Genesis catamaran ???

[justintime2w8]

Three emails back and forth and I could not pry dimensions out of them.
You will find my post on here last week begging someone for them.
If those work, $375 and you will have super scale drives and rudder.

[tiqueman]

I was just looking at them.. Im not convinced theyd work yet. I wonder why they wont talk?

[justintime2w8]

Yea seems like critical info for for someone attempting to purchase their stuff. My neu's and turnigy 180's are sitting here waiting for a home....

Haha.. Nice

Yeah youd think theyd share... wierd

[FighterCat57]

I have one of those on a mini rio. Those are waay too small. For micro set ups.

Ooops. They looked like they would fit the transom space. Not much space!
Isn't 3mm the same size drive at the KOS uses in it's twin setup? (I guess that is too small! )

Are you talking about this model?

If I don' t find long stingers I' ll build something like this. Motor ==> flex collet ==> flex shaft ==> flex collet ==> shaft with sterntube

[Jeff Wohlt]

That will work fine....even a little neg angle will not hurt it a bit.

if anybody is going twins maybe try the twin drives hotr offers from there twin boat

too small

[justintime2w8]

Way too short, there is not enough height clearance for the props. Need to get them past the transom, about 3 3/4 in. total.

[FighterCat57]

How about using a two bolt strut with wire drives? They are smaller struts, but the wire drives will strengthen the cable setup for more power in less tube space. Jeff makes the wire drives for the 4mm prop shaft. I have a pair in the EKOS.

Just a thought.

Those are 1.25" long. That would be an awful lot of unsupported shaft to get out to the transom. And as Justin said, you have to get out that far so the props clear the overhang.

I was actually thinking transom mounted, not sponson transom mounted. Run the tube out of the sponson transom and to the transom mounted strut hanger. Since there is enough space on the transom for these smaller strut mounts.

Again, just a thought, but don't see why it wouldn't work.

Gotcha... it could possibly work. Just looking at it again... it may do it.

[Jeff Wohlt]

If you do struts they will adjust easily. Ever thought of a two piece stuffing tube lined with teflon? You leave about about 1/2" of liner exposed closer to the transom and then easy to adjust... Since wires do not beat around so hard it works very smoothly.

Can you explain that a little more?

[Alfa Spirit]

What is negative angle? Propeller higher or lower?

[ED66677]

negative angle = prop pointing down 1 or 2°

[Alfa Spirit]

The Genesis hull arrived this morning, very good finish, fiberglass is very strong, a very nice product, really

[Alfa Spirit]

I' ve found the stingers for a twin setup, they are avalaible at RC Raceboats Shop in Germany.
CNC made, running with ball bearings, parts anodized, with right or left hand motion that 3,2mm Flexshaft. Supply effected completely installs, with brass wave pipe, ptfe pipe and stuck together Flexshaft (please when ordering absolutely select the direction of rotation). Measures: Overall length inclusive wave: approx. 135mm Flange measures: approx. 15x25mm

[Rumdog]

Nice! These sure are good looking cats!

Don't go 1/8" it will break all the time.

Jesse J uses those powertrims, His advice is welcome

Size is perfect for Genesis cat

[ED66677]

I think I'm going to buid some cheap one with adjustable lengh for the french market!

[Alfa Spirit]

What do you think about this twin setup?

- FSD 540XL / 8 Turns, 2075kV

- Kintec Racing water jacket because it' s same color than motor ...;-)

- HIFEI Swordfish 120A or Turnigy 120A esc

- 2x4S or 2x5S LiPo batteries

[ED66677]

under 4S a 8XL is perfect but for such a big hull I would go for 9XL instead, so you can spin slightly bigger prop and evantually go for 5S more safely than with a 8XL!

[Alfa Spirit]

Merci my friend 2x5S with 2x 540XL/ 9 Turns (1845 kV) is the best choice?

[ED66677]

it's not the best it is just a different view, I would go for 4S and target 30000rpm unloaded, some other guys here on this board would go for 32000rpm and a bit more!
so you have 3 possible setup with the given data's :
8XL/4S you'll spin 42mm prop reasonably 43,5 max as this will be a twin
9XL/4S you'll spin easily 45mm prop IMO the best choice for the best prop efficiency
9XL/5S you'll spin smaller prop than under 4S but I've no idea, it's gonna scream
remember that you will use counter rotating prop (and left and right flex) so choose the setup according to the brand of prop and the size available in that brand

[Simon.O.]

Have you considered some of the bigger outrunners and feeding them with up to 6S.
I am assuming you have not bought any of the power system yet and this may be an option.
I am no master of outrunners as I have yet to get my next two OR powered cats wet. They do seem like a good option and there are a lot to choose from.
