Default Brushless Xmod Evo (Mamba) Project



this is my project for the summer. a Castle Creations Mamba 6800kV powered 2nd Gen Xmod. this motor was just sitting around in my room gethering dust so i decided to make something.



this pic is of the mount that would house the motor: This was where i had to trim plastic away from the mount so the motor would rest level to the chassis.

Motor in mount with strap: this part was tricky, trying to get the strap to fit around the motor i ended up using some longer screws and having a space between the strap and the chassis:

next was the most difficult along with the bugs with servo centering. i had to convert a 5-wire servo into a 3-wire plug. this was done using an airplane servo:

i took it apart and looked at the circut board. it converted 5 wires to 3 so i unsoldered the 5 wires from the pot and the motor inside the servo:

i slipped the board down inbetween the slot where the AWD Drive shaft would normally sit and soldered the wires according:

Here is the whole car minus the esc and battery wired: i had a problem with the tires rubbing on the bottom of the motor, this was solved by longer screws and the hardest type of truck springs i could find.

im also trying to find a way to use the stock wire antenna instead of using the soft wire that comes on the receiver.



i may have found a way for the steering to center. using the pot from the tactic servo i used. i drilled out the sway arm from the old pot to fit the shaft on the new pot, i had to trim the shaft down about quarter inch to make it fit.



IT RUNS COMPLETELY PERFECTLY!!! HOLY **** I GOT THE STEERING TO CENTER!! YESSSSSS!!!!!!

The 1st test (ever) will be a speed test on 4 Energizer Ultimate Lithium cells. (9 effing bucks for 1 pack Dx) theyve shown a significant boost in power and speed vs alkalines. The body will be ON to help with aerodynamics and reduce drag. I have never driven this car outside because i dont live on a smooth road. So ill head out to the tennis courts soon.
