Stuffing tube

[Kram]

Hehe!

When i mount the two stingers, should i keep the brass tube or teflon liner some cm or mm outside the hull? Like when you ser the genesis form the rear, you can see the tubes outside the hul... my english is not that good... haha

The brass tubing comes thru to the outside of the hull and mounts inside the strut, mounted on the transom. The length of the tube depends on the strut hardware you use. Inside the boat also depends on the hardware you choose. Some ESC mounts have a stuffing box support. The stuffing box support can be separate from the ESC mount.

Search on this site for the hull type you have. Folks have posted pictures of their builds to give you a sense of what to do. If you're not the mechanical/fabricator type, then you should really look to a RTR boat to start and get hands on experience. For most of us, figuring it out IS the fun of the sport!

I tried to look at genesis builds, but i cant see what they did with the tube outside the hull.

I have two 110mm stingers, and when i put the tube inside the stinger, the tube will be many cm outside the hull... is that right? 😆

running liners in both my boats but I am very strict on greasing the shafts after every 2 or 3 runs.
I have a twin electric mono and its liners are snug on the drive shafts and I grease them up allot also.
I heard a while back somebody say that the liner makes the boat quieter.
not sure how true that is cause I have never run any of my boats with no liner.
And yes I have brass tubes with .187 cable

Should liners be snug in the brass tube, I think yes but I have melted the end of one of my liners, the replacements I bought are perfect ID for my flex shaft but the OD is about 1mm shy so it moves freely in the brass tubing any thoughts on using this. If I don't use a linger, my brass tubing ID is like 9/32 but my flex cable is only 3/16.... lots of space in there based on the different sizes. Any suggestions or thoughts. I would love to order 5mm (or 3/16) ID teflon with OD of 7mm (9/32) having a heck of a time finding anything online.

Try Kintecracing.com... OSE has virtually no stock, except a bunch of reverse stuff.

I run and race with both....P-Lim system = .150 cable and teflon. Full P or bigger gets .187 flex with no liner. 1/4" brass for both. Just keep 'em lubed!

Thanks for all the answers!

I have a 6mm stuffing tube with 3/16 cable. Gonna use 6mm with no liner i think.

I will put the stuffing tube all the way into the stinger, and then bend it. And glue it off course... So the stuffing tube will sit a lot of cm outside the hull.

What do you use to cut flex cables?

[CraigP]

You should solder the end to be cut, then use a high speed cutting wheel, like a Dremel tool. The soldering keeps the end from unraveling. I assume you are cutting where the cable meets the motor coupling...

I dont have s dremel... what else? 😛

I have a large pair of lineman's pliers, that have a hefty cutting wedge in them. I used that successfully on my first shaft. I then used my table grinder to clean it up.

Kristain, you need a Dremel tool. A very handy thing to have! I have the Drexel 7700 battery powered. I ordered some 1500mAH battery packs as extras.

A Dremel is a "must have" in r/c.

Bought a dremel! Dremel 8100 😊
