Note: 150HP O-320
I thought all you builders might like to see some flight test data...above. Its from G-IINI #90360. The TAS are calculated by the method shown at http://www.kilohotel.com/rv8/rvlinks/ssec.html . In summary each run is three runs to work out the wind effect, with data recorded from the GPS.
The prop is a two blade c/s electric MT.
Our flight testing showed that at 74.7% power, 8000feet we were doing 184mph (or
160Knts). Since VANS quote 172mph on 135 hp and 186mph on 160 at 75% I feel
G-IINI is performing as advertised.
Keep riveting, Steve.
#90360, G-IINI
PS Gus my performance issues are all about ASI errors which I have not yet sorted.
I am very suspicious of the drain holes in the Dynon pitot head.

My quickbuild fuselage and wings have arrived, I need a rough idea as to the amount
of working hours until the wings are final attached so I can sort out timing
for hangar rental. Any suggestions welcome
Thanks
