Jason- Thanks for the report. Use stiffer springs, add sway bars, add graphite arms to prevent traction roll. In other words go stiffer.
LRP X12 3.5
This motor has been performing very well, in pan car and touring car, but breathed its last, Sunday a week ago. I probably have 40 runs on it. Now here are the gory details. When you open the back of this motor to oil that rear bearing you cannot even see it. It is hidden by the sensor board and then the solder tab board which is soldered right to the coils. No access. Well I have never had a rear Brushless rear bearing fail so I let it slide. Last week the rear bearing exploded, locked the rotor and fractured the magnet. The car came to a halt.
See this post to see an easier way to oil this rear bearing.

The procedure to oil the rear bearing is to remove the front can and bearing assembly and the rotor and then oil it from inside. My motor has just the outer race glue in place inside now, so the the motor is totaled. I can't get it out without unsoldering the windings. I don't care to do that often, although I have done it successfully.
New motors are on the way including a Tekin 3.5 sensored for the pan car which is also using a Tekin R8 speed control.
Front bearing on a 3.5 are a different story especially on the pan car. They fail often. They need new lube every session or two. They need to be checked by hand every 3-4 sessions.
Sometimes when you lose a front bearing in a bad spot like on the straight at full throttle, you can lose the whole electrical system, speed control fry's leads pop off the battery cells. Motor sensors are destroyed. This is quite expensive, so oil those puppies up and on the LRP X12 pull that arm after 30 runs or so and oil that rear bearing.
Novak and LRP 3.5 motors are not very equivalent. The Novak Ballistic is much easier to service. The Novak motor has gone softer on power and RPM, though. The LRP is much more like the early Novak HV's with good power and RPM. Each has a suitable track. The Novak still will not run with the Tekin R8 speed control.
I ran an X11 today. I think it was .3 slower than the X12 but it it hard to tell. The Losi was still faster than 3 of 4 of the other touring cars that showed. Poor traction helped the Losi XXX-S. It gripped better than the rest.
