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?

**FighterCat57** · 05-13-2010, 08:21 AM

Nice! I really want to hear/see more positives!

What extra cooling did you add and do you have any photos?

I moved the stingers about a half degree and it's been handling well.
It depends on the battery pack weight in your boat and it's effect on the COG.

**scubasteve95** · 05-13-2010, 01:07 PM

I will post photos tonite.
Added 90 degree inlets to bearing cooler on motor mounts and used the pick-ups on the rudder and oem outlets just for them,
added 2 port flush mount pick-ups on each sponce in the rear and removed the exhaust pipes to install 1/8" rivets for the 4 outlets
(didn't want to add extra holes).....each esc and motor has its own in and out for cooling.approx 12' 1/8 water tube added
Batterys weight 1 lb each so i should be able to really dig the props down deep.

**FighterCat57** · 05-13-2010, 04:23 PM

Nice. I've got the 90's and more outlets on order and should be here shortly. I wondered why they didn't do that from the factory.

Although, there's a bunch of racers on here that cool their entire race boats with just the rudder pickup.

I'm sure they aren't running 4s through 2800kv 380 motors either.

**scubasteve95** · 05-13-2010, 04:46 PM

Ok ben,
here you go,
let me know if you want any more or something different...

**scubasteve95** · 05-13-2010, 05:06 PM

WELL I TOOK IT OUT JUST TO CHECK FLOW ON ALL THE
WATER PORTS AND WAS NOT TOO HAPPY............

VERY LITTLE TO NO FLOW AT ALL EVEN THOUGH IT KEPT EVERYTHING WITH IN THE TEMP I WANTED SORT OF
I STILL WOULD LIKE TO SEE MORE OF A WATER STREAM.
SO HERE IS THE MOD I CAME UP WITH ON THE NOT SO EFFECTIVE OSE PICK-UPS.
SLANT CUT THE EXHAUST TUBE I REMOVED AND EPOXY THEM OVER THE
PICK-UP PORTS....YEA YEA YEA I KNOW MORE DRAG.....BUT I WILL
GIVE UP ALITTLE SPEED FOR BETTER COOLING AND RELIABILITY....
MAYBE JUST MAYBE I CAN RUN THE WHOLE SET-UP ALITTLE LEANER AND MAKE UP THE SPEED LOSE AND STILL BESAFE?????????????MAYBE

**Rumdog** · 05-13-2010, 05:18 PM

That was not a good idea. If you're not running hot, why worry about extra pickups? That is going to effect the handling and speed tremendously. You want those ride pads flat and square as possible.

**FighterCat57** · 05-13-2010, 06:37 PM

More photos, run times, temps, videos, data, data, data. I love it keep it coming.

**scubasteve95** · 05-13-2010, 07:36 PM

NOT RUNNING HOT IN A VERY SAFE SET UP.
ONCE I TURN UP THE HEAT (ie TIMING, STINGER ANGLE,PROP)I AM GOING TO NEED MORE COOLING,RUNNING NOW @ MAX HEATING ON MOTORS AND ALL MOST MAX ON ESC'S @ WFO WITH ALL PERAMETERS SET @ THERE LOWEST.LETS GET SOME RUN TIME
AND SEE WHAT HAPPENS.....
I WILL SET UP A CAM SO WE CAN ALL SEE TOGETHER.BUT I STILL DON'T THINK THAT WILL EFFECT ME AS FAR AS HANDLING OR STABILITY....SPEED NOT AS SURE.

**scubasteve95** · 05-13-2010, 07:43 PM

Ben r,
what photos would you like next...i am done with the build as far as i can tell.................i have a wide aray(of photos that is)
o yea ,the pads i installed were perfectly flat and the flow was poor,
@ least i thought it was......any body else have a set installed?
How is the flow?

Bad idea IMO
this will affect the way the cat handles

**scubasteve95** · 05-13-2010, 11:07 PM

What does imo stand for?
I 'm hoping it doesn't,but like i said lets do
some testing this sunday and find out.
Cam will be rolling what ever the outcome.

**Brushless55** · 05-13-2010, 11:12 PM

In My Opinion

this will alter the way the cat handles

**scubasteve95** · 05-13-2010, 11:13 PM

O,
tune in sunday nite and we will find out

**Brushless55** · 05-13-2010, 11:17 PM

I already know what will happen

**FighterCat57** · 05-14-2010, 06:50 AM

IMO- http://tinyurl.com/24p2sjx

**FighterCat57** · 05-14-2010, 06:52 AM

PS- from the photos, you have a different battery box than what came with mine. I've also noticed that your hull/hatch appears to be different. There's a large amount of white around the hull/hatch area.

**Steven Vaccaro** · 05-14-2010, 07:11 AM

Glad your having success with 4s, but 3s is still a better setup with this boat. I don't suggest people run these motor on 4s. There are far more failures than successes. You will also find that most companies selling this have removed any info about 4s packs with this boat.

**scubasteve95** · 05-14-2010, 09:42 AM

Ben,
don't know about the battery box but the hull i painted.

**scubasteve95** · 05-14-2010, 09:48 AM

BRUSHLESS,
don't be so negitive............
I have been runnung this set-up with no for-see-able issues.
Like i said before.....why so angry

THIS IS ALL IN FUN .........REMEMBER

**scubasteve95** · 05-14-2010, 09:51 AM

steve,
thank for the concern and you are absolutly correct......but.......
having said that,what fun would it be if you can't run the stock set-up as hard
as you can with minimal tweeks to the best performance or crash and burn and then
just upgrade anyway.....

**FighterCat57** · 05-14-2010, 09:58 AM

Ah, OK, it's hard to see any detail with white when using a flash. My battery box has sides on it, restricting it to 50mm.

Do you have a current meter? I'm curious as to the amp draw on your setup.

**scubasteve95** · 05-14-2010, 10:06 AM

Sorry i do not......
Just going by heat and time...

**scubasteve95** · 05-14-2010, 10:13 AM

BATTERY BOX HAS NO SIDES...BUT
THE BATTERY WOULD STILL FIT...YEA BABY
THE BATTERY IS -----1 7/8 WIDE,5 5/8 LONG,1 1/4 HIGH
50mm,148mm,35mm

**scubasteve95** · 05-14-2010, 10:15 AM

Brushless,
have you done this under the hull pick-up before?
Do you know anybody who has?

**Steven Vaccaro** · 05-14-2010, 11:18 AM

For the reason that people will read this and run 4s and burn up stuff, then blame the manufacturer and post that the items are junk. Specifications are given for a reason, to run within the safe limits.

For example, People often email me asking if they can run 6s on a esc that has a max rating of 5s.

Why people want to pay hard earned money to beat the hell out of the items and burn them up is beyond me.

There's a few here who have tried and can probably share their experiences.

Just about anything you can think of doing with a boat... someone here has tried.
There is a good knowledge base here...

Agreed!
Lots of knowledge on this site!

**scubasteve95** · 05-14-2010, 01:51 PM

DON'T WANT TO BE A BROKEN RECORD...BUT..I AM NOT
TELLING ANYONE TO DO ANYTHING,THE MOTORS ARE RATED @ 14.4V
AND THE ESC"S ARE RATED @22.2v...SO WHY NOT GO FOR BROKE,IMO NO ONE HAS FOUND
THE OPTIMUM SET-UP FOR THIS BOAT YET.IT IS NOT IN THE FORM OF 3s THAT MUCH I CAN
TELL YOU FROM 8 BACK TO BACK 8MINS EACH WFO RUNS WITH SMALL ISSUES BEING FIXED AS THEY COME UP.
THE ELECTRONICS ARE SOUND, EVERYONE IS TRYING TO RUN THESE THINGS @ FULL TILT
RIGHT OUT OF THE BOX...SLOW AND STEDY WILL PRODUCE A FAST,RELIABLE BOAT

**scubasteve95** · 05-14-2010, 01:55 PM

I will keep looking for bottom pick up threads,if any one finds something helpful please let me know.
