A couple of weeks ago , I picked up a few Slashes for me and my kids. We went to a private offroad track , and had a ball !! We are going tomorrow as well.
These 4 all have JR Spectrum radios, Novak 17.5 Brushless systems , and 9000T and 9000S servos , DuraTrax 4600 6 cell pack , and geared around 19 pinion with an 86 spur. With this setup , they run a lot longer than stock about 20 minutes , motor and SC barely even warm, with about the same top speed, but acceleration is slightly stronger.
Last week we all had the stock stuff, it was hard for us to tell who was who.
