It’s 9 deg outside and everything is covered in ice and snow. But I found a parking lot that is clear. So at lunch it should be above 10 deg F.
I am going to just make a couple passes and some circles to run my car.
I went over all the set up stuff last night.
Calibrated the ESC to my transmitter
Ran a motor test to get the full throttle sensor position.
I am amazed at seeing 72000 motor rpm on a 2s battery. Now I just want to scuff the tires without flipping over or hitting a pole.

That was fun. Cold, but fun.
I went out to a parking lot and made a couple passes. Just around the lot and set the steering. Then back and forth full throttle passes. Then full throttle with full brakes. Then circles both clockwise and counterclockwise until my fingers went numb.
I did not flip over. I did spin out a couple times.
I did not hit any poles or curbs. But did notice a touch of understeer with power on. That could be the slippery new tires, cold ground or both. Over all it seems very fast but very controlled. I really need a dirt lot. But they are all covered in ice at the minute.

The weather in Iowa has been absolutely terrible for RC cars. So I am just hanging in the shop looking for things to do. I noticed the front tire will spray dirt directly on the ESC and steering servo. To help prevent this I mounted some front mud guards. There are actually the rear “wing” fairings that come with the Proline flow tech body. They only required drilling a single mounting hole. They screw directly into the front of the chassis and should prevent dirt from covering the inside of the chassis.
I have no idea if they are a good idea or not. They can be removed in seconds if they are a problem.

Slight change of plans
I had planned to use a Tekin RX8 gen3 ESC. I have a Mamba x in it now but the weight limit of the Mamba x is a little low. And since I need the Mamba x for my rock crawler I went on line to purchase the RX8. I could not find one without buying a motor . I have a pro4 4500 motor and done want another lower KV motor and can’t find a combo with the motor I want. I did not want to spend 300 plus for a combo that includes a motor I can’t use. On top of that I would need a Hotwire 3.0 for another 60 bucks.
So I decided to buy a Castle Monster x. I can’t see any reason this ESC should not work. I will keep my eyes open for an RX8 but at least for now I’ll use the Mknster X.
Come on spring!!

The monster X is an awesome Speed control. It comes with massive 6.5 mm bullet conectors. Pre tinned three color wire. And it comes with the sensor cable included.
The data logging is fantastic and I have a blue tooth adapter that allow me to program from my phone.
If that was not enough it spun the motor to almost 70,000 RPM! That’s freewheeling the drive train and ballooning the tires. But about 10,000 RPM more than I got with the Mamba X I use in my rock crawler. It is also very smooth. I drove around my shop at a very slow speed. It is super controllable and drifts and brakes really nice. I even saved about a hundred bucks over the Tekin RX8 because I have the Programming cables.

Well that did not go to plan.
I started this whole thing on January 2 2021 now 11 months later I finally got to run my truck.
Every weekend that there was a race something cam up. But yesterday the track announced that they were open for practice.

So I dropped everything and tossed all my stuff in the truck and raced over to the track. It’s only ten minutes away.

There was no one there at all. I was kinda glad so I spent four hours and went through at least seven battery packs.

It was super fun to just practice jumps and trying to make perfect laps. My concentration was to be as smooth as possible and not crash. Slowly increasing speed.

I check last years winners and they can do 20-22 laps @ +~- 20 seconds per lap.

I could maybe get three or four laps before my mind wandered and I went off the track or bounced over a jump wrong.

From the video I was turning laps about 30 seconds or so. I don’t think it was bad for the first time on a track and really the first time driving the truck.

I definitely had a blast and hope to go again before the big freeze. But next year I’ll try again.

Congrats on getting out there, looks good!

I find that having some sort of goal helps with the focus. It doesn't always have to be lap time though. In fact I find that measuring practice by lap time to not always be productive. As a newbie myself, finding a smooth line usually pays the most dividends, like you mentioned. So a goal like carrying throttle through the sweeper or hitting the rhythm section cleanly always helps me. All by yourself? Music can help with focus on repetitive tasks. Just play it lowish so you can hear the car

Good luck on getting back out there soon.
