I absolutely loved reading through the evolution of this rig and to hear how you learned new things as you went along. Keep it up!

AX10 Scorpion RTR turned NMRCC Trail Class Build
- Thread starter Chingon
- Start date
I had another competition on March 23rd, and as I posted in my 1.9 Trail Class thread, it was a good turnout. No changes to the truck other than putting it back on the old Moab tires since the Ruptures are illegal in the class now. I want to pick a set of the 5.25" Tusks, but they have been back ordered for a while.
The truck did really well and the courses seemed to suit me pretty well. I ended up with 3rd place and got to set one of the courses (Course 3) for the first time, which also ended up being the hardest of the day and only half of the competitors were able to finish it. The first course I only had 1 reverse against me, but I wasted a lot of time recovering from a roll without a penalty and had to skip the last bonus that I could of made because I didn't have time for it. The second course I only had two reverses against me and I decided to skip the last bonus because I wasn't sure if I could make it and it had the potential to seriously ruin my run. Screwing around afterwards, I was able to get it on my 4th attempt, so a good call to skip it probably during my run. The final course I set, you were doing pretty good if you could just finish it without pointing or timing out. I tagged a few gates and skipped a bonus, but I was able to get a finish.

Enjoyed reading about the build thread. I have 2 of these AX10s and in between other projects, I have been working on one and seeing how it goes.
Thanks! They are a little long in the tooth, but still a relevant platform performance-wise.
Not much of an update, but I decided to finally switch from the BS-6 receiver I have been running over to an FS2A receiver. The FS2A is a lot more compact than the BS-6 and a bit lighter. I went ahead and bought four of them unsoldered to switch everything I have over to them. Buying them unsoldered is cheaper and allows you to solder on the pins in whichever orientation suits you best. I used a couple of old servo plugs to space the pins appropriately from the board. Notice the button facing up in the picture. It is used for binding so you don't have to screw around with a binding plug. Super easy to bind to the GT5 receiver.
Side by side comparison with the BS-6:
The FS2A weighs 2g each versus 8g each for the BS-6:
I printed up a little bracket and mounted it under my axle plate with a single M3 screw for the lowest place to put the weight possible.
I also took the opportunity to delete the power switch from my Rhino 40A ESC. You just need to connect the white wire to the red wire. The cleanest way to do it is to bridge the two at the board with solder, but I didn't want to cut off the heat shrink since I didn't have any to replace it with. Instead, I cut the wires just long enough to give me room to work with them, soldered them together, then covered it with some heat shrink. You can also see where I cut a relief in the axle plate to route the wires from the new FS2A above the axle plate.
I also decided to cut out a section of the heat shrink over the actual heat sink on the 40A Rhino ESC and drill some holes in the 3D-printed parts sandwiching it in an effort to try to keep it cooler.
