasks seem pretty easy while others, while not very difficult, I worry I may be missing something or inadvertently screwing something up]

I would appreciate any information on gotchas or things a new person most likely will over look when first setting up a car.

I have to

1. install a pinion on a stock motor.
I am assuming I can kind of eyeball where pinion should be positioned on motor shaft.

2. install a stock motor (P2K pro)
I guess the spur gear should mesh with pinion at center of pinion and they should mesh fairly tight. Is there a way of determining just how tight? Should I put a drop of oil on pinion? The pinion I ordered is made of metal the spur gear looks like it is made of plastic, is that a problem?

3. install a ESC (duratrax intellispeed 16 t)

4. solder 2 capacitors to the motor.



5. connect ESC to battery pack and motor

This is the one that’s got me worried
I believe the ESC will come with a plug which will fit the plug on the battery.
I will need to solder the wires on the ESC to the positive and negative poles of the motor. I have seen diagrams which show you having to make a T and run a wire to the positive terminal of the battery also.

6. program ESC
I guess most of this now auto-program

7. plug esc and servo into receiver
socket 1= servo, socket 2=throttle(esc), socket 3 battery power(esc)

8. adjust transmitter…. just follow instructions in manual

9. install body posts through holes in body, clips to hold on. Antenna through body.


I read in one place that I could run the foam tires on both ocite carpet track and on asphalt. I intend to test car and practice on a parking lot which seems fairly smooth. While the only nearby race course is entirely ocite carpet. I was worried that the asphalt was real abrasive and would chew up a foam tire.
