Default 27 turn stock motors..?

Going to enter a class at a new club, but I usually have raced only tamiya (GT tune) so I have no idea about 27 turn motors.

Sorry, I wasn't very specific was I!  I just want a recommendation of one for racing. Also, what kind of gearing?

Gearing all depends on your track, and your car, but as far as a motor goes. The Trinity C027 PRO really is an incredible motor. Ive got one, and i have yet to find a stock motor faster.

Im guessing that your racing sedan and if so just start with a stock cobalt, there is so much that you can do with these motors its crazy, but as it goes cobalts genarally have more torque, monster horsepowers have more top end, Epic X usually has more mid to top from my findings

The track where i will be racing seems to have a long straight. It seems that the monster would win out.

The cobalt is a 19turn motor or do you mean the CO27?

I would go to the track, watch some of the stock races, find out what the fast guys are running, and get that

I think i saw you post this on racechat a day back or so in the West London forum. For gearing on a ROAR i'd start at 6 overall as that is a good place to start for UK tracks with purple + spring and red - spring. For motors i'd recommend TeamScream/eXpress (UK). Jeremy (TeamScream/eXpress) is a good person to deal with (phone him up as the website isn't updated a lot ) . If you order brushes from Jeremy (teamscream UK website) either get the H1 brushes or X1 brushes. If you can get the Red power brush break in drops as they really seem to stop as much wear and don't gumm the motor up half way through a run, just 1 drop on each brush. Run it in then put it in the car and race.

6 Overall? Over what; rollout, final gear ratio, what? Every car is different internal gearing too. TeamScream/eXpress, aren't they just a motor tuner? Which motor?

Yes they are a motor tuner but i recommend them as they are very reliable when i've dealt with them. As i said use and gear a ROAR motor at 6 (final gear ratio)

6 is way too high. It will never spool up fast enough and you will get lots of comm wear and it will run way too hot reducing efficiency, etc. Co27 can handle the most gear, and in most cases shouldn't be more than about 6.2. Even 6.2 is really rare. Medium to large track about 6.5, tight as low as 7.0 or lower. Monster is RPM motor, 7.1-7.5, never higher.
