How do I get the SS to go 50-60 mph? I really need to know soon!

WOW.....That's some pretty hefty speed there. I would start with a brushless motor and an electronic speed control, for a motor like that you will need a novak super rooster esc and a 3000mah battery (make sure the battery has high voltage cells). Even then though I don't know about 50-60 mph. Hope this helps.

P.S. Let us know how you make out.

Very easy to get that speed but you will need a low turn motor and a good esc. Slightly larger tires would also work well. And if you wanna get a brushless motor you have to get a special speed control, not a novak rooster.

What kind of esc do you need for a brushless motor? I know you would need pretty powerful one but I figured the Super Rooster would get the job done.

You have to use a special one made especially for brushless motors...

So with the right stuff how fast could you get one of these things to go??

60-70 mph. Maybe more if you geared it right. Check out www.modeltech.co.uk to find the brushless motors. They are very expensive, over 400 dollars. Here's an equation I use to figure an estimate of speed.

(((rpm/gear ratio) x tire circumference x 60)/12)/5280

all you need is 200.00 dollars to blow and you can get it to go 60 easy do as i did 8 turn motor, super rooster, and 10 cell batt and your set only one problem you only get 5 min run time and 5 runs to the set of brushes

How's the handling with something that fast?

Don't turn or you get to pick up 500 pieces of traxxas car. ****

well if you have 120,000 rpms (best brushless) with the motor/drivetrain ratio of 1:1 (yea right!) then theoreticlly you should pull 215 mph. Going that fast, your tires would seperate from the wheels, the drivetrain would shatter, and, when you turned, it would be 10000 piece pick-up. HA. This estimate is just based on bobmon69's speed caculator. A 215 mph SS hmmmmmm....

The calculation is right. But the highest a brushless will go is 100,000 rpm because of the speed control setting. No one in the right mind would have a 1:1 gear ratio with any motor. You would just waste your money to blow up a motor. And if you got a brushless for $400 then you would definetly not wanna blow it up right away.
