Need advice about this stinger with BB

[Alfa Spirit]

Do you know this stinger available CW and CCW, it looks interesting for a mono or a cat (twin)

The stinger, itself, has nothing to do with the prop rotating CW or CCW. CW & CCW rotation is dependant on how the flex shaft is wound, and the direction of the threading on the prop shaft.

Really? Seriiously or this is a joke?

I like the design of this stinger, it's different of powertrims we are used to seeing.

No joke. Go to OSE, or any other site selling struts/singers...do you see them selling any that are specific to CW or CCW? Nope...because they are not rotational direction specific. I might still be somewhat new to RC boats (if you consider 4-5 years as "new")...but, this is an easy fact to figure out, just by checking out any RC boating website.

I thought you were the one joking considering you have been here since 2009 with 2100 post! How can a hollow tube that the shaft spins in be directional? If so, is the brass stuffing tube also directional? Of course not, its just a damn tube with a cable in it no different than the stinger is! Its the wind direction of the flex cable so its doesnt uncoil itself running the opposite direction, and the props that are R/L directional.

I only wanted to say that flex shafts are available in both direction, no more.

If you are running 2 stinger then you need one of each CW and CCW. Make sure you get the right props for the rotation of the flex shafts and put them on the correct flex shaft.

some Stingers are design to be CW and CCW, i have 3 stingers from Arrowshark for gas boats that turns CCW only. The extension on the stinger is left hand treaded so as the shaft turns it will tighten

That has nothing to do with the "stinger" and everything to do with the shaft itself.


I am curious about the ball bearing stingers though. Does anyone know of others with ball bearings? I like that idea regardless of rotation.

Thw old MBP click drives had bearings in them. They needed to be replaced every few seasons. Some of the other high end cat drives from Germany or CCFP also use a combination of bushings and bearings. Can't say that I've seen an off the shelf stinger with bearings. I had some modified to use a stack of bearings held in with a snap ring on my Rivercat and Mini Zonda boats.

I use to do this with my wire drives too but fitting them in a standard dimension stinger was a pain. I ended up with a smaller shaft than I wanted. If your prop is any bit out of balance it beat the crap out of my bearings.
