Traxxas 4-Tec Conversion

[BrianG]

Well, it's done!

I ended up ditching the front drive and totally re-doing the layout. This allowed for much better weight balance - now the center is only about 5mm off center! Aside from the batteries, all the other components are as far right as I could make them.

Total parts list and other points of interest (taken from my BL Conversions page because I'm lazy):

• Spektrum DX3r Radio
  
  
• Mamba Max ESC with the BEC disabled
  
  
• Dimension Engineering ParkBEC
  
  
• Medusa 36-50-3300 motor with added heatsinks
  
  
• Elite 3s 30C 3300mAh lipo battery
  
  
• Geared 45T spur, 15T to 26T pinion depending on desired speed
  
  
• Modified the chassis around the spur gear to allow easier gear changes
  
  
• Custom 6061-T6 aluminum motor mount
  
  
• Custom 6061-T6 aluminum top plate
  
  
• Custom 6061-T6 aluminum battery tray with lexan shield for the bottom of the battery
  
  
• Custom 1.5mm thick aluminum shield under the rear differential to protect against rocks
  
  
• Servo mounts from an Xray XT8 to mount the steering servo
  
  
• Front toe links from an Xray XT8 for the steering linkage
  
  
• Rear wing stay from a Mugen MBX5r for one of the top plate standoffs, the rest are custom cut 6061-T6 aluminum tubes
  
  
• Turnbuckle from the Traxxas Jato for a chassis brace
  
  
• Converted to 2WD to allow better placement and balance.
  
  
• Upgraded to Traxxas steel outdrives
  
  
• Upgraged to Traxxas aluminum rear axle carriers
  
  
• Moved steering assembly to the other side for more even balance
  
  
• Moved rear shock mounts to the same bolt as the body mount to allow for more ground clearance.
  
  
• Removed first gear and modified the two speed hub to be locked into second gear to enable motor braking and reverse

Anyway, here are the pics:













This last one just showing the weight balance. I don't have a scale, so a thin piece of wood will have to suffice.
