Help with my first twin boat, dont know the way they should spinn and who prop

[waterproof]

Hello .

I got a new twin genesis rtr and it is my first twin motor boat.
The manual i got was from a single genesis so it do not help so mutch.
Dont understand completely how I can know that the flex spinnin right way .
Is it ok to use superglue on the flex round end where its cuttet to protect them when i pull them into the motor coupler?

Flex shafts are different , so it's a reverse and a regular but are not sure who is who and who way them must spin to not be destroyed after the first run.

Should them spin in the same direction as the wires are wrapped around the flexshaft?

Attach a pictures of them and the props, dont know where the flex or the prop should be mounted left or right and witch way the motors should spin. The motors is factory mounted.

What about the stinger (second part from the flex system) Is it a reverse of theas or is it the same?
Dosnt know if i mounted the prop right, just mounted them on, and on both prop it only stand tfl 36 19.

The flex to the right on pics have the wired spinned against right, and the left have the wires spinned against left, witch way must they spinn on the boat?
Sorry for my English and hope you understand what i Wright about.
Happy for help to get the boat on the water :)

The flex should spin so the motor pulls the wires tighter around if that makes sense. It looks like the flex on the right should go with the prop on the left, and most would rotate the props inward at the top, just like you have them in the pic.

Hello :)

Yes i understand that is important, but unsure witch way it should spin to pull the wires tighter.

I have painted on the pics so you could se.

The motor should spin the right flex should the same way as the clock? So it goes the same way that the last wire pointed like its twisted around?
The store tells me that it not like that but the other way that they are twisted so im unsure.
Motor on the left should go Counter clockwise With the flexshaft on the left on the pics?

Also a pics of the props with Paints on, i should change side on the stingers?

Do you know if the stinger (part two of the flex system) have any reverse part or is both the same?

The stingers and props are placed correctly in the picture, but you need to switch the flexes. The flex on the right should be in the prop and stinger on the left, rotating in the direction of a clock when looking from the rear of the boat.

Unsure, but now i have just change the props on the stingers and let the flex shafts stay.
When i stand behind the boat the right motor spins right and left motor spins left.

Look at the pics and see if i could mount the right part to right motor that spins to right and left parts to the left motor that spinning to left.

Very happy for that you could help me, only this thing remain and i have glue every screw and im ready to run if i just could grease and Mount the flex and prop on a right way :)

See pics, only swap the props from the last pics i post20150613_022239_resized.jpg20150613_022234_resized.jpg20150613_021502_resized_2.jpg

Now leave the shaft and the prop that is in front of it as a pair.
Now pick up the matching prop and shaft on the right side and put it on the left side (Looking at the boat from the rear) of the boat.

Props should turn inward looking from the rear,

Yes, so my prop and flex is on the right sides on my last 3 pics?
Right on Picture would fit right on the boat and spinn With the clock to right, and left flex and prop on pics would spinn anti clockwise against left?

This was not easy to understand for me, if i change side on the flex on the first pics, then the motor should spinn it the other way that the wires are twisted?
Look at my last pics, everything like before but i changed prop sides.

Should the flex spinn the same way like they are twisted or not? If it the same way like they are twisted then the pics shows it right from the beginning, or is this wrong so i must change the flex shafts?

I am surprised that no one has mentioned this yet but there are two ways you can set your props up as far as the direction they spin.

Lookng at the back of the boat your props can spin to the inside or the outside. If you set your props up to spin to the outside meaning the prop on the right will spin clockwise and the prop on the left will spin counterclockwise it will have better handling and turn better at speed.

If you set the props up to spin to the inside meaning the prop on the right will spin counterclockwise and the crop on the left will spin clockwise the boat will have more speed but it won't handle or turn as well at speed.

here is what I do:
First you need to know that there are two schools of ideas in regards to the rotations of twin props. As said , you should be looking at the transom when talking about rotation!
1. props turning "inward"= left prop is clockwise, right prop CCW
2. props turning "outward"=Left prop is CCW , right prop is clockwise
Both have characteristics that you need to experiment.
Start with No.1 school of idea. In general, Offshore racing prefers this type, however, if turning is somewhat difficult, try No.2.
Each school may need stinger (drive) angle adjustments. Each hull is different.
Now that you got this out of your way, let's look at the flex rotation. If you understand this, then you can swap many times without getting confused.
The flex is like a rope, it needs to tighten under load, that means the rotation of the motor must twist the flex tighter. To determine this, grab the prop with your right hand (wear glove or use small towel to protect your hand) and don't let it move, rotate (twist) the "motor/collet" end according to the particular prop ( rotational direction of the prop as determined by the leading edge configuration), and look at the flex winding strand direction, it must "tighten up" .
This requires a bit of visual imagination, the good news is that once you get the hang of it, you will be writing the next thread teaching the next guy who is asking the same question!

Sorry Jim, we must be typing at the same time but you beat me, I didn't mean to "override" your thread.

No, this is wrong, you will loosen the "twist strands of the flex."
Close your eyes and imagine.......

Could you quote what i said was wrong? I Close my eyes hehe but its so hard for me, first thing i see is that the way the flex wires are mounted the same way must it rotate. Maby its fault. Tryed to twist a paper but it depend if i hold it from top or bottom witch way is get stiff or witch way it came loose.

[kevinpratt823]

In my first post, I said "most would rotate the props inward at the top". I was trying to keep it simple for now just so he gets the flexes on the right props for starters.

Have you twisted towels to dry them??
Now, use only one had to twist , the other hand stay stationary...
Close you eyes.....
I don't know what to quote,,,,
You didn't say anything wrong, your concept was a bit fuzzy: need to know first why certain set ups have certain particular rotations. Then, know how to identify which flex goes into which particular prop depending on the rotation.
Just my $.02

You are absolutely right and you are right to keep it simple,
I only answered thinking on East Coast it is late, certainly I hope it wasn't insensitive to your reply....
