Here are some pics. I get about 15 minutes on the IB 4200's. I have a 5000mah 2s lipo on the way this week, should cut the weight way down. The motor mount is from rc-monster.com. I made the pieces to hold the battery and electronics out of aluminum and I then mounted an airtronics 94359 200oz servo for the steering. The stock servos on these are usually only rated for about 60 oz which is a little weak I think for bashing. These are perfect trucks for converting to brushless because they are built like a tank and have an all medal drivetrain. Highly recommended!

I spent:

$260 for pro version of truck
$180 for Mamba Max
$90 for lipo
$15 for scrap aluminum
$35 for motor mount
$14 for hardened 14t pinion
$120 for servo-you could save some money here.

So if you look at it this way its $700, but you can go to a lesser servo or do what I did and steal the servo, radio, and mamba from a previous car.

Wow, seems like it would wheelie at the touch of the radios's trigger.

HOW FAST WOULD YOU SAY IT GOES?

IT LOOKS LIKE IT GOING 60 MPH

ANY CHANCE YOU COULD GET SOME VIDEO ON A OFF ROAD TRACK?



VERY NICE........

THIS COULD BE THE START OF A NEW CLASS. I LOVE WATCHING 10 4WD BUGGIES IN THE A-MAIN AND ONLY 3 FINISH. THIS TRUGGY IS BUILT RIGHT AND COULD FINISH A 10 MINUTE MAIN WITH OUT EVEN BREAKING A SWEAT.......

With 8 cells it is probably doing 55-60mph, I haven't clocked it, but with my 6 cell it clocked at 45mph. The motor is spinning at 73,000rpm, which is maxing it out. When I get the lipo I will take it to the track and get some video.
