Yep I've read & heard about installing trays in place of the radio box etc. But I thought the whole idea of the radio box was to help with keeping things dry if - heaven forbid - the boat filled with water. And I'm guessing removing the radio box alogether would definitely kill my warranty.

Working on sealing the boat now as it happens. I layered on a healthy dose of silicone over all the internal screws etc as well as the drive shaft exit point. Hopefully won't leak now.

Can you play around with the positioning of the ESC with the replacement trays? I'm thinking I'd still have more or less the same problem if the ESC was still in the same location.

I too would remove the radio box. You must tape the hatch closed. In order to do so remove the latch lock. This will seal the hull off. Water proofing the receiver and servos will help in case the hull fills up after being damaged.

Hi everyone; just a follow-up on my SV27 experiments this Summer.

Running 3S2P (two 3s batteries in parallel) + Prather S215 prop, my average max speed was right around 25MPH. That's a good "fun" speed and the 4000 LiPo's last forever. Motor ran a little hot but not too much; ESC just a little warm.

Well at the end of this season, my motor was starting to go (bearings) and Idecided to have some fun. Running the same setup as 6S1P (two 3s batteries in series), I was getting up to 36.7MPH on the stock motor. Was.

That's because I toasted the motor. Not a big deal, it was bad anyway. The leads coming out of the motor were so hot, that they melted the tygon tubing that comes out from the cooling jacket. This wasn't the reason for the melt-down however; I could still blow through the tubing fine after it was all done. The motor spins freely so I tossed it out.

So next year, as long as my ESC is still good, I'll either get a bigger boat and use that motor in the SV27, or just use the Neu Motor Ihad pulled out. Iwas flipping the boat a lot with the Neu Motor however, where the stock SV27 motor was on the edge. 37MPH was a nice, just barely-controllable speed.

Surface water temp was 62F.

That means...no 6S on the stock motor lol!

esc is only rated to 18v so it may be toasted as well. 37mph on 6s seems very very low.
Something seems off.On 4s and grim 42x55 I was hitting low 40s on my SV with the old blue can motor and pushing close to 50mph on 4s with a ul1 motor. The sv does have tenedency to flip easy, if properly setup though it runs very well.

Agreed with what was mentioned. Dump the radio box and waterproof the rx. Replaced the radio box with something like the kintec servo mount kithttp://kintecracing.com/Supervee_27_upgrades.htmljust scroll down and you should see it.

The pic is ul1 power (motor/esc), but you get the idea.

It might be the prop size; I went down in pitch so Iwouldn't do-in the ESC. I'm using an aftermarket ESC by the way; so hopefully that is still OK. 50 MPH is pretty impressive; it must look like a rocket taking off. I'll watch your video shortly.

even with less pitch you should be upper 40's to mid 50's on 6s with that motor
I've run mine several times on 5s and see low 50's with no heat issues at all on a 42mm prop

Ok thanks; it was an old motor (2 years of heavy running) and maybe it was worse-off than I previously thought.

Low 50s on 4s...Not stock though.http://www.youtube.com/watch?v=6JSwz6hiRwc

I gave(yes gave) that boat away earlier this year. She was setup about as good as you can setup a SV. Lot's of work on that hull.

Default RE: Super Tune Your Super Vee 27

I did a bunch of changes over the Winter, and the old SV27 lives on. 

I took the water pickup on the steering rudder and use that to just cool the ESC now off the port side.  I added a traditional tube pickup to cool my replacement Neu motor, a 1415-2Y  (1100kV) on the starboard side.

With the old S215 (mild) prop, I'm getting 15.1 MPH wired for 3S2P and 32.0 MPH wired for 6S1P.  The high voltage seems to be helping efficiency quite a bit; the aftermarket ESC is barely warm at all now and the motor is just a little warmer than the ESC.  I run pretty much wide open the whole time.  It might be the dual water cooling setup, but either way I'm good when the water temps here hit 80F+.  My cheap LiPo batteries still get hot, but not too hot to hold onto after a continuous run.

According to the OSE calculator, I'm dead-on 32 MPH if I use 92% motor efficiency.  So now I'm debating whether I should go with a bigger prop, or just keep this setup which can run back-to-back battery swaps all day with hot intake water.

I could go for a bigger prop like the S220 (36 MPH), S225 (41 MPH), or S230 (45 MPH) but am not sure at what speed you can get to before it becomes uncontrollable.  If you have any suggestions let me know...

I would go with the S225
your only runing at about 24,420rpms and that's low on 6s so the 225 would be no biggie for your setup

Considering selling my SV27 and all the lipos, props, mini GPS if anyone is interested. Haven't used it in 2 years....and want to find her a good home. See pics for all included.

Upgrades from kintec racing include-
ammo motor 36-50 2300 kv with water jacket
60 AMP marine esc from aquacraft
adjustable trim tabs
water pickup off trim tabs
dual turn fins
cowl latch upgrade
liposhield
(6) hyperion lipos battteries- 25c/500mah
(2 )hyperion AC/DC charger/dishchargers
servo mount upgrade
velcro straps for batteries
Tactic 2.4ghz radio/receiver
10 propellers (3 S220's/octura 440/3 and more)
Multiple bullet nuts for prop
Garmin GPS to measure speeds velcros to top of ESC
Infrared duratraxx temp guage
Speed grease for prop shaft[img]
tape for hatch (need to do this every time) Once flipped, takes in no water if taped right and shaft greased properly.
original operation manual for SV and battery [/img]chargers

Last speed test was 49.7 mph with octura 440/3 prop with heavy nose down(trimmed for stability). did not test the prather s/220's as I haven't used since I bought and balanced them.

Whole package with add-ons, gos, chargers and all is valued at over $700 easily. Make an offer

Thanks for the tip on the S225; I ordered two to experiment with.  It should be interesting how close I end up to 41 MPH.

Unrelated to this, the prop shaft pulled out a few days ago and the water took out my old ESC.  Oh well, the new one I ordered can do 8S if needed and has an option to limit RPM (which I would need to do on 8S) in the future.

Last update until I get some new LiPo batteries later this season.  My 30C 4000's are getting old and running too hot for comfort.  (I'm only getting about 2500mAh on a charge.)

On 6S @1100kV, I'm now getting 38 MPH on the S225 and 32 MPH on the S215 if you round the decimal points down.  This is with a new ESC as well; my second Swordfish 120 died due to getting wet so I went with the Hobbywing SeaKing 120 and gained a little with only 7.5 degrees of timing.  If anything though, it's probably due to the fact that the SeaKing is about 30 grams lighter.

One thing I noticed is that in the low 30's, the bow bounces occasionally with my batteries set forward but not too bad.  As the speed increases near 40, it bounces quite easily and there are times the boat is out of the water more than in...looks like it's flying!  In theory, I could go 8S and probably match srt10's 55 MPH, but that must be pretty hairy at that speed.  I haven't had to go swimming or have Dad start up the big boat so I'm pretty happy now with the reliability at least.

Hey guy"s i also did the same changes two new water pickups , extra water port,extra turn fin,the prop and motor are stock.The boat always ran great with the batt pos. for cog.But now at top end it rocks from side to side at a fast rate. you have to get off the throttle some times to settle it down.the new turn fin is set to match the old one.
Anyone got any ideas?????????

your CG could be a little loose
try moving your batteries about 1/2" forward and see if that helps

It was only the second time out since the new parts added. after the first run i found the motor loose in the mount thought that might have been the problem. does the angle of the turn fins make any difference? and what angle works the best?
I will have to try moving the batteries

srt10,

With new batteries (old ones were puffing) I am getting 41mph on the S225 prop.  So that worked out pretty well.  The S215 is around 37mph most of the time and is a fun overall prop.  The S225 will sometimes cause a few barrel rolls and seemingly random flips, but that adds some excitement once you get over 40mph doesn't it.

Diesel6401,

I did get the same Grimracer 42x55 props that you mentioned above to see what happens to my speed.  I do like Stainless props (stronger and safe to work on), but these Grimracer props are pre-balanced and polished for the most part.  I am waiting on some new prop nuts, but once I get those it will be interesting to see what happens.

Hey Grimracer... is there any real advantage to polishing the prop? Wouldnt it have more bite in the water unpolished sort of like sscuffing the bottom to decrease surface tension? Ive heard some say to just leave it alone and concentrate more on detongueing it and sharpen and balance it.... just curious of your opinion.

Angry wipeout. 3660SL 3180kv

So i slapped a 3660SL 3180kv Brushless Inrunner (WaterCooled) on my aquacraft with an x60 amp esc. with one 3200 mah 11.1v Li-Po, Grimracer 42x55 prop and the following was the result.
