can't wait to see some running footage of that thing. Looks sick!@RC MAN
What RC car are you doing this with? The weight and size will play a big part in the motor sizing and ESC needs.
Realistically how fast do you want to see this car go?
Have you considered how you will record speeds yet? The GPS units run around $60-80. Don't put your cell phone on the car....
You can go cheap on motors like surpass or others, but the ESC is the biggest factor in going fast. Even factory motors from Arrma are not bad (See example below in credentials). The Arrma BLX185 esc or their new smart series will stop in the 94-98 mph range with metal chassis 1/8 scale cars. This number would be higher with a lighter 1/10 on-road car.
The limits of this ESC is due to amperage limiting. Amperage limiting exists on all HobbyWing ESCs or their re-branded models like the Arrma ESCs.
Credentials for my input:
I have been 130 with the Arrma Typhon on the stock blx2050 motor.
At one point I had the worlds fastest 2 cell Limitless at 86 mph. (using a TP4050 motor)
Now building an custom car for 200+ goals.
