Fun video! During my quest to 100 mph with my Traxxas Bandit, I learned a lot of things. My opinions below are based on goal of around 100-115 mph. I am with you, the most important thing is the LIPO. I picked up about 10 MPH using a higher end LIPO (SMC 3s 6,500 mAh "150C" LIPO vs a lower end LIPO like a Ovonic 5,200 mAh "50C" LIPO). A lot of people don't appreciate how important a higher end LIPO is for speedruns as the are used to lower end packs and think they are good enough. The difference under high load is MASSIVE. The difference between a lower end ESC like the stock Velineon ESC or a HW 120A unit and a mid level ESC (ZTW Beast Pro V2) was about 4 mph in my setup (and less likely to almost burn your car down like my Velineon ESC did - after many speedruns in the high 90 mph range). Good connectors at the motor/ESC and ESC/LIPO are also good for a few mph. I like 8mm bullets at the LIPO/ESC and 6.5 mm at the ESC/motor. Cheap, easy to solder, and flow lots of current. As for the motor, again I am with you. I was using a $40 XTeam 3665 4500kv motor and it is good for around 115 mph in my Bandit on 4s and over 100 mph on 3s (and has been bulletproof doing so). In a lighter car it would probably be good for closer to 130 mph. Sure, a higher end motor will have power but at these speeds, the motor usually isn't your biggest limitation (getting the car to be stable, getting the right tires, optimizing gearing, and running a good LIPO to me are the most important things.
Can you recommend a good Lipo battery charger for 3s through 6s for somebody not super technically advanced. Don’t need all the bells and whistles but want a good one. Love the channel keep up the good work
The way i do it is choose voltage then choose the maximum amount of capacity in high quality lipos that i can fit on the chassis. The esc and motor choice is based to the voltage, pole count and max rpm for that pole count. then shoehorn it all in and send it im pretty sure i have the fastest hobbywing powered car in the world
Batteries are super important. If you can’t deliver the power to everything then you’re never going to succeed maximum power. And set up your car properly. If it doesn’t track straight that’s a huge issue also.
If all the upgraded components are carefully selected and installed it will come down to these. Curb weight, rotational mass, aerodynamics And tire circumferance growth at speed, with least rolling resistance
The best way would be to start with a solid foundation like a HoBao chassis, unlike an Armma that has poor driveline geometry that robs power and wears out too fast. You can use brute strength to get to 100mph but 200mph is where you cannot ignore efficiency

Hey that road you use to speed run is good enough. Set up a rope at the end like they use on aircraft carriers to catch the car on a hook.
What happens if I catch the wrong car?

This is completely unrelated to this video but could you tell me how the 9.06 transmission ratio for the Kraton 8s is determined?
I did a video on gear ratios. Spur Gear divided by pinion gear multiplied by any remaining sets of gearing is the general way of doing it.
What's the going rate for a used Traxxas XO-1?
I've seen one for 600CAD
If there had to be one item i would pick esc
Tires for 225+mph. Rig up a dual XLX2 setup.
Those dual setups sound expensive, no?

What component wears and how long does it take for the wear to set in? V1 or v2?
Get with SMC and cook up the ultimate pack that can be made today. He works direct with the factory.
What does the ultimate pack need to do?
