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

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

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

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

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.
Now I' ve got all parts to make a nice job
I bought an ETTI water cooling plate for my HiModel GX 200

Hi,
I' m not sure that flex/shat coupling will be strong enough.
I think to reinforce the end of the square flex cable with strong glue Is it a good idea? Thanks

Hi Alfa Spirit,
your project is very impressive for me. Im going to build this cat either.
On picture above i can see very nice prop in fitted in graupner DD. As i remeber, graupners DD has outer dia. 10mm and to props seem to be perfectly aligned with DD. Octura has about 8mm hub dia. So i prefer props like yours. Where does your prop come from?
Thanks, Cugi.
it will hold just fine, glue will not add to its strenght ,Hi,

Ok, thanks Elvish
The aluminium propeller is a USA brand may be AMPS or something like that. No brand on the prop, only 2029

Hi,
I have just modded my original TFL strut because I might be getting the dual motor set from e-bay, The problem with this is that it runs 4mm stingers and I want to use 3/16" prop's...
I turned down a piece of oil-lite brass 4mmI/D and 4.762 O/D. It's a lovely snug fit now and runs true.
I think this is the way to go if you want to use 3/16 props on any 4mm shaft.... IMO!!
