Hello guruguys,
I've seen only one time a brand new dome on ebay, I planned to get it as spare, but I finally gave up... too much shipping cost, and at the end... my 'dome' is not cracked, so why spending money for spare after all
You should contact Alpha1 on this board, he has not so long time ago THREE Starblade, he may have spare parts...
Regarding the seat who doesn't vibrate, there is a wire with connector under the seat... and it's maybe unplugged? I also unplugged mine because the vibration was too strong! (...or maybe I'm too old
).
Do you have picture of the cabinet to show us?
