VENOM EKOS 4S 5000mah LIKE BUTTER

[scubasteve95]

OK,
I HAVE BEEN READING ALL THE THEADS ON THIS BOAT AND
I DON'T WANT TO SOUND INSENSITIVE ,I'M SURE SOME OF YOU HAVE A LEGITIMATE GRIPE WITH VENOM BUT I CAN'T BE
THE ONLY ONE THATS NOT HAVING ANY ISSUES....CAN I?ALL I DID WAS ADD SOME EXTRA COOLING.
4 RUNS WITH SAME RESULTS
4S 5000mah DLG POWER LIPOS WITH PCB 120 DEGREES SHUT DOWN
MOTORS @ 90-120 DEGREES
ESC'S @ 80-90 DEGREES
RUN TIME APPROX.8 MINS @ WFO
STINGERS @ 0 DRGREES
STOCK PROPS 36mm PLASTIC(VENOM PRO 36mm FOR NEXT RUNS)
ESC'S SET TO 0 TIMING ADVANCE
EST SPEED 45 ISH
GOTTA THANK JAMES OVER @ VENOM AND SAILOR OVER @ MINICAT RACING FOR ANSWERING ALL(ABOUT 40)
OF MY PHONE CALLS
GPS INSTALLED NOW SO I SHOULD HAVE EXACT MPH NEXT POST.
GOING TO TURN ESC'S UP AND STINGERS ABOUT 2 DEGREES NEGITIVE.
ANYBODY WITH INPUT BEFORE I DO?

How do u set timing on stock motors and esc?

How do u set timing on stock motors and esc?

ITS VERY EASY
GO TO VENOM SITE AND CLICK ON THE PICTURE OF THE EKOS
THEN CLICK DOCUMENTS
GO TO PAGE 5 AND FOLLOW THE DIRECTIONS.
I SET MY TIMING TO - 0 ADDED 6 INLETS AND OUTLETS AND
AM HAVING NO ISSUES ON 4s,BUT,
(DO NOT RUN 4s ..... JUST BECAUSE IT WORKS FOR ME)
I'M NOT SAYING DON'T BUT IF YOU DO ITS ON YOU......
JUST HAVE FUN WHAT EVER YOU DO

I may upgrade to 4s till the stockys burn out. My question is on the motor mounts those two small holes what head is that. A hex, philips, etc. Trying remove coupling but it's flush in line with motor mount. So should I unbolt motor from mount or mount from boat to get to the couplers on the shaft.

remove motor from mount,it easy with a flex shaft.
the set screw is a 1.5mm hex
i would also upgrade the cooling for 4s...6 inlets and 6 outlets
every thing stays nice and cool...
go kick some gas a$$

[Rumdog]

6 and 6? 2 esc's and 2 motors need no more than one each or the setup is too hot. Bottom line. The motors are not 4s motors. The esc's cant handle the amps. Don't do it. It's not as easy as replacing gear when it fails, A burned esc can put a hole thru the hull and damage cells and the motor with no problem. As well as leaving a big stinky smokey mess. If you want to go faster, pull the stock gear, and replace it with the appropriate stuff. A true 4s motor will be around 2000kv. Get the best esc's you can afford that will fit in your hull. It isn't worth the risk. Mr. scubasteve95 is the ONLY person around having any luck with 4s on his stock EKOS. In fact, it's quite hard to believe. Sorry.

[scubasteve95]

dont be sorry...no one cares
there are ports in the motor mount
that are not being used,a couple of 4mm
taps and your done,already had inlets and outlets,
keeping the bearing cool just seems to
make sence or no?

[scubasteve95]

Wire drive test

still running stock motors and esc's with 4s
but added pro probs and wire drives..
heres what happened.

[FighterCat57]

Jeff's wire drives are awesome!

A little odd, only 41mph w/36mm props. I get 52-54mph w/32mm props on 4s and am running 2700kv 540 size motors.

Something says you might have gotten lower KV motors from the factory, which would be a very good thing and help explain the longevity.

Make sure the prop dogs are snug against the stingers, water will pressurize the stuffing tube if there's a gap.

Very cool. Congrats on getting it setup.

[VIKOS]

Lol how does he get a lower kv motor from the factory lol. My boat runs fine on 4s. I think it's really in the props though. 32mm like what someone on her told me. Runs great with hop up couplers and jeffs flex shaft and dogs. Gona take vids next weekend of it against gas boats twice the size. Should be intresting.

If the windings are the wrong length, the kv will be off... Just a possibility. Also if the supplier ran low on stock, they might use a different batch until stock is replenished. This does happen in manufacturing. Often.

Just guessing though.

The real mystery is higher RPM and less MPH with bigger props.

I really doubt he has non-stock motors. The speed is low probably because he is over-propped. The motors can't spin up to their most efficient rpm - this is common when you go overboard on prop size. The stock EKOS motors are rather small with limited torque, made worse by the higher-than-normal voltage used. If he cut those props down to 32-33mm he'd likely pick up some speed by utilizing the higher pitch, which is what determines the top speed anyway.

I <3 fluid

[scubasteve95]

the 2 things i believe the reason are,
over prop...should be 32mm
and stingers are set alittle to neg...boat still runs slightly nose down
gunna go abit more pos on stingers..should get me to about 45max
also gotta get the 2lb of water out thats coming in..bummer
i am glad that vikos is out there so you all can see i am not the only (lucky)
person on here....o yea..vikos you also owe me a thank you....
for taking all of the abuse and name calling so we can have a clam discussion
about the ekos on 4s....
go to the other EKOS 4S 5000mah LIKE BUTTER thead and you will see what i meen(mean)

[Jeepers]

also gotta get the 2lb of water out thats coming in..bummer

no wonder nothings burned up its all under water it never gets hot

with that amount of water in side the hull could also have an effect on top speed.
