Motor for 4s LiPo

[Tazz]

Need a motor for E-Maxx that will run on 4s lipo. The E-Maxx is stock except for these upgrades: alum diffs and cups, steel cvds, steel center drive shafts and steel idler (single speed). This will be used for mostly bashing.

Sounds cool, a 10L would be nice.

It depends on the quality of the cells though. What is the speed you wish? about 30-35 mph?

[Tazz]

30-35 mph sounds good. The lipos I am looking at useing are 2 2S packs for $76.50 ea.

4000mah Capacity
7.4 Volts
44mm X 132mm X 13mm
Rated at 48 Amp Constant Discharge(12C)
Rated at 64 Amp Burst for 10 seconds(16C)
175 grams

Just incase anyone is wondering , this is my mostly stock E-Maxx and not custom one that I am building in the other thread (yes I have 2).

Or I my go with these For $72 ea.

6000mah Capacity
7.4 Volts
45mm X 135mm X 24mm
Rated at 60 Amp Constant Discharge
Rated at 72 Amp Burst for 10 seconds
292 grams

So the 10L will work good on 14.8v ?

The 10 L should push your around pretty good with out tearing up to much to.

I've been running a 10L in my revo on 12 cells and its the perfect bashing setup. I get nice run times and fairly good speed and it runs cool. Should be perfect for 4s lipo.

i would personally go for the 7xl. it will run cooler and just be better over all. i would also go for the second packs. there cheaper, are capable of more amps, although there are slightly bigger, they will perform better.

[Tazz]

Are the run times the same between the 10L and the 7XL?

[squeeforever]

actually the 7xl will probably give better runtimes. what kind of speeds are you looking for. you might also want to think about the 8xl.

[Serum]

10L will get you a better runtime, 10L will be easier on your drivetrain and is more than enough for bashing. The 10L will be less hard on your lipo's too.

a 7xl vs. 10l, wouldn't the 7xl draw wayy more amps than the 10L? Hence worse runtimes?

[Tazz]

I just checked and it shows that Mike is out of stock on the L motors. I wanted to place an order this week is there a Lehner motor that is comparable to the 10L? What gearing should I start with?

Definately go for the 6000mah lipos, and whether you chose the 10L or 7XL (personally I would go for the 7XL) run times will be 25-30 minutes plus

I couldn't get that much runtime out of my 7xl. I ran gp 3700 and got about 10mins. It was a fast 10 min.

When the batteries stayed in place i managed a good 15 minutes on 14 cells with the 7XL
