Default Electric 1/8th circuit car

Hi

With the big increase in power from brushless motors and LoPo cells I think the time is right to come up with an electric 1/8th circuit car that will beat the IC cars.

Does anybody know what I would need to control a 3hp brushless motor and how many LiPos to have 6-10 min run time?

Thanks

Do a google search..there is a guy building one on a Serpent chassis. Aside of that, look for the user "RURC", he is the massive "electric power to duff nitro cars out" guru.

I havent the foggiest what the url is. Its been a hot minute but I know it was on another forum where I did see it. RURC has built 1/8 scale on road cars using the Seerpent chassis that do 65 miles an hour for 45 minutes straight. It wont come cheap, but the boy knows his stuff. Look him up on this forum but especially on rcuniverse in their electric thread.

Even if the motor is $300 and the batteries are around the same and then some spares with a decent charger the cost will still be less than an IC circuit car.

You need 1 engine a season or 2 plus the fuel is $50 a gallon and you get through at least one gall a weekend. It will be more expensive outlay with less running costs

I'll check out the other forums

Cheers
