Saw style runs guys, i know i know

[Brushless55]

For some reason I cannot get my UL-1 to run 5s..
It goes into some studder mode!

[longballlumber]

I hope you guys are not trying to run the stock UL-1 controller on 5S?!?!?!?!?!?!? I don't think that is what it was designed for...

[6S HYDRO]

Exactly what the title says- stock ul-1. Have been running 5s on 3 of my sv's for over a year now. As long as your careful and watch your temps, you'll be fine

[scoota]

what about the cut off voltage on the UL-1 esc its set for 12 volts , that will kill your 5s set up if your not careful . i only bring this up for the newbes thinking they can run 5s with no problems ...

[Brushless55]

if one always runs your boat till the lvc kicks in, they could be taking their batteries down to far and hurting them..
runs should always be timed..

[6S HYDRO]

I never run till cut off on 4s unless you want to puff the batts, and i would absolutely never run on 5s for more than a few laps.

I agree bro!
that's a sure way to kill lipos..

there's no way for the esc to detect over voltage. And those esc's are rated to 20 volts. Something's probably wrong w/ your 3s connector

[Brushless55]

not sure?
I even put on a BEC and still it studders..

[6S HYDRO]

Take off the bec- thats prob the problem. The stock ones handle it fine, like i said thery'r rated for 20 volts and ive been doin it on the 45a ones forever. Like i said before watch temps and short run times and you'll be fine

the BEC is not the problem just added insurance...
it did this before I put it on..
I'm thinking its my lame 12c batteries that's causing me issues..
when I run 4s I have some nice 30c packs that get me 50mph
Think I will put in an order for some good 3s packs this week, maybe zippies

[Brushless55]

Ok I tried my new 2s and 3s 30c packs and dang!
I was running a S220 prop and this boat shot out of the water and was a handfull to get to top speed.. It kept lifting the left sponson up and out of the water.. Looked cool, nuts power!

after about two minutes my UL-1 took off all by itself?
come to find out my external BEC was only rated to 3s!
and when I put 4s to it and took off the bec, some smoke came from my rx!

As far as Im concerned you are all liars unless we see some vids!!!
