Where he had trouble getting the bolts through the bottom of the seat. I did the same thing initially and go, "this can't be correct". It wasn't. Contacting Chris at Obutto I learned where they are supposed to go. Note the difference below. It makes a big difference in how much fore and aft movement you have.
Next, it's better to connect the uprights to the monitor than to try and drop the monitor onto the attached poles. FWIW, he put his bolts through the top, mine went through the middle. I'd love to have had them in the bottom holes but that wasn't going to happen with big bertha monitor. Image does not have bolts through the uprights.
He said two hours with phone calls and kids. Okay, that's doable. But I don't see how people can fit their flight and race setups and seat position in that time and really check it out. Maybe he just got it together then plans to change it later. Also, he didn't have the flight sim add-on or the tabletop. I love that tabletop.
He added the foot pedal assembly before doing the steering wheel mount. Ouch. The foot panel is a supplementary piece, and should go on afterwards. Doing it in that order the wheel mount slides up and down fine.
