Hi guys,

Just wondering what Stock motors are most people using???
Whats the best to get and which ones should be avoided.
Any info appreciated, I've only run 540 before and want to try 27 turn Stock now.

Thanks

It is widely regarded that the Trinity Monster is the stock motor to have. But Trinity's new CO27 is meant to be even better having the RPM of Monster and the Torque of the P2K2, so you may want to get your hands on one

Yep, Trinity Monster Stock's the way to go at the moment, I've won alot of race's with that motor, and every race i'm in, people use bearings, which i don't, but i still beat them. Anyway you can purchase them for about $65-$70
brand new.

Cheers, Jake

bearings make no difference

Brady.Jnr

Yeah give it a Little more speed, when you know someone has bearings, there car is quiet, and if you say bearings make NO DIfferent, They r Illegal.

actually, is there really no diofference?

Jenny2004

Yes, Offroader is right. Bearings only save wear and tear on the motor, where bushing wear out and allow slop in the motor. Also some clubs allow bearings or bushings which removed the cheating aspect in the stock class, because it is sometimes difficult to see if bearings have been inserted.
Major events you will only be allowed bushings unless specified.

Anyone know when the CO27 is avalable in Australia and how much it will retail for?

Umm, bearings make a difference, and armature spining on bushings has a lot more resistance than one that is spining between two bearings, hence they are illegal at sanctioned events. Thats easily fixed though, just run the motor without any oil on the bushings for a few runs, makes them nice and loose, and fast!

Arm spinning on run-in bushings that have cut down contact area
knife edge all round or cut laterally to 'fingers' (asterisk style)
probably spin better than with ballbearings.

But those bushings don't last very long.

Bushings are fine, but they wear out quicker (create slop in the motor - not what you want), and are quite inefficient. A motor with a good set of bearings will be more efficient, but it will have more mass to accelerate from "stop" (the balls themselves, the shields, runners, etc).

Most of the top end motor tuners hone the bushings to decrease resistance of the arm spinning, and they polish the armature stack to get that little bit extra performance from the motor as well. Some of them cut down the bushings so there is less contact patch with the arm - as someone else said, this decreases resistance even more.

Some places in Australia (QLD and Tasmania are 2 that I know of - there are probably more) allow you to run bearings in stock. Note they are not states that run under AARCMCC rules. While replacing bushings with bearings when you buy a motor is a pain, it makes for a much longer lasting, more reliable motor. Bushings are soooo 1970's - why the rules still stipulate you have to run bushings is beyond me. (Of course I know the rest of the world - ROAR, etc - runs them, so we follow suit - that's fine, I don't have a problem with it, I just don't know why they stipulate them in the first place. Maybe it's a cost thing. Shrug.)

The new Trinity stock motor looks nice but it's pretty expensive compared to the monster, and apparently it's harder to work on, tune etc. Some motor tuners are not bothering with them yet. We will be stocking them soon - tuned by DC.

I usually find the motor is cactus when the bushes in my motors are at the end of there life, so I don't see the longetivity story valid, unless you never oil them (bearings need oil too). The horse power gain is not worth the effort as most people dont know how to align the bearings when doing the install of them.
I have no problem with people running bearings at club level, but I do find that it is false ecconomy for racers whom plan to race a major race meetings that carry full restrictions.

Keep in mind that it is a control motor class.

bearings in a stock motor do not belong.

this thread is about wich stock motor to use?
