Help me with a tamtech Ferrari

[olds45512]

the brushless motor you have is 1/18 scale and that esc says its for 1/18th scale so it should work fine.

[czstycor/c]

haha okay, how do you know that is a 1/18th motor?

[olds45512]

well since the car is 1/12 scale i know its not a full size 540 motor so to next size down is 1/18 scale 380 motor.

[czstycor/c]

you are amazing! how fast you think it will go?

[olds45512]

depends on the kv rating on the motor, take the motor out and see if it has any markings on it.

[olds45512]

heres the same charger

this controller is a little more but its a nicer model

i got the other remote, and charger on hobbyking.com

[olds45512]

Cool, did you figure out what kv the motor is?

[czstycor/c]

this is what the motor says
      TACON
      96M02
2303-5200KV

[olds45512]

Ok I will do some looking around for the trans ratio for that and try to figure out a rough guess for top speed.

[czstycor/c]

what does kv stand for?

[olds45512]

Kv is a rating for rpm per volt so for example if your motor has a 4000kv rating you take 4000x the amount of volts your putting into it and that's how many rpm the motor will spin with no load on it.

[olds45512]

your motor has a 5200kv rating and your lipos will top out at 8.4 volt so your looking at around 43680rpm and after some rough math your looking at around 40 mph give or take depending on gearing, that thing should be a handful to drive.

[czstycor/c]

wow, what are you using to convert rpm to mph? and these battery packs are rated at 7.4v 1800mah

[olds45512]

The 7.4 lipo will actually be 8.4v when fully charged, as far as converting rpm to mph it not that simple. You have to know transmission gear ratio, tire height, motor rpm and from there you just have to know how to convert it all to mph. It also helps that I have a friend with the same car with a little bigger system in it that tops out at 55.
