Default brushless systems runtime

I am wondering which bl system will give you the best run time out of the novak,neo, and mamba.

Find out which one has the slowest motor/lowest amp draw.

it will depend far more on batteries and gearing. if you under or worse yet over gear it will heat up the esc and thermal shut down until it kools off. when you get your gearing right and some high end 4200 or 4300 should get 15min. to 20min in bashing sense, but track running like racing 10 to 12 minutes. with a lipo that would change.

I thought we were comparing brushless motor systems to each other, not batteries and gearing. If you wanna really complicate things, tires, bodies, wind speed and direction...this could go on forever...but I'm pretty sure his question was as I anwsered it, which brushless system is most efficient.

I am asking, which system will run the longest w/ equal setup, equal batteries, equal car, close to the same motor. I am just trying to figure out which will give me the best run times for lipo/brushless truck racing. I am not one of the kids who comes on here and doesn't know what he is talking about. I am asking which one gives the best run time when properly setup. I guess as far as motors are concerned I will be running a gtb 6.5, or max 5600, or the neo equivalent. Now, if you want to talk about batteries and run times then I'm sure you can find a forum to talk about that as well.

Party, I doubt there's anyone that really has a real answer.

Someone would have to have done some extensive testing with all three systems to know what the differences are.

Seat of the pants guessing or "wow I can run for like 20 minutes in my yard...." is most common on these threads.

I have run several MM systems, an old Novak, and an LRP sphere comp... but I just race, I don't track all the data so I have no idea.

There shouldn't be a significant difference between the Mamba 5700, Novak 6.5, or Reedy 3 star in either power or runtime.

I have the 5800 Novak and with 3300 Sanyo I get 25 mintue run times on a small track

Cheers

that is why i mentioned the battery stuff it is going to have far more to do with runtime than the brand. i would say your only looking at like a minute or so of difference in each one. so it will be which company your loyal too as to which you buy.
not to have some clown respond the way he did to my first reply. the gearing is important in that you dont have a thermal shut down by overheating the esc from misgearing. wind and bodies wont have anything to do with that.

When used with equivalent motors I doubt there is any significant difference. I think the LRP has some punch control features, and running a low punch control setting could help you gain run time, but you're obviously giving up something. Novak doesnt feature this in brushless mode because you can really do the same thing with exponential, more so with brushless than with brushed because with brushed you are pulsing the power to the motor through the brushes where as with a brushless motor it is pulsing the electromagnets themselves in sequence.

What kind of differance are people getting in run time comparing something like a mamba 7700 and a 5600?
