New catamaran project

[Alfa Spirit]

Hello everybody.

I stoped RC offshore for a long time, my last boat is a Key Biscayne from Graupner with Ultra 1600 Marine motor powered by 20 Ni-Cd cells.Actually I sell it on Ebay, here' s a picture



Now I will build a Head of the River catamaran, motor supplied with Lipo 6S batteries ( 2x3)

I ordered the 32" fibreglass catamaran hull, an aluminum rudder and strut, Xpower motor 540 XL size 1510Kv 60A, a 60 mm water Cooling Jacket, a Xpower 540 Adjustable motor mount and a Himodel GX 200 Amp speed controller. This one will be modified for water colling

Do you have any comment about this setup ?

Thanks

[Alfa Spirit]

Here are 32" hull and parts

Is it necessary to rigidify the bottom of the hull? :

[screwball]

i think that a great start good luck with the build!!!

[Raydee]

Looks like you did your homework. Just remember that a 1510kv motor on 6s is a mildly hot setup and to prop small to start and keep your run times short until you are confident that the setup doesn't run to hot. Good luck and keep the build pics coming.

Where did you get the hardware from? ( The inline setup )

you should have gotten these

any duel drive system cats I have seen dont have that type of mount especialy since you have 74mm long motors those legs on the mount will not work...the ones i sent you a link to will work


ooops sorry I thought you were going dual but you are not so that mount will work fine

[domwilson]

Nick, it is good to have that info. in case others may want to run dual drives.
Thanks for posting that.

I don' t understand what kind of problem with that motor mount

[Jesse J]

I don't either, very nice looking mount. The problem was if you were running twin set up. Since you are not, no worries. Can't wait to see more, carry on!

[norbique]

I agree, for a single drive cat that motor mount is totally fine. Nice one.

[JCAustralia]

As long as it fits under the hatch there should be no problem......

Just make sure the motor plus the water cooler does not rub against the hatch when its closed.....

Nice motor mount, it kinda looks similar to the Etti ones that OSE sells.....

Good luck

I see a problem...

The bottom of the part the motor mounts directly to has a v shape. Cat hulls are generally flat, or very close to it in the tunnel.

That won't fit unless you block up the sides.

Or just turn over the center piece that holds the motor and reattach it to the sides

[tth]

Like Rockworks said just turn over the middle section.

[Jesse J]

good eye rockwerks

[ozzie-crawl]

edit as well, yea does look like the etti one were you can flip the centre for cat or mono etc

[ED66677]

EDIT... yes turn it up side down!

[Jesse J]

I was going to order one just cause they are so beautiful, but $11 + $8 international fee + $5 shipping? am I reading French right? $24?

Too bad, I would have liked one. Why can't they pick either international fee or shipping cost?

I paid 10 US$ including shipping cost for this Xpower 540 Adjustable Aluminum Motor Mount. In fact looks very nice aluminium spare part, I think this one will be OK. So, I' ll post pictures when my orders will be at home

[Jesse J]

Thanks Nick, you gotta be the quickest searcher on eBay, or .... something.

Yes, Alfa watching your build, looks interesting

[Alfa Spirit]

@ Jesse j : Is it yours? Very nice looking cat

What kind of hull is this? Looks like the Bittburger from Precision in Perfection.

[sailr]

It is made for a Vee hull. The floor in your cat is FLAT.

I don' t understand what kind of problem with that motor mount

[Alfa Spirit]
