Hi.
I would like to use your 12mm protruded tube for a multicopter motor arm but would like to end up with a square end to hinge the arm.
Looking at your sizes it would seem the best way to achieve this is :-
12mm (OD) protruded tube inside 12.5mm (ID) wrapped tube inside 20mm carbon box.

I already have your 12mm protruded tube and it measures 12.3mm which may be a problem if the the 12.5mm ID wrapped tube is smaller than advertised.

Could you please check the fit before I order. They will be glued together with epoxy.

Thanks

Vince

HI,

I've just been out into the warehouse and the 12mm od pultruded tube slides into the 12.5mm ID Roll Wrapped tube fine.  Likewise tube to box section.
