I had converted a CEN Arena truggy to brushless awhile back. It was crazy fast but I was not happy with the brake modulation and battery perfomance. I sold that truggy and concentrated on converting my 1/8 buggy and CRT.5, which were lighter vehicles and would be easier to convert. I had such great success with those conversions, especially getting the mechanical brakes working, that I decided to convert another truggy. I had a second CEN truggy that was not being used. I stripped it down and started to figure out what I needed and where everything would go. First I needed to make a special motor mount that set the motor back so that it would clear the disc brakes. I could have used the combo RC-Monster mount I had with a spacer to move the motor back, but I decided to make a custom mount that was separate from the center diff mount. I then replaced the CEN center diff with a Kyosho diff. I added Kyosho bonded semi-metalic brake pads/rotors. I cut and formed the new motor mount and drilled all the holes I needed to mount it. Coming up next I will add the motor, ESC, carbon fiber batt tray and brake servo.

Here is my previous brushless truggy, it used motor braking. I sold this one a while back.

Here is the aluminum bar I used to create the motor mount.

Here is the rough motor mount being test fitted. I needed to get it close to the diff so I could use small pinions, but it also had to clear the brake rotor.

Here is the mount and motor/pinion being test fitted.

Top view showing fit of motor, brakes and center diff. It is extremely important to keep everything parallel when using a separate motor mount.

Motor = Neu 1515 1Y or Feigao 8XL
Battery = Maxamps 4s2p 6000mah
ESC = MM
Diffs = front/rear CEN diffs with cross pin mod
Center diff = Kyosho with plastic 46T spur
Battery tray = custom carbon fiber
