I'll post in this discussion line as it's not worth starting a new one. That said, it may be of pleasure/interest to you Jabiru-ites out there.
I'm a non-pilot "enthusiast" (I like to watch, as the voyeur put it...) but have been lucky enough to have had flights in such things as Tiger Moths (with a barrel roll on one occasion!), Austers, Stearman DH Beaver and Chipmunk. Lots and lots of fun, as you might well imagine - and I really count myself fortunate to have had such treats.
Now Jabirus I have hitherto regarded as a sort of plastic streamlined tadpole modern "thing" of no great virtue. Somewhere I had picked up the belief that their rate of climb depended, like the fully laden B-24, on the curvature of the Earth.
Well how bleeding wrong was I !
A couple of weeks ago I got to fly in a 6 cylinder Jab: and simply could not believe it! Takeoff - vroom! Climb - zoom! Chuckability - whee!
As well as all this, the damn thing was smooth, sophisticated and civilised. Fan-bleeding tastic.
Looking behind, I see a cavernous space for the other two passengers/baggage: what a useful unit!
In short, I've been converted: while I just love the nostalgic vintage aircraft experience, it's obvious, like the canine dangly bits, that there has been a very great deal gained in the last 50 years or so.
As a post script, in the interests of exhaust valve temps the owner/builder runs his engine a little richer than normal - at a small increase in fuel burn - and at (?)hour intervals he changes out the exhaust valves; their price isn't prohibitive so for him it's a case of safety at a reasonable price.
Happy flying, Jab-ites! [ATTACH=full]1745[/ATTACH]
