I don't really think the Reedy Sonics are known to be one of the faster spec motors. Spec racing is always going to a motor of the week situation, unless the rules change. I say if you want to be successful, look into one of the known "fast" motors. That being said, good drivers carry more corner speed, which may seem why the fast guys seem to pull you down the strait. Have one of the good drivers at your track see what they think of your cars power.

Understood, and maybe my fault for giving more information than I needed too. Top speed aside what I really want to know is, if there is a "tell" for when it's time to rebuild a motor, is it worth rebuilding a motor? I see the parts for sale but figured the experts here would could give me a practical answer.

Thanks in advance.

There are some tells for when a rotor goes bad as motor does not have any rip anymore and gets really hot with your "old" gearing but that could be bad bearings as well.

This past Saturday I switched it up and went 30/76 and its everything I need to run with the big boys at my local track.

Motor temps for the day never exceeded 95 degrees and the high temp was 78 degrees for the day.

Here is a link of that race for reference (and its my first time being recorded) with out my mistakes I would have been in the battle for 1st!

I went to www.teamnovak.com and couldn't find the gearing recommendation chart under Tech Info or elsewhere, and a search for gearing, chart, or anything else resulted in no hits (I could find pinion gears, however).

Also, gearchart.com doesn't have TLR22 under the pulldowns, but they do have the XXX BK2 on there. So the new racer will need to research the transition ratio.

So while I absolutely agree that people need to understand gearing, I think there may be better tools.

Page 33 of the TLR22 manual (http://www.tlracing.com/ProdInfo/Fil...022_manual.PDF) has a tailored gearing chart for the buggy for 6.5, 7.5, 8.5, 9.5, 10.5, 13.5, and 17.5 motors.
