stock motors: P2K2, Co27, Monster HP ?? touring car??

[wvuviv30]

I have decided to run in the stock motor class with my TC3.

I am looking some stock motors from Trinity, and I am having some trouble deciding on which motor to get. I am looking at the Pro spec motors also.

P2K2
Co27
Monster Horsepower

P2K2: Will this one be too slow on the top end, but able to pull out of the corner quicker…

Co27: I have a question about the Co27, on their site it says it’s designed to run with the new 3800/4200 batteries. Can you run this with slightly lower rated batteries with no ill-effects to the motor? Also is this the newer Monster Horsepower?

Monster HP: Sounds like the best motor for all around racing…

I am mainly going to be running the GP3300 cells and a 72 spur. I’ll mostly be running on carpet, but every once in a while I’ll be running on asphalt.

At my local carpet oval the C027 was the motor to run. Maybe just a fad; but it seemed fast. Fantom stock motors are also a local favorite.

Racers generally use the motor that they've been able to find the tuning that gives the best results. Trinity generally has produced a stock motor that after some trial and error can easily become the track favorite. At first it was split between the Reedy MVP and Trinity P2K, now the swing is either the MS2, Epic Roar Stock or newer C027. Only way of knowing what motor is favorite or will work for you is ask the local racers, plus get ask what they are using for setup (brushes, springs) and gearing.

right now I am going to go with factory motor and then once I rebuild I'll go with upgraded brushes.

I used to run a monster stock in my X-ray FK04 and it was fast. But once I got the new CO27 motor...its so much better! It really is the top-end of the monster with a lot of torque.

What motor is this CO27? Who makes it? I still have two Monster HP motors so I may stick with them for now until I get another elec car.

[Prelude14WRX]

The CO27 motor is Trinity's new stock motor. It is the best stock motor to date IMO.

[Saboteur]

AHHHH I thought it was Corally or something like that. I'll give that a whirl sometime then.

[Grizzbob]

Yes, definitely worth trying out. I think(to my knowledge) this is the first motor Trinity(or almost any big manufacturer) has put out that actually delivers on EVERY claim thay made of it in the ads, it really can rev like a Monster, but has MUCH better low-end torque(& that also makes it easier to gear, & more beginner-friendly to boot), plus it's efficiency is very good & it actually does it all while staying cool as a cucumber, which I think is the real key to how it keep running so strong at the end of a race, no matter what batteries you use(I think the Monster & others just get a bit hot when geared right, with the batteries we use today, so their lap times can drop off a bit late in a run). Just think of the Co27 as a Reedy MVP that actually runs RIGHT, same kind of powerband(& a bit better rpm) but it actually runs cool, which was near impossible to do with the MVP(that was really it's only big weakness, very inefficient, & it ran HOT no matter what most of us tried). I definitely think it'll be the motor to beat right now.... :cool:

So you think I should just sell my monster stocks NIB and a race tuned version for one of those new guys? I'll probably just do that if I really do want to get the elec running...still waiting to hear from track events.

[Grizzbob]

Not neccessarily, you don't have to go that far, but when the time comes to replace a motor, I'd reccomend replacing it with a Co27..... :cool:

[Prelude14WRX]

If you want to be competitive...you need the C027. Every 0.1 of a second counts in racing. It dropped my lap times down...mostly because the track I race has a lot of tight turns.

[Helgaiden]

So what if im geared fairly happily with a monster stock and switch to CO27? How many teeth on the pinion will i have to adjust up or down normally?

[Prelude14WRX]

The stock gearing is a good starting point, but you can gear up a couple of teeth if you want.

For now I'm going to make use of my motors and use them up, then get to the c027. It won't help me if I haven't worked on driving skill. I mainly run nitro, nitro sedan and 8th onroad. I've ran 8th buggy for a little bit, but not as often as my onroads. The tracks were very big with some small technical parts, but not much.

Absolutely right, in order to take advantage of this motor or that one, indeed you do need to be able to drive clean, mistake-free races(in other words, you can consistently finish races without needing a corner marshal, though you might sometimes miss an apex here & there), because every time you hit something hard or have to be marshalled, you just blew any advantage your motor might've given you. Just be patient & get comfortable with what you have for now, & then when you feel ready or when a motor gets worn, then I'd put the cash down for the goodies. Now, to address Helgaiden's question, it really depends on the individual motor. I have 2 Co27's now, & depending on how they're tuned, a different gearing is needed. My first one is more of a torque beast, & as such has a bit less rpm than an average Monster, so I have to gear that one as much as 4 more teeth in the pinion(say from a 8.06:1 FDR to a 7.14:1 FDR from the Monster to that Co27), but my second one has just as much rpm as a Monster, & still has more torque to boot, so I'll gear it closer to the Monster(maybe more like 7.6:1 FDR in the same instance as the other 2 I mentioned). It just depends on how that one wants to run. But if you don't have access to a dyno to help map it all out, then I'd start at something close to your Monster, & then if it feels slow on the straight, gear up a bit at a time till it feels right.... :cool:

Cool. Thanks for the info Grizz.
