A silver can that turns 14,500 at 5v will turn 20,000 or slightly more at 7.2 v I know cause I,ve got 2 that do that. A motor that turns 19,000 at 7.2v will be in the low 13000s. Your 2 standards do not compute either theoretically or on the test stand. You need to revisit your specs and make it one or the other. Would suggest keeping the 5v. standard and eliminate the 7.2v standard.

Agreed, I have 2 motors that are in the mid 13's and both turn just over 20K @7.2

I just gave you one that will do that easily. Hated to do it, but since fumble fingers dropped your good motor, felt I should replace it with a better one.
If the silver can standards remain the same, there are going to be a lot of people over the standard. I've got one motor that turns 18900 and you can't have that one.
No point in letting you borrow the second one as they are now illegal.

I'm fairly sure the silver can rules apply for all classes using that specific motor.

And remember guys, it's not MY rule here. I'm just relaying information. I'll check with the big honcho tomorrow.

Is that 18000 at 7.2v???? If it is, you ruined the motor by water dipping it. A black can fresh out of the box with 5-10 min. of running will turn 24,000 plus. After the brushes are fully seated, it will be in the 23,000 range. With some wear on the brushes rpms will be in the 22,000 range. I'm talking about an untuned black can at 7.2v. I don't have a ton of experience with black cans and can only speak of the 4 black cans I have, which are the new one with the marshmellow brushes.

It would be too late in the season to make them now, hence we had them made a few months back.

I recall a couple of iterations for the Nats motors last year. However, we are running out of time. I'd like to know what motors to bring to the dance. Guess I may just have to bring a mixed handful and see what's legal come Saturday morning. I don't have an "official" motor checker, so I'll be guessing up until that time.

But now to the more important question........To wad up my brushless GT2, or not to wad up my brushless GT2.......?????

Cool Motor limits!

Maybe Fred means that you can't go over both limits to be legal, i.e. if you go over the 15,000@5v. then you can't go over 20,[email protected] and if you go over 20,[email protected] then you can't go over the 15,000@5v. If you go over both limits then the motor is not legal ! Larrio, correct me if I'm wrong!
