I guess that's what happens when you have a relatively slow stall speed, she starts flying in a lot less wind 
Any takers on my chemtrails photo? The answer to the location is in the detail.... There's really only one place in Australia that this photo could have been taken (from a capital city perspective).

Canberra XXX?
Guessing that's the SYD-MEL route?

Yeah not bad Morno. Must make the Canberrarians feel left out to see that. Brilliant weather in Canberra this week (apart from the afteroon tropical storms), you wouldn't see a formation like that otherwise.

On the pic of the airvan, how do they get it back the right way up without causing damage? It doesn't look straightforward to a simple sailor,like me..
Don't tell me it just takes a couple of strong Aussies

Yeah I'm guessing the damage has already been done. That wing strut might tell a bit of the story.

I refer to a V35TC Owners Manual at hand dated May 1967 which notes a two bladed propeller. A read discloses no mention of three blades as standard or optional but does say at 8-11, Propeller blades: "The daily preflight inspection should include a careful examination of the propeller blades for nicks and scratches. "EACH" blade leading edge should receive particular attention". (my emphasis).
The three view at iv shows a two blade propeller with 7' 0" diameter.
I have a few hours in V35TC VH DLO back in 1974 which had a three blade propeller, (from memory), and was told it was for ground clearance, didn't make any difference to performance or weight. I don't know how accurate this advice was.

Clinton,
CFS = Civil Flying Services
All four CFS Bonanzas I flew in the period 1966-1970 had three-bladed props; CFB (an S35), CFC, CFH & CFK (V35's). An oddity, since the 8 Barons (an A55, B55's & C55's) there then all had 2-bladed props!
There also was CFV (another V35) lurking around at Moorabbin, but I never even saw this one nor can I locate any photos.
S35 VH-CFB at Parafield in 1965, before the blue airframe/yellow tail madness took hold..
V35 VH-CFH at Warracknabeal in 1967; not me flying but I was married to the lady in the RH seat for many years!
V35 VH-CFC at Jandakot, 1969.
They're all Geoff Goodall photos, btw.

Clinton,
I've heard this sort of story before, i.e. aircraft with two bladed props are faster than identical aircraft with three bladed props, although I have no expertise in this area. Mind you, I could waffle on about Chipmunk props ad nauseum!

I find it hard to believe that a properly balanced 2-blade prop will be smoother than a properly balanced 3-blader!
While I did not fly my V35B when it had a 2-blade prop, I understand that it was a couple of knots faster than with the current Super-scimitar 3-blade, however, it apparently climbs way better with the 3-blade.
My V35B with the Super-scimitar prop outclimbs any other normally-aspirated 285 hp IO520 engined aeroplane I have flown, with similar load. With full fuel (285 L) and three up, it will consistently make A100 in 10 min.
My best climb to-date is FL180 in 30min/55nm!

Whether it's true or not (but does make sense to me) is that a 2blader will generally be smoother on a 4cylinder and a 3blader better on a 6cylinder.
The practical theory being that the each blade will be in the same place during the same part of the firing cycle, hence smoother operations respectively.
Speed however, will be more of a function of power provided by area/lifting properties of the blades, irrespective of how many individual blades the prop unit comprises (think of the difference between a 'cruise' vs 'climb' prop on a fixed pitch setup.

Owned a 310L once with 2 bladed props Was quicker than a 3 bladed Q but used to get this shudder from front to rear every few minutes in smooth conditions when the props used to get out of phase not sync as it was explained to me. Quite unnerving until you got used to it
