Re- read my post:
I didn't say the report said the accident was caused by your friends size:
The original query was whether size of pilot mattered in a Cassutt and from the accident report I'd say it was safe to say that the AAIB felt the need to mention cramped cockpits and taped nuts on canopy to prevent helmet damage.
Ergo: if you're 6'3" think hard about whether flying a Cassutt would be a comfortable experience.
Safe flying
