Any Ideas?
 

So I have a gen 1 supra xmod..and I have no clue on what to do with it..it runs so slow, i wish i could get liths but..theres no chance of that does anyone know what i should do?

We're going to need to know a lot more information than that to help you.

Are the batteries charged?

What motor/gearing is it using?

Is the driveline clean?

Are the wheels on too tight?

Does it have awd?

Etc...

i think i have he same problem. Same car stage one motor, two wheel drive normal batteries fully charged. But when i take off the body it runs faster. don't know why

A car will run slower once a body is put on as per the weight. I have the same body, both red and silver, and have had no problems with them. Try to make sure that no parts of the body are binding against any of the tires.

When problems like this happen you need to start asking questions to figuring it out.

First, what could the body change to cause it to go slower?

Look for friction points. Do all the tires spin equally before and after putting on the body?

Do you have the right front clip on? Do you have the chasis set to the proper length?

i checked everyhing i thought nothing was touching my gears or something inside. i took off the back clip and it worked fine. but i don't know how to play with my car without the back clip

how slow? too slow.. i got this problem when i got my first xmod evo.. im very disappointed.... i notice that the rear differential is not properly attached that cause gear sleapage... you just need to tighthen the differential.. HTH
