Watts is watts?

Are you saying a 1930 accelerates a car slower than a larger 2400 given the same motor RPM and same gear ratio and same wheel size?

[Serum]

no, The car felt more nimble on an XL2400 than on the 2250

Oh right. Sorry, wasn't familiar with LMT model numbers. :)

That's interesting! And good to know...

Are you talking about Mike Cronan here?

Are you saying he uses a 1930 in a maxx size truck or something? I thought that motor was slightly too small? If my memory serves me right.

This still doesn't seem logical to me though, i mean there is enough torque to flip over backwards several times over.

When you say more 'nimble', do you mean like more 'spaztic', more 'hyper', more like a kid that hasn't had it's ritalin? Something like that? I'm KINDA understanding what you mean now.... well, maybe :032: :005:

Yeah, Mike Cronin used a 1930 in one of his race-maxxes. he loved it. Now he uses a large Neu though, to get a tad more torque and run a bit cooler.

Search for the movie Viruss posted of his lightning powered by a 1930, it does wheelies with a centerdiff. It's got the torque !

Hey Serum, I searched and found the thread, but there the link for the movie is dead.

Does anyone by any chance have another link for the same video?

thanks

Okay, i see..
Well, i just looked on my computer, and i don't have it either.

Here, check this;

the movie that says 'bl revo' is powered by a 1930 and 4S lipo.

Well, this was a crash course. All of the information was very enlightening and I now have more of an idea of just how much it is that I don't yet understand.

Thanks.

sjcrss used a 1920 in his maxx for a long time....it did wheelie's on command no prob....that motor was small too! Still was not as fast as my xl though...

[Serum]

Your XL was a league on its own!

[neweuser]

very true! he had better temps than I did too. i was very surprised to say the least in the performance in that motor in the heavy of a truck....

[Serum]

yeah, they work miracles. No doubt.

[zeropointbug]

I wouldn't doubt it, it's just the temprature problem, trying to keep those little demons down to a decent temp. How hot did it run? and how fast?

I remember lot's of ppl used to use Lehner Basic's, they went pretty dang fast too, about 35mph tops.

IMO, I think we can, and should be using small motors... it's just a matter of getting the most ideal turns, voltage, and efficiency curve. I've seen the Lehner motors have much different eff. curves with diff # turns/voltage. EX. The 3080/40t on 100 volts has VERY higher efficiency at lower torques, and drops off slightly as you increase current (torque); the same 3080 with 15 turns running 50 volts has fairly low efficiency at lower torques (current), but gradually increaes as you up the current. It all depends on what is required more, and what kind of duty cycle is observed, like acceleration/cruising to get the best AVERAGE efficiency, thus power consumption.

But really, as long as a motor is suitably sized, you will have very decent efficiency, if you want to go the extra mile and score a few % points, for extra runtime, or cooler running, or less weight due to less batteries needed, or whatever. That's what makes this sport so addicting :004: , and frustrating at times :031:

geez, i thought the 1930 was almost too small, now I hear the 1920 :005:
