Can I buy a good ESC / Motor, restrict the speed (using thottle hi point in my remote) to train my fingers and setup my car, then gradually increase the thottle hi point when my fingers are more capable and the car is properly set up?
I did it successfully with my Mini-Z, not sure if there is any difference in 1 / 10
so my current idea is to use a 2nd hand LRP Sphere TC and a 4.5t sensored brushless motor on my F104. I know it will be toooooooo fast if I use the ESC and motor at 100%. My plan is to set the throttle hipoint lower to slow down it to a manageable speed.
Is there any bad thing about this setup? will the throttle response be less linear? will the lifespan of the ESC / motor be affected?
Price is not a concern because the ESC and motor are 2nd hand.
The torque/power between slower and faster motor is different. Higher turn motors (13.5 or 10.5) has less torque or acceleration out of a corner, while lower turn motors (5.5 or 4.5) is very powerful throughout the whole rpm range.
The top speed you can control using hi-point of your remote, but the power of the motor, you cannot.
back to your question: assuming with 7.4v with a f104, DO NOT use 4.5t. you will NEVER need that much power for a f104. i suggest at most a 8.5t/10.5t. (most people use 13.5 or 17.5)
You can use gearing to lower the torque, but it only affects just a little bit. The motor will get hotter because the motor need to work harder with a larger pinion.
Other than F104, are you going to play something else?
You will have a very hard time playing F1 with a 4.5T. For most 2WD/RWD cars, too much motor power will be extremely hard to control. A 4.5T motor is already very fast for touring cars.
if the esc fits in the chassis and under the body, you can use tc spec in a F1.
