"Off-the-shelf" standard Henrys club handles bodies and caps will not work on flowtoys clubs. Henrys makes custom versions of their parts specifically for flowtoys clubs with our specified light transmission and weight, and these are further modified by flowtoys to fit the vision clubs.
Henrys club knobs WILL work for vision clubs, but ONLY use the screws that come with the vision club knobs! We use
# 8 X 3/4 18-8 Stainless Flat Head Phillip Tapping Screws Type A and offer them on our site here: https://flowtoys.com/club-knob-screw
Any other screw many be too long and screw into the circuit board causing physical damage - see picture below. Yep someone tried and this is what happened to their club. This would NOT be a free replacement (it will be a half price warranty replacement).
We do offer almost all club parts separately for about $5/part. You can find handles, knobs, bodies, caps and more club part here.
