River Cat twin props advise

[sampit]

The time has come were I need to buy the right props for the job?
looking for some advise
this is the setup.
twin Rivercat running 2 FC x 3126 1600KV motors
2 x long 450mm 2mm wire drives conected to 4mm threaded 70mm stubs, i also have 4mm/ 3/16 converters I could use if needed,

can any one tell me what props I would need, and how the right hand prop will stay on without winding of, do i bond the prop to the shaft on one side to stop it spinning of the shaft?
looking at 2 x 45mm props counta rotating? or can I use two standard left hand props and bond oneside on the shaft to stop it spinning of
both the stubs have the threads going the same way. do i need one with a revers thread?
hope this all makes sence.

My Shocker's shafts are both threaded the same.I have had no issues with losing anything.And I run 50mm props.

Thanks srislash

So just like running a setup I would with a single motor setup, but repeat on the other side of the hull,does that mean i can only run the props one way? and two standard props would work instead of CR props.
all very confusing.

[srislash]

Nope,you want CR so that it doesn't snake to the right all the time.You're single may do this a bit.Mine does.CR will counter react this.

Don't worry about the couplers or the threads being the same direction but do make sure they are tight.

Sam, as you know I am running same boat and setup as you and run a pair of 45mm counter rotating graupner cf props as it runs very well, if your set on using metal props Octura x442 and normal and counter rotating would also work well.
