Very nice hull, what is the lenght? I don't understand your setup, 44000 RPM unload or 22000 RPM?

The struts are very short, For big boats like yours and mine, we need approx. 130mm for stability, speed, etc...

Flex are 1/4 steped down to 3/16

Those stingers are very cool,you ccan adjust lenght they are very well build. On rhe picture it is 120mm long





A push pull rudder mount is very clean and secure, rhose parts are not easy to find, same for the T center mount at the other side

Will the prop roost hit the overhang of the boatit could possibly effect the boats ride by creating lift. Now this may effect smaller lighter boat more but just a thought.

[rscheffer]

Rpm will be 22000 (no load)
Boat length is 168 cm

This set up has been done before. http://rc-powerboat-forum.de/index.p...d=49&tid=15354
Length of te drives is 120 mm but can be made longer very easely by making longer aluminium distance blocks put infront of the strut holders.

Speed with x470 pros is aprox 90 kmh with a very goor driving time ,because this hull wants to be driven like a scale hull ca9 min total will be possible.
If i can get 4+ min on one 10 s pack each motor that can be an alternative , saving 3 kg on the boat.
Props i have to test are mbp 60 mm props 1.2 pitch.
Ps6514/3. Ps 7016 and the octura. X470

Here is the link with complete building : http://www.offshore-rc.com/forum/ind...+lipoyo&page=1

25000 or 26000 RPM is better for this hull, 22200 RPM is to low

Thanks for the link, i mailed with Laurent several times .
Sadly his englisch is as poor as my French so google translater is our comon friend.
For me the speed laurents boat drives is oke. I have other semi scale big electric boats or racing purpose.
Buster 45 mono 3060-10 4,5 min full throttle setup 105 kmh
Rpb Skatercat twin 4035-800 skorpions this is a 6 min fullthrottle setup. In this vid my buster running extremly licht en skatercat from 16 min forward

Hpr 135 and mhz mystic 138 also twin 4035-800 skorpios
All 2x10s 5000 mah setups
The 600 kv tp's will pull the bigger props and draw lower currents like the gas versions driving the mtc twins inline.
My aim is ca 90 kmh like Laurent's sv , i favor driving time for top speed.
As mine will be ca3 kg lichter and that is inkl 10Ah per motor in stead of 8Ah Laurents has.
If i want more in can always put in the 750 kv tp's , thats an easy change.

The boat on the video works very well. This is a 45", mono or twin? What is the setup and the hull?

I' m building a 50" Fountain twin setup: 4092- 930kV and 10s

The buster mono is 45 inch, i laminate these hulls my selve.
Its a redesigned razer hull , with simular driving properties but now better looking,suiteble for brushless power and much stronger then the polyester hulls and epoxy hulls comming from MHZ ,H&M etc.
My hulls are made from epoxy glas and sandwich material also on request with carbon and carbon/keflar reinforcement.
They are also used for gas racing boats, where they run extremly well.

My setup is 3060 -10 lehner schulze 32-202 2x10s5000 hyperion weight 9kg
95%full throttle in oval trim gives
Stainless 55mm mbp prop. 97kmh 5,5 min
Stainless 60 mm mbp prop 105 kmh 4.5 min
X460. 106 kmh little less then 4,5 min

Very windy conditions and second time i got her on the water http://www.youtube.com/watch?v=2yih4...e_gdata_player

Yoyo' s SV43 max speed is 97km/h . The bpat can go faster avd more powerful bthe esc are limited to 8S.
This hull need 2 x 10S or 2 x 12S, 26000 to 28000 RPM unload

Ok, may be he changed his setup recently, I will ask him or may be he told you 10S , you won' t do the same mistake

[rscheffer]

Small update , still alot of small things to do.

[Alfa Spirit]

I like the medium SV43, what is the lenght? I build an other P1 a 1 meter RAPID twin setup : 2 x SCORPION 3026 1900kV on 6S ( 40000 RPM ) but I' m not happy with the clear coat

[rscheffer]

Length total is aprox 125 , botom is 115
These hulls defenetly need painting if you want an nice finish, but because Andy ( the laminator of these hulls) is an air brusher so most hulls are shipped painted already.

I agree I own a baby SV and the hull need to be painted to get a good looking.
