I did buy a pair of Servostiks + Mechanical Rotary Kits some weeks ago as a replacement of my Happ Rotaries.
They work great and are totally worth it, BUT I had to make some tweaks and modifications to make them feel right:
- The spring feels too loose for my taste in comparison to an american stick (put a nylon washer between the spring and the base to make it a bit stiffer).
- The microswitches are way too clicky and hard, making contact only at the end of the actuator's travel. The reason behind this choice is to avoid hitting diagonals in 4 way mode before the actuator reaches the restrictor plate, but playing any fast-paced games (i.e. schmups) with this configuration is very frustrating.
I fixed this, replacing them with cherry microswitches and bending the switch actuator just a little bit for a longer travel (but not as long as the other ones)
The rotary kit is not too dificult to install but I had to cover the lower part of the handle with a piece of heat shrink tube, cause there was no way to fix the handle to the collar just with the screw (at least for me).
Keep also in mind that the kit is ONLY for the Ball-top version, not for the Bat-top. The replacement handle is smaller in diameter. Andy has updated this information recently on his web page as soon as I pointed him out about the smaller handle, but I already received my Joysticks and had therefore to buy later a pair of suitable handles.
After the above mentioned tweaks they feel far better than my old Happs-rotaries.
