Guys com down,

Don't worry, get the mamba 5700 and order some tought kimbrough gears,

Make sure to set the mesh correctly and use plenty of thread lock,

Next make sure you set up ur car right, Then Dail into the mamba with the USB and set the throttle curve to low!,

After, u might want to change ur tires to HPI rubber, If not get normal rimz and tires and before glueing leave out the

Insert and get a PVC peice and put it under the tires.
