My mini lst's little run time run time (7-8min) is finally getting to me. I just rebuilt and lubricated the F/R and center diffs and checked for grinding and the run time didn't have any noticable increase. Does anyone have a clue what the problem is, or any suggestions? Thanks.

Racing T

is your mini LST stock??

zach brenner

thats the run time when it is stock, get a thunder power 2000 pro-lite 2 cell
it will get you 15-20 min and it will go 4 mph faster

yeah that would be a nice up-grade, but when my mlst was stock the battery last 13-15mins. 7-8 minutes sounds very short.

Kokopelli06

Yes Racing T it is stock.

Zach, thanks for the suggestion, but for now, im dont want to buy a lipo because then ill have to buy a charger, and i dont have enough money for bouth right now.

Racing T

you should check for any binding in the drivetrain,

Are you using the included charger?

zach brenner

what charge rate do you charge at? if it is to high(over 1.5) you might have ruined the pack and thats why.
a good alternative to a lipo is a team orion 1600

I have one and it gets about 15 min.
this is again probably out of your buget but save for a low kv brushless motor, that will bring your run time up.
a mamba 4200kv and that 1600 will get 20min

Dokioto

Something is wrong. My Mini LST is mostly stock and I get 15 to 20 minuets of run time. What charger are you using? I would suggest that you get a nice peak charger.

Kokopelli06

Inverted and Dokioto, i use a Duratrax IntelliPeak pulse charger.
Zack, i've already started saving for one
and Racing T i checked and theres no binding

Oh and also, will the bl motor runtime shorten if i add more cells for more voltage (7-8 cell pack)?

zach brenner

if the new cells are around 1500, no
but if your going to add up to 8 cells it will weigh it down and be a pain.
my setup is a mamba 25 w/ a 9200 kv c4 motor geared way down on a 6 cell 1600 mah battery. it goes about 35-40 mph
if you want even more power get a 3 cell lipo along with the bl system it would go 73mph.(then get air born)

Kokopelli06

How long would the runtime be with a mamba 5400kv motor and 1400maH and 1500maH cells?

zach brenner

depends on how you drive if your a lead foot like me, 16 min if you go easy, 20-25min

zach brenner

I know i guy who runs an 8000 mah lipo in an rc18b, 90 mins baby!

Kokopelli06

yea im a lead foot too 90 mins?! Has he ever driven it for 90 min straight?

Dokioto

How many amps do you charge you battery at?

Kokopelli06

at about 1.1 amps

-Inverted-

Wow thats terrible.

Dokioto

What battery are you using, stock? I don't know why you are getting 8 minuets of run time.... I use a Duratrax IntelliPeak pulse charger and charge at 1 amp and I get around 15 minuets. Are you using full throttle all the time? I don't use full throttle a lot so that could be why I get more run time.

Kokopelli06

yeah im using the stock battery and most of the time im full throttle

Dokioto

Then thats probably why you only have 8 minuets of run time. I don't have much room to drive the truck in the winter, so I can't go full throttle ,most of the time....

zach brenner

on race day he drove all day in the parking lot, ran down at the end of the day

Kokopelli06

Haha thats awesome. Does it overheat or harm the electronics and the motor to run it that long?

zach brenner

no it's like the enegizer bunny.
