Your overvolting by how much?
50% is really the limit...giving you 1100 rpm ish instead of 750 rpm .
10cm wheels @ this rpm gets you to 13 mph

[aero_storm]

Yup 50%. with 7cm wheels you get 9 mph.
*Sigh*.
I want to use 7cm wheels but its too slow. What a bore:sad:.
Oh well, my grandpa is coming down today and I will talk about it with him.

thanks,

Why work with drill motors and gearboxs?

Other options are open.

O.K. Im going to splurge on 2 1000 rpm and do you think it would be possible to chain connect it to the front wheels? Ill overvolt it by 50% and with 7cm wheels we should be off at 16mph with a lot of pushing power. Yee haw.

Please correct me if I am horrifically wrong.

The aggravation and cost of chain + sprockets to drive the rear pair of wheels should be considered.

[typhoon_driver]

why do you need a high speed?

10mph in featherweight or even heavyweight sized arenas is more than enough. The important factor is the acceleration as the arenas arent that big.

A couple of 9.6V drill motors with 7cm wheels I can tell you will give more than enough speed in an arena without touching a calculator

Got to agree with Gary on this one, P.I.T.A was around 16 MPH and was on the ragged edge of being drivable in even the largest arenas!
I have since dropped the top speed to around 12.5 MPH and its a whole lot easier to drive and still more than quick enough to deal with pretty much any machine out there.

ok :sad:.
I wont overvolt the drill, which will give me about 14mph.

Thanks :sad:

EDIT: Youre lucky I trust you more than I trust me.
