The VKAR Bison V2 is serious fun, and about half the price of the Helion it's based on. Only trouble is the weak wishbone connection: the bushing and pin. I broke both of mine and then two threaded rod replacements. Time to create a 3D printed alternative in Onshape. Sliced in Simplify3D and printed on a Prusa i3 MK3, these turned out perfectly. Yet to have a breakage since fitting them, plus fitment and change are much easier now.
