Oh man, great minds do think alike! Now you know why the 3rd safety cover is blank. Nobody would ride with me if it was labeled. The Martin-Baker seat mechanism works fine but I haven’t put any effort into the breakaway roof panel yet, because the cosmetic upgrades were considered a higher priority. If I’m forced to use the seat, the passengers head is going to cause a lot of damage to the cab. Since that level of destruction is beyond my skill set to repair, I’m leaving the switch unlabeled until I get around to addressing this minor shortcoming.
