Mike,
Thanks I'm reading your comments to Bob on the RV 4 and see how it's done now. Great discussion.
OK - by removing the seat, harness, controls etc it then is basic storage behind. My guess is that's round 25 kg reduction in component weight along with the 75kg average for the passenger, it falls well under at around 580 kg.
As I said I'm considering the RV 4 as a quick option that can be flown by any Rec Aus RAA only pilot. The Rec Aus RAA liability insurance as a Rec Aus. RAA member us a huge plus also.
:cheezy grin:Mmmm - then if the MTOW for Rec Aus. RAA does increase it could be re configured with all two seat
I'll keep an eye out Bob - RetiredRacer - for that RV 4 on the RAA - Rec Aus register in Melbourne.
Someone may chime in here with other RV 4 on Rec Aus. RAA
Thanks again guys for keeping the discussion going, its a good insight into options.
