sv27 GPS Speeds!!

Cheaper still is to tear those Propel packs down and install battery bars. Believe me, It makes a big difference.

Its the cell itself. Its nuts to buy them when good IB3600 packs are the same price. I have tryed a lot of differnt cells. The IB3600 is the toughest cell, that stands up and does not fail like the 4200's. Well its getting hard to find them now anyway. Cant argue with this, just toyin around...running 6 cell IB3600 packs and a M445. The even 7 cell propel wont touch this. http://s110.photobucket.com/albums/n...t=MVI_1389.flv

PS this exact boat is avail on Ebay http://cgi.ebay.com/ws/eBayISAPI.dll...MESE:IT&ih=020

I think i am going to go back to lipo. I thought these propel batts were the best on earth as for being a NIMH batt. I figured i could use the heavyness of the batteries to adjust the CG. I do need to adjust my trim tabs. My turn fin is directly vertical. Side fins are cocked back a lil.

[supervee1981]

YES DOMWILSON the link of the propel batterys are the ones i got but mine were custom built and are 7 cell not 6. The guy did a awesome job. Heres the ebay guy who sells them

GET INCREDABLE RUN TIME!!!!!!!!


GET LONG-LONG-LONG RUN TIME & 45MPH+ ROOSTERTAIL POWER!

DONT TAKE CHANCES BUYING FROM SELLERS WITH LESSER FEEDBACK RATINGS! SEE MY 100% POSITIVE RATING FROM OVER 1430 BUYERS!



YOU WILL GET 2 OF THESE GREAT BATTERY'S W/ DEANS PLUGS INSTALLED

SEVERAL OF MY CUSTOMERS HAVE WENT OVER 47MPH WITH THEIR SUPERVEE 27'S RUNNING THESE DUAL 8.4V PRO-RACER PACKS!




THESE ARE A PERFECT FIT IN THE SUPERVEE 27!

maybe you need to move the batteries closer to the transom.

[supervee1981]

i moved them all over the place. The problem is im not running lipo's and these packs are weak. Also...weak packs and they weigh 15oz a piece. I can run 7.4v lipo packs 4000mah which weigh 7.90z a piece. I think thats the best way, along with tweaking the turn fins and stuff.

i think you are selling yourself short by just assuming that nimh is the problem. i've gone 45mph with my sv and that was using 14cell nimh. lipos will give you more speed, but if you are only doing 28mph on nimh, the batteries are the least of your problems. things may not be trimmed out right... you might also try and find a way to borrow another set of nimh of a different brand and see how those work.

those batteries are surely contributing, but i would be really surprised to see that they rob you of 10mph in speed just because they are lower quality cells.

bottom line, be fair to yourself, and try your boat on a good set of nimh before you spend a huge chunk of change on lipos only to find out your boat is still slow. you need something to compare your "norm" to.

[fastbaltek]

i couldnt have said it better. mine boogies on 14 cells on a balanced 640 and lightly sharpened. when i first got it, it ran wet. maybe you need to make sure the strut is at 0 degree or parallel to the bottem of the boat, few degrees off makes a lot of difference.

[pacificstr75]

I would also say that the problem is your battery. I used it before & the result is very poor. They even over heat after i used it. So maybe try the IB or GP batteries if your not ready to go lipo yet...

[Eyekandyboats]

i am pretty sure those batteries are the problem.

Ran my friend Jeff's SV27 today,after doing a few mods for him
Motor esc stock
Batts IB4200 12 cells
Mods are strut angle 2deg down angle
battery placement
and mod X642 prop

first run was 41.5 mph
second run on same cell packs 41.8 mph

you have to excuse pics quality taken on cheap camera phone

Not bad at all for the stock components. Actually better then most! I'm still waiting for things to thaw out here in Wisconsin for my maiden voyage. I got 2 new boats near x-mas so I'm getting very impatient! Actually I finished the first one like the same day the water froze last fall then I got a new SV for christmas. The only advantage is I've had lots of time to set them up the way I want for spring.

[supervee1981]

well i ran my 7.4 2S 4000mah packs today and i got 32.8mph on the garmin.

Stock motor
stock esc
Graupner CF45
scuffed bottom
tabs 2 degrees negative
rudder cocked in all the way towards the transom
1 turn fin on each side stock supervee ones...angled back for loose driving

[supervee1981]

if i run the same setup listed above does anyone know if its worth getting a fiagao 7XL (2,328kv) or the ammo (2,300kv)?

they both are the same price practically......

stock motor is 1,700kv = 27,000rpm
fiagao and ammo 2,300kv = 36,800rpm assuming you are running 16volts (16cell) or 4S.

anyone have any suggestions on this idea that everyone usually does or any experienced boaters?

The 7Xl or ammo would work but you will probably need a new ESC,
For the size prop you are running i would try the 8XL.


For the 32.8mph run where you running 2s2p or 4s1p setup ?
