Watercat 1300 Patrol 1:10 scale brushless twin-jet
« on: October 06, 2008, 10:26:26 PM »

Hi & greetings from Nordic!

Here is our new project, for me it is first scratch-built also,
scale model of of new Finnish Frontier Guard patrol boat,
PV06E, or commercially now named Watercat 1300 Patrol.

It is scale 1:10, length 146cm, construction is conventional plywood,
fiberglassed surface.

We have 2 of them under construction,Olli is working on nr 1 wich is equipped with CY 26ccm gasoline
single jet-drive, mine is having twin outrunner 10-pole Flyware motors.

Both of them are having 40mm Kehrer Power Jet propulsions

Best regards,

Hannu

Wonderful  models  Hannu,  please  keep  us updated  on  the  build.

( They look a bit like the Strathclyde Police Boat )

Thanks, fellows!

Well, in matter of drawings, sorry,they dont exist yet,  building is based on pdf file of PV06E Watercat -prototype, Napa - ship design software lay-outs and bunch of
fotos taken from Coast Guard station at Nauvo, Finland.
Ofcourse those files are available

Yeap, it looks a bit similar than Clyde police,PV06E is  Twin waterjet equipped with 2 x Scania Di12 66M, 478kW, achieving +40KTS speed.

Jets are Rolls Royce FF 375

Hull design is following a lot to Marine Alutech´s earlier products of Pilot & SAR boats, this is new Finnish Coast Guard patrol boat,
there is 13 of these ordered and under construction now.

Here is shipyard webpage:

Hello,

Here few pics of brushless outrunner motors. Only way to make cooling for outrunner is to watercool motormount, its 360 deg water circulated,
as well as ESC´s ( both motor & ESC are in same circuit, it looks to be enough at least for now)

Motors are from Flyware, type T-REX40-500kv 10-pole outrunners, max amp rate apprx 100/130A at 56volts, weight is 900grams

ESC´s I have used are either watercooled Schulze 160WK or Sentilon 100A 12S (marinated flight esc).

Hannu

Hello, I'm the other guy who's building this gasoline version. The status at the moment is such that action in water starts to be very good, and I'm gonna start building details.

Hello,

Here is some videoclips of Watercat early sea trials,still a lot to do for finetuning ::)

http://www.youtube.com/watch?v=YQx7kOKoQ_M
http://www.youtube.com/watch?v=luDI53Fr6Pc

At 10S 6000mAh lipo packs(2x10pces) static load is only 47amps, giving output some 1.7KW / motor , totalling apprx 3,4KW/4,6hp

GPS measured top speed for now with early trials showed 45kmh/24.3KTS

Hi, Proteus

Here is link to Kehrer jets

http://www.jet-drive.de/cms/component/option,com_virtuemart/page,shop.browse/category_id,11/Itemid,17/

This Power-Jet 40 is only one from Kehrer´s products, wich can handle higher power levels, EP is running now around 13.000rpm,
as top limit for jet is said to be apprx 15.000rpm

For a single-jet gasoline version jet end tunnel tube and reverse bucket is already modified, I still have original Castoldi ones,
but in next weeks we will make new test pices for end tunnel and reverse buckets, as Watercat uses RollsRoyce FFjets, wich are
totally different from Kehrer´s, so a lot of scale mods must be done. Hopefully we could also get with modifications a bit more efficiency out from jets

Hi Hannu,

I'm working my way through the same sort of boat at 1/12 scale and am experimenting with home made 375S drives using plumbing fittings for the main rotor housing and inlet. The nozzle etc. is from electroformed copper to approx 1mm thick and the steering nozle will be the same.
My main problem is the reversing bucket which does not seem to fit any of the KaMeWa patterns.

I've attached a photo of the real one for information and, hopefully, ideas on what the bottom of the bucket looks like?
I've also attached photos of the project sofar.

Good Luck

Tony

Thanks Hannu,

What I'm looking for is a photo of the bottom of the reversing bucket. Is it open or partly closed?

Hello, & greetings from Pickala pond, had a great time today  with 2 watercats, Olli´s gasoline powered was showing after keel modification
to be extreme agile %%

Here is some videos about Watercat´s "cousin" from  Sweden, called Stridsbåt 90 ( Combat boat), very similar hull design/power etc, running with FF410 jets

Tony, here is a link where you can find pictures of waterjets' underside. The buckets are partially closed, as you thought.
