Schulze 160 or 300 ESC's with Lehner 3080 9wind?

[Tommy Gun]

im sure alot of you guys are sick of seeing my post lol but i jumped in over my head alittle on the big HPR and just want to make sure i do evry thing right!
so my question is can i run my HPR233 with twin Lehner 3080's in it (and decently prop'd) on 2 40.160wk escs? or would it be safer to spend double the money on the 40.303wk?

my most concern is anything catching on fire like the 4X lehner 3060 HPR 233that caught fire, and iv heard if i happen to over amp a 160 then it could pop, and while doing this a good possibility for a fire...

i am dumping about every spare cent i have to get this boat and then buy the ESCs not to mention i love these boats and wouldnt have ever got the chance to own one if it wasnt for sandy giving me such a great deal on his!

anyways these are some vids that iv found that are either running the schulze 160s or the YGE200 which is also a 200a controller if i am correct?

Blake,

Twin 3080's with 40.160's on 12S with reasonable props would be safe, but a little too much prop and poof. Although I will say this, the Schulze have good thermal control. i.e. if they heat up to much they will shut down prior to burning up.

If you stick with 10S and below, Schulze has the 32.200. Good for 200 amps, but limited to 10S.

Also remember you are going to need a lot of batteries to power that boat. Something in the order of 10,000mAh+ per motor at a minimum and that for a short run time. I believe most of the guys running big cats are running upwards of 3P and 12,000mAh+.

I'd make a build list including batteries, chargers and controllers to see if its reasonable for the pocket book. I'd hazard a guess you are looking at $5k plus just for the power system and a single set of lipos.

well i am wanting to stick with the 12s so that pushs out the 32.200, and i am almost thinking of just saving the extra cash to get the big schulze 40.303wk's

as for batteries i was planning on runing
4- 6s 1p 5000mah 45c batteries per motor
so the boat loaded up would have 8- 6s 5000mah lipo

so i would have 12s 4p 10,000mah 45c on each motor, all 8awg wiring and 8mm connections for batteries... i think that should be fine for the time being...
i may upgrade at a later time but i already have 5 of the 6s and i would like to keep my hyperion duo3 charger and not have to get a thunder power or wte just to charge and balance 10s+

let me know what you think about that set up?

Blake,

Batteries look good. I have not heard much feedback on the 40.300's good or bad. It's probably worth a couple emails or phone calls to Schulze or Etienne at ICARE to see if all the bugs have been worked out. If the the bugs are solved and the pocket book allows, definitely go for the 300's.

thanks for the info man, im just worried about burning the boat... or a $600+ esc lol i appreciate you help man thanks agn!!
ill try contacting schulze or see if i can find some 40.303 owners on here that can give me some info or advice on which way to go... but as of now id say im leaning towards the 40.303wk just may have to wait a month or so before i can buy both of them lol

or may even be able to pick up some used ones ?? that'd help alot!!

You might want to look for a thread about the 40.300 controller. The guy is a french guy who races scale cars and was using a 3060/10 motor with the 40.300 and was having major problems. Google lehner 3060/10 and see if it pops up. I just remember him being pretty darn mad at Schulze for the 40.300 speedo. And I think it is of recent but I dont remember the post dates.

I'm not into scale touring cars but this guys build took engineering to the next level. Very impressive custom vehicle! Lutach was posting as well if any of you remember him. One very smart ESC guy.

Running twin 3080s on 40-160s should be plenty. I've run a 3060/10 on a single 40-160 in a 104 cm cat on 10S without problems for three years. Remember that running twins - even on a larger boat - cuts the amp draw on each motor substantially, and allows a larger-than-usual prop.

There is nothing wrong with getting more ESC than you think you need of course. But it is never a good idea to run any ESC at its upper voltage limit. The smaller 30-volt Schulze is not suitable for 10S IME.

thats not a bad deal on that jetspin but havent heard of them or seen them in any videos has anyone ever had any experience with these??

thanks for the link!

Only seen the Jeti's in planes. Waterproofing would be pretty difficult and there size is close to if not bigger than the 40.300's

[Gerwin Brommer]

They are used in Germany.
Very easy to remove the coolers and add watercooling on top of the fet's.

I realy don't know whitch esc you should get for this big cat but I do have a 40.300 and they sure looks good.
If it was me I would spend the extra $ for the 300's for such a nice boat.
Better safety factor is hard to put a price on in my opinion.
My esc has been at Schulze for the upgrade so it does look a little different.
It now has permanent wires on the motor side + other upgrades.

Anbjørn,

Keep us updated on how she runs when yuo get her set-up. Curious on how the new mods work. My 40.160 was also recently upgraded and so far she has been rock solid.
