xtra long driveshaft ok?

[mpatrick]

I am mocking up a custom TRX4 that will require a ~180mm rear driveshaft. Ebay has some solutions that fit my length need, but ultimately I am worried about vibration or whatever.

Any thoughts or wisdom on this subject.

I have the stock Hauler carrier that could be used if needed but I would like to avoid it due to link length and space constraints (assuming it will fit).

I have a pair of skid-forward builds running 160mm+ cheapo Amazon driveshafts (FriHobby) with no issues. If you're worried, you can always go with the cut-to-length from Dlux, which can be had up to 210mm. https://dluxfab.com/Dlux-Cut-to-Leng...aft-p415417072

I've glued together several Wild Boar shafts to make a long one in my Crawler Yeti. Works fine so far.

Speed is the key point here, if your rig is doing normal crawling speeds (< 10 mph), then you'll be fine.

Thanks for the great ideas.

Cutting and glueing stock style shafts is my first (and cheapest) plan as I have extras laying around.

For sure, if I had a high speed yeti, I'm sure balance would come into play. Since it's a slow crawler, it works well.
