Hi all. New to Stock motors, my previous electric experience is with the closed endbell motors per local track rules. I'm branching out to 1/12 4 cell stock and ordered a Trinity CO27 Pro motor. Then I read a magazine review and it said the motor was "optimized" for the new 3800+ batteries. I'm still running the 3300's (3500+ mah/ 1.189 volts on the matching labels), will the CO27/3300 combination work?

TIA

I still run 3300's for some of my practice packs. I can't get the lap times I can get with the 3800's. I'm about .3 to .5 a lap off after about 2 minutes into the pack with a CO27. Run time is still there.

Default CO27 and Battery Choice

I've been running CO27's this summer on ProMatchRacing 3800 packs (1.207 V / 2.3 IR and 1.217 / 1.8 IR) and the better the battery, the better punch (IR) and speed (V) I see. Driving a BMI TC3 with good electronics on a 112 x 76 foot asphalt course with some tight sections and fast sections (a lot of on/off throttle) I use about 2300 to 2400 mAH so runtime will not be the issue. I expect you'll get more punch and speed with new batteries but other than that you should be ok... I think the only possible issue is your batteries might get a little hotter if they have a lot of IR (if too hot to keep your hand on them, they are getting too hot) but even that probably won't be a problem (I have used my 4.5 brushless with junk batteries and only when really hard on the throttle was it too much).

You will be fine. With the High voltages of the 3800's the CO27 was designed to handle these high loads, so with your 3300's your motor will be just fine.

I'm in the market for some really long lasting, easy on the comm brushes. After doing some searching, it seems like the Orion enduros and the Trinity XXX brushes are recommended.

My questions are...... Which will make more power? And is there a significant brush/comm life difference between the two?

It would be great to hear some real world experience.... thank guys.

Default Brushes easy on comm

I found 3002 brush to be easier on the comm than most, with decent power (not the very top but good on CO27 and I've heard they are better on Epic X-stock) and it lasts a while (not 20-50 runs probably but for me it was cheaper per run than XXX).

Big Jim recommended 766 for club racing but I've never tried them. I THINK the 729 might be the same one (has Reedy part number 766)??? Sorry no real world experience there.

your choice but i would use the Big Jim's Alignment tool or slide a brush through the hood (while its off the can) and use it to the align the hoods.

Check out Team Br00ds "New Brush Hood Alignment Tool". It is all machined stainless steel.

Hi guys need some advise on stock motors, hoping someone will be able to help.
On the week end I ran on a very large track (used to race 1/5 cars on) and used 2 motors a CO27 and X stock, first I ran the X stock as it is a revvy motor and thought it would be the one for this track, the FDR was 5.37, the motor was good but not great, overall I ran 3 X stocks that day all with the same overall result, all motors were running F brushes.
Then I switched to a CO27 with a FDR of 5.03 and it was slightly quicker, i know the FDR will give me a bit more top end but I thought the X stock would have been a bit quicker around this large track.
Im a bit confussed and if any one can help me to get the X stock up to speed please do.
Chris

Has anyone tried the KOS-27 EVO 30 motor from Integy? Can someone give me advice on springs and brushes? Is the KOS a roar legal motor? Thanks.

The 30 degree motor is junk....the brushes take a year and two moons to break in......and the springs don't sit very well....and no, its not, nor will it ever be ROAR legal....

The zero degree version is very good though.....the Co27 is the motor to run, with the X stock making a decent impression....

Hey guys, I am going to be running 1/10 touring stock class at the local club. Track layout is pretty small 60'x40' or there about. They got ozite carpet (1 year old) and allow the smelly stuff for traction compound, so it seems pretty high grip. I am running a ft tc4, last year I used the monster stock and at the end of the winter season I used the co27. I have never had the chance of using a good tuned motor though. Is there really that big a difference between the trinity pro motors and the tuned motors by brOOd et al? Anyways season starts up next month and I am looking to get some motors and suggested rollouts or fdr's for them.
