Emax MT1806 allen wrench size

[liamcostello]

Hi all. I am a newbie to this Forum, but certainly not to this earth! Name is Bill. Question: what is the size of the allen wrench (or bolts) and where can I get a long one like that used in the video? Thanks much for help.

Can you link to the video you referenced? Great to meet another fellow earthling.
