Thumbs down Wood dowels in drive shaft.

I went to beef up my drive shafts...
and saw 6mm thread-all being used as well as
similar sized wood dowels.

I found out the hard way that
the wood dowels should be avoided.

Thing is...

If you ever play in/near water...
or the dowels wick up moisture.
It will expand the plastic on the inner drive shaft
and freeze the sliding action of the the inner to outer shaft.

If you never roll near moisture...
you may be ok...
But I wouldn't bet on that.

If using wood dowels to strengthen the inner D shaft...
I would recommend epoxying the end and sealing that off.
Not sure if it could still leak at the other end !?
But I'm not testing that...
and instead will look for some 6mm thread-all.

Hopefully the build up of rust won't cause the same expansion.

Anyone else run into this issue ?

Same here. Drilled and tapped so if I want to remove it I just thread in a m3 bolt and pull it out.

I used carbon arrow shaft and put a bit of shoe goo on to hold it in place. So far lasted a year and a half in my wraith with no problems

You know the axial parts tree is just the right size to fit in the drive shafts right? Almost like ti was meant to be, check it out.

Just cut them long enough to stick out the end when pressed all the way in, for removing them.

Junfac's don't hold up to average power. Mips are the best bet. $40 and you never have to worry about them again.

Nonsense. I have a set of junfacs that are over 2 years old and have held up no problem to a 16t CrawlMaster on 4s. The yolks are still tight. I clean and regrease often.

Thats not power.. I'm talking brushless, and they don't slide well under power, and break off at the yolks
