Brushless Kyosho S-RR

[Shark413]

Update:

As I was putting the conversion together I wanted to use the stock Kyosho chassis braces but they hit the can when using smaller pinions. So as I was removing the braces I noticed the motor flexed when I pressed on the side of the can. The motor mount was flexing a little and I figured this could not be good for the drivetrain. I decided to make a rear support bracket to support the motor and keep the flex down. The bracket had to provide complete support (side to side and up and down) and had to be movable so I could adjust gear mesh. I came up with a bracket that surrounds the entire motor can and also slides laterally for gear adjustments. Since I had to make a new servo mount I decided to lay the steering servo down and turned the braking servo 90 degrees for better gear access. I added a carbon fiber plate to the top of the servo mount for a place to put my rx. I then utilized the nitro motor mount holes to make a ESC mount.



Motor rear support bracket, also switched to King Headz chassis brace. Brace uses the radio box holes.

I now have most of the truggy together, I added a carbon fiber battery tray, the front and rear suspension parts. Added a Futaba FASST rx, CCBEC, Center diff with a Losi 48T wide spur, Kyosho bonded brakes. Just waiting for a Mamba Monster Max to finish.


Almost finished truggy with a Neu Energy 4s lipo and Mamba Max installed ready for a test run.


Bottom of chassis, I only drilled to additional holes, added front/rear skids. Still waiting for the side guards to arrive.


Next to the nitro ST-RR.


The rear skid has a lip that protects the alloy suspension bracket.
