New catamaran project

[rockwerks]

One suggestion for these HiModels: watercool & change the capacitors, they are way to small for this capacity...

Or just add more caps

[CornelP]

Been there... the original ones are a bit of a suspicious origin. But yes, adding more will take the strain from the ones fitted.

I' m waiting for motor, cooling jacket and aluminium motor mount from rcworldwide.com.hk, they aren' t very fast ...

Now, I' m preparing the hull: reinforcement inside, tight box filled with floating material, exhaust pipes , and soft design modifications ...
After I' ll do the paint job

[Alfa Spirit]

that may work, if you can run your stuffer tube all the way into the strut

That work fine with bigger teflon washers and brass tube inside the strut, That' s perfect. With the Graupner drive dog I can use 3/16" propellers without adapter

I think that' s the best solution for HOTR 4mm strut. Easy, cheap

i had a crack in my 4mm and caused the shaft to spin in side the square , so i got a octura 3/16 bearing drilled out the strut and and installed, very easy to do and no adapter and easy to remove shaft to clean, just like every other setup is

The XPower 540 XL / 3674 11 turns, 1510 RPM/Volt arrived today The motor looks a very high quality

Aluminium motor mount from RCworldwide is a very nice part

[elvish]

Hey,
Nice to hear news from you,
Any updates on the build?

[Alfa Spirit]

I whent to RC shops but I didn' t find carbon. So I bought fiber glass layers and epoxy.
I' ll first reinforce the joint around the hull and after the bottom and sides with two thicknesses of fiberglass
The aluminum rudder from HOTR was badly mounted (inverted). Now it' s OK, All screws are on the same side and rudder is perfectly perpendicular to the cat

XPOWER 540 XL BRUSHLESS DATA SHEET

Gee, the 8XL is the same specs as Feigo. I wonder how close they are? I do like the pinned motor end.

Where dio you get this from? I have seen several distributors.

I bought mine here . Those motors are made by FSD Motors

[CornelP]

XPower and Feigao are pretty much the same... at least the same factory. When one of my suppliers placed the order for some XL's, he was asked if he wants Feigao or XP... Actually, if the order is consistent, you could get your own logo and color.

[Jeff Wohlt]

Yep...FSD or some plant like makes them both.

[Alfa Spirit]

Now I' ve got all parts to make a nice job

I bought an ETTI water cooling plate for my HiModel GX 200
