I purchased a Kyosho ST-RR a few months back to replace my tired CEN TR Arena. I added an O.S. 28xz, JP-4 pipe, 300 oz servo, FASST, etc. The thing was so much better than my TR. Longer chassis, big bore shocks, chormoly drivetrain parts, excellent handling and powerful. It was the only nitro vechicle I actually drove, everything else was brushless (E-Revo, 1/8 buggy, Jammin CRT.5, Stadium truck). So after I split two fuel tanks and almost burned up my truggy, I thought about converting it to brushless and switching between nitro and brushless was throwing my driving off as well. The O.S. 28xz is an amazing engine so I had to have a good brushless motor I picked a Neu 1515 1y. I picked up a spare chassis on E-Bay and started the conversion. After turning my CEN brushless truggy chassis into swiss cheese I wanted to minimize the number of additional holes I had to put in the chassis. For all my previous conversions I used my own custom built motor mounts, this was mainly so I could set the motor back a little so I could use the mech brakes. For this conversion I decided to use the RC-Monster mount and a motor spacer. I only had to drill two additional holes in the chassis.
