just got a new kit,

Futaba 2PH 2-Channel AM/2 S3003 Servos
Tamiya R/C 540 Motor
Team Orion Super Duty Plus 3000
Futaba MC600C ESC

while testing the electrics outside the car, the motor feels underpowered and jerky,

I have tried two different motors and two different batteries with no change,

I am 100% sure that I set up the ESC correctly,

any help?

That might be the problem

a 540 doesn't have a great deal of power to start off with anyways ... but it might be something else....

I dont think it is the motor, I have tried two different ones and it is way to jerky and underpowered,

I am thinking that mabey the ESC is faulty?? (I am a noobie so I am guessing)

Faulty ESCs are usually "DOA", they just don't work.

Or they may have dead FETs, in which then the corresponding Fwd/Brake/Reverse function won't work.

600C is not reverse, right? (which leaves off the chance that your ESC is running 'reverse' when the motor goes fwd). Its not a locally-available model anyway.




Futaba 2PH (black wheel? this also not locally available) don't have endpoint adjustment, so you can't go wrong there either.

Well, you've already swapped batteries and swapped motors without any difference... why not swap in a different ESC too?


btw What are you using to charge your batteries?

Can you plug the motor directly to the battery, that should illiminate both of those things.

Carefull not to short out the battery though.

I directly connecting the battrey to the motor and it now spins much much much better, it is about 10 times faster and no jerking,

tested both batterys and motors and both are fine,

what else could it be??

Based on that it sounds very much like the speedy is not setup properly.

Have you gone through the speedy setup sequence? You need to set it up so that your radio and speedy think they have the same maximum speed and brake.

That is: When the throttle is on full the speedy knows it's full throttle and when the brak is fully on the speedy also knows that it's fully on.

Most speedie's have a one touch setup which lets you do that.

Anything like that in the manual?

Futaba 600 is the latest family, Tony.
Its just one step below Surikarn's 800.

It has all the one-step mod cons.

Ok, so it sounds like it may not be setup properly. if he isn't getting full power through the radio but is fine direct to the motor.

So should be an easy fix.
