Looks good on paper, but it's not just Lightwings.
The reality is, 3500 assorted aircraft from 220 various types, each with at least one, maybe two option choices for mods, updates, etc.
As for factories, a third of the aircraft above no longer have manufacturer support, hence the reason to legitimise repairs, mods, etc via a central authority.
I have had a response from Darren showing interest in my proposal, but as you can imagine, this is like opening Pandora's Box, so Barren will be flat out for a while 'till this is under control.
His response included getting talks started between Bolly and Rotax, re some form of bulk approvals.
I did receive some paperwork from Warp Drive last year describing their work towards (self?) certification, to comply with supplying props to the LSA manufacturers.
This paperwork was forwarded to Darren, but it may need an initiative by Wade(?) or whoever now supplies Warps, for a similar bulk approvals.
No noises regarding costs yet, but then it is a bit like asking 'How long is a piece of string?'
