Dual Motors?

What lunacy is this? Has any body here done this conversion and what were your results? Sounds kind of interesting. Although it must be hell on the gears if the motors are not perfectly matched. Seams kind of a waste to have two motors and it still be 2wd. Maybe that's and idea. motor in front motor in back. Two transmissions?

The RC10-Twin starts out as a Team Associated RC10T3 Factory Team Built. The RC10-Twin factory technicians skillfully convert the stadium truck to a Twin and tune the suspension.

Factory technicians? Yeah right

The probability of other options is where the game gets interesting. Lets consider putting a 27 turn stock screamer with a hot 12 turn double. The 27 turn uses less battery but has a real high torque range. The 12 turn double has a high range of RPM. So we get the torque and rpm’s.
Lost all hope with that comment. That's not how it works. Idiots.
Changing the spur gear is the same but now we have the possibility of using different pinions on each motor. We can gear down the high RPM motor and gear up the motor that is a twisting torque monster. There are way too many configurations to discuss here. I think you get the idea!
Again...idiots

Fun factor....it may have gobs if torque, but we use a slipper to kill that torque in many cases cause we want it to put the power to the ground. If your out to cut cookies it would probably be fine, but your not gonna win any races with it.

Make one of these for the Traxxas Rustler and you have a product that will probably sell...

now I know what justalittlefaster did for a living, he was paired with justalittleliar at this company as technicians.

I put dual motors in a Schumacher Mission. One through the std transmission powering the rear wheels, one through a shorter belt to the front using another motor mount. Had to use LARGE pinions to take advantage of it. It span with one motor - it span with two!!! so gearing needed to be upped.

Lots of fun - used Tamiyas twin motor esc limiting it to x2 std black motors (25 turn I think).

G'waaaan, you know you want to... :)

I'm not dogging dual motors on awd! I have had MANY tamiya ff and ta blends making a dual motor touring car and even once a stadium truck back in the good ole days. Hella fun. But there isn't a reason for dual on a rwd, and to recommend different motors and gearing, that's just silly :shock:

Edit, I forgot I had a maxxum nose on an ultima chassis 4wd dual motor monster truck too 8)

That mount looks absolutely epic. There is nothing wrong with extreme overkill.

Might be cool to mess with. Would need some serious nose weight though.

I tried some thing along the same line with two stihl 090 chainsaws on a 6' bar with bad results. ( though I had seen pictures of similar rigs that seemed to be working). I do kind of want to mess with it but perhaps not on my new (to me) car. I think I'll keep that one stock. And yes no different toothed pinions if I do.

wasn't there an MRC monstertruck with dual moters and RWD?
I do agree that the comments on that label are 'misleading', ok, scrap that,' utter non-sense'

You're thinking of the Thunder King. Also the Baja King and Desert Thunder. They had dual motors to power them as they were ginormous for the time.

you'd be better off with a 1/8 scale brushless motor then 2 540's. less mess, mo powa!

I remember a similar add in my first RC magazine when I was 11; the June 92 issue of RCCA.

Thought it was the coolest thing ever at the time :)

I'm confused.
Is this a joke?
Is this for the original Rc10 or the T3?
Are they serious about powering a twin motor 1/10 with AA cells?
Wow.
