flex saver

[video200]

anyone know were i can get a hold of "flex savers" for 150 flex ?
lost 2 shafts and 2 props in less then 2 weeks now

3/16" wheel collars....any hobby shop

tnx sailr. sending inqueries to the norwegian shops now hoping they have inches and not only mm :)

4mm should be close enough for .150 flex. .15" = 3.81mm

Having .19mm runout on a collar attached to your flex seems like a good way to ensure that it will break, now your just gambling which side of the collar it fails.

there have to be something that just fits and dont create the exstra vibration so it breake.
have atleast learnt that next time i wont build with a stinger but go for a strutt\ferule instead. then the flex can breake but the prop and shaft is still there.

Why not installing a "propsaver" behind the centre of your prop ?

becose i lost the flex and everything with it.
first time it came out of the collet ( sinse i forgot to solder the tip of the flex i suspect) and yesterday it did the same for some reason. collet is new. flex was solderd. was room for the flex to compress when running. only perk is that this happend a few feet from land so i wil to get the prop and flex back with a little luck

With the propsaver as shown you can't loose anything !

Idea, the wire bent behind the prop can also be a cooling tube!

[Gerwin Brommer]

If you wanna do THAT, use a wire AND a tube connected together.
A tube alone isn't strong enough in case of breaking a shaft/flex.
It would bent backwards and oops, prop/shaft are gone :-)
And : a coolingtube at the centre of the prop : where no water is.......

wil have a look at wjat kinda wires we have at work a 2mm wire shold be able to hold a prop back from sliding if the flex breakes.
tnx guys :)

I have 3 boats with cooling tubes behind props just below the center and there is LOT's of water coming out

[Gerwin Brommer]

yep, like you said : just BELOW............ ;-)
