Did no one notice that the original post came from Australia?
After a few years of thorough responsible study, CASA, the authority there, allowed kit planes full IFR/night flying, provided they met specified, reasonable criteria, which if I remember correctly, included certified engine, prop, instruments, and a professional survey of the electrical system.
O that CASA could take over our CAA!
Also allowed by several other countries, including US, Canada, Sweden.
No such country has had reason to review its decision.
On Bose's comment on plastic hot ships, remember these cover a huge range of capabilities. My little one will carry two 14st people, 50lbs baggage, 6 hours fuel, all within approved W&B. And gets to Barcelona non stop from here in less than 4 hours, loads of fuel reserve.
Back to the CAA, and the CT2K question. The a/c has been replaced by the CTSW, which was designed, and now certified, for the 600kg US sports utility category. Exactly the same aircraft is limited to 450kg microlight category by the CAA, and therefore suffers as Bose says.
