Gather all the info you can about components and then choose what works. The leathers I was wearing that fateful day were at least one size too large for me. Did they contribute? Possibly. I found the answer on the first day out after my rebuild as I was wearing the same leathers. On the front straight, at speed, they would flap. This shook my body, which shook my head, which shook my eyes creating temporary blindness. Did I pull in and try to fix them? No, I kept going so I could collect those valuable “track day points!” Insanity! Suffice it to say that was the last day for those flapping skins. I spent the better part of a day at Revzilla getting fitted for a set that feel like a part of me. Oh and while there I discovered that I’m not a large Arai, I wear a medium, control surfaces! Your body, what you wear and how it fits all have the potential to change the attitude of your aircraft. For Pete’s sake, get it right!
