i understand. the only issue will be then, I can't register it legally, and i don't have a country house where it can be flown unatended. also, if i would sell it in the future, there can be problem with that too.
better to try the proper way, via EAA, but my local chapter has always dissliked choppers due to many reasons (some mentioned), but som others:
"we have taken in 4 other choppers brand and they all crashed, 100% accident rate". this was like "scorpion 1" homemade blueprints models from the -70, but my eaa still consider all choppers dangerous after that. specially uggly looking bastards with rotating wings. according to them, only fixed wing with 4-stroke engines is good enough.
it is a pitty, since "my" eaa was the 1'st one outside us, they where really inovative in the end of the -60 when it all started.
must mention other issues with eaa:
"will propably not pass noise test"
"high reported accident rate"
"no proper firewall"
"we don't have competence for choppers within eaa"
"service/pilot book is a joke" (one guy that built a safari, wrote his own book - and that was no issue)
on top of that, i was going to take a certificate, build the m5 meanwhile, they said: if you don't have a certificate, we will not approve building permission since you don't understand aircrafts. however, there is no specific rule building without license, but we will not approve it anyway. also, we require at least 100 hours experience.
warm and welcomming nice people at my local chapter indeed!
