VENOM EKOS 4S 5000mah LIKE BUTTER

[VIKOS]

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.

If he's running 36mm pro machined and i'm running 32mm pro machined, my props are gona pull more RPM's than his. His will produce more torque but also drain more amps to produce power..Take off will be quicker than mine but top speed will be slower..

[VIKOS]

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)

I don't judge nor make opinions outloud...I how ever really wanted to see if 4s was possible and it is. If your running WOT till your batterys die then your crazy cause cooling is no where near as good as say mid throttle which I feel is the issue with most that have burnt up something. I will take videos today of the run so you all can see..first will be 3s then I'll do the 4s..I have no GPS so I'm not even going to guess speed but you will see the difference, I was shocked. oh on 4s 3200mah that is...don't want to run longer power incase but my 3s are 4000mah with great run time indeed...Just sucks when power is dead and the boat barely turns to make it back to shore.

WOT...YES INDEED,
motors run coolest and most efficent @wot i have found.
plus i added all kinds of extra cooling.
4s 5000mah i am getting 15-20 mins now with the venom charger compared to
the 8 mins on the other charger i was using
and thats beat you don't have a gps i was hoping you could give
me your top speed and i could compare it to mine.you using 32mm
and me using 36mm prop,i am betting you could go wot
for a couple of seconds to get it.also can you tell me your run
time on the 4s?just need someone to compare numbers against..thanx

[scubasteve95]

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.

dude ... now thats funny....

[VIKOS]

ok I'll check run times...ran the boat a second time on 4s and ran fine..way to much chop the boat kept bouncing..I could clearly see the red props every time she passed by...which is why Ithink the shaft came on done. A coupler set screw got flung out of the hole,put everything back together locktite this time gona run her this morning soon as my packs balance...welll with 2 WOT runs and one half throttle pass my motors are no where as hot when I use to run WOT throttle...but again you have additional cooling on the boat so that might also be why..my skipping was not allowing for good cooling even with 0 degree trim she still hopped...even flipped it and kept going. My friend took the video on his HTC EVO trying to figure out how to send it so I can post it. I might go to radio shack and buy a GPS since there pretty cheap these days and take some speed runs.To scared to put my GPS application from my iPhone in there and lose my phone lol....

[scubasteve95]

vikos,
go on ebay to get your gps..
got mine for 20 bucks delivered brand new(garmin gecko 101)
gives max speed, time and alot of other stuff.....fits nice and neat to.

[forescott]

Where are you mounting your gps? I have the little garmin forerunner that I usually mount with velcro in front of the battery tray. But recently found that I can pick up a little speed by shoving my gps in the back between the fake little exaust ports. Its a tight squeeze but I gained a couple mph because I changed the c.o.g. slightly. Food for thought!

[VIKOS]

Good spot but that's where most of the water collects. But this would help with skipping on wot gottah try that. Thanks steve

Yeah, the gps is supposed to be water proof up to 3m. Unfortunately theres not much room in the ekos to adjust the center of gravity with the batteries (even if you remove the trays)

[VIKOS]

Well careful placement of Velcro in the rear will help that alot. Gona check radio shack for a gps or officemax

[scubasteve95]

i have mine same place forescott shows his but the rear is
a good idea...once i finish all my tests i will try in rear and
see what changes....
any issuses with signal back there?
the window up front gives alittle view of the sky...maybe its
not needed..(the window that is)

[forescott]

I like the window because I can bring it in and check the top speed without un-taping the hatch!

[VIKOS]

I just don't like the way the window likes to fog with moisture in side makes me thing electronics are getting wet. But hull tape is amazing I must say. My stingers are at -1 or -2 no reading just trial and error but I doubt it'll make a difference in choppy conditions. Boat will still skip. Hey Scott I'm surprised ur not running on 4s with ur set up. Or are u. Are those 9xl u got running. This Saturday will be the 5th time she runs on 4s with no issues other than a coupler screw coming undone and shaft sliding out part way. How is a piece of silicone cooling tube sopost to help from not losing a shaft anyways.

[forescott]

I do run 4s most of the time. I use my cf-40's that have gotten me 55.2mph so far on 4s. I do like to use 3s when I want good run times and less heat.
