    esc and dual motors

    i hvae a 12 turn esc and i want to run dual motors what do i have to do like i see that if i connect it in on way it will add the turns of the motor but in another way it will subtract the turns and i was wondering howmany turns this motor hascklik me

    You need to wire the motors in series. Unfortuneately, I'm not too sure how you do that...

    Wiring in series will supposedly double your runtime and torque at the expense of speed. The torque has been disputed, though (the motors tend to stall out more?), so most crawlers run their motors in parallel and still have plenty of power left over.

    If you're serious about running dual motors (I don't know why), then I'd invest in a Super Rooster or XR and run the max cells you can on Titans, a Mag Mayhem, the Permax, or maybe the Integy 55-turn lathe motors.

    Here is an article with wiring diagrams.

    When wiring in series, add motor turns together. For example, two 20-turn motors in series would be the equivalent of one 40-turn motor to the ESC.

    When wiring in parallel, divide the motor turns by 2. For example, two 20-turn motors in parallel would be the equivalent of one 10-turn motor to the ESC.

    You'll be limited to dual 24-turns in parallel, obviously.

    In your pic, the motors are actually in series. This setup would give you 7.2V going to the ESC, but the motors would only get 3.6V each.

    You could get a Novak Super Duty XR and wire the batteries in parallel and the motors in series. This setup would give you 14.4V to the ESC with 7.2V to each motor. This is how I run my Clodbuster!

    As for motors, almost all stock motors are 27 turns. The Tamiya 540 motor is a 30 turn IIRC. There is also a wide range of pro stock type motors on the market, these can be found in almost any number of turns you desire!

    Hope that helps... and good luck!

    Yep, your picture shows your batteries in parallel and your motors in series.
    It didn't have enough power... so, I rewired it!

    You could run a set up similar to the E-Maxx which would give you LOTS of torque and speed - remember the E-Maxx is about 5 lbs heavier than the 'pede and the E-Maxx will do 30(ish) MPH on dual 7-cell packs... I expect the 'pede with a similar set up would be getting closer to 35-40 MPH...

    So if you can get an Novak EVX ESC cheap you sure can get the 550 Johnson motors cheap (less than $5 a piece surplus)

    Gonna need a wheelie bar too

    How would you mount the second motor?

    i am going 4x4 so i need as low of cost as possoble
    ok i noticed this i should know this because i am on a eletrical class in school


    i think this is right

    Only one problem with that. Your picture states that the ESC has a seven cell limit. You are going to be running either 12 or 14 cells through it. Unless those batteries are only 3 in a pack.

    if i run them in series it will double the mah but keep the voltage at 7.2

    Nope, if you run the battery packs in series it will double the voltage & the capacity will stay the same. You need to run the packs in parallel to keep the voltage the same & increase the capacity. Personally, I'd just run one pack at a time.

    I think that before you attemp this modification, you should get a little more comfortable DC current. Also, get a book or something on how parallel and series are used on incoming and outgoing setups. Im not trying to be mean, its just that learning something correctly the first time is always a much better approach.
