Raimo,
Have you seen the German registered AN2's?
Because of our "Greens" they have a silencer mounted on the side that looks like
a 200 liter oil drum!! I am sure that it does not affect the wonderful aerodynamics
at all though.
A lot quieter though, inside and out.
I have met a family of campers in one on Endelava. Better that towing a caravan
through Europe.
Have fun.

Subject: | Re: cameras and mounting |
Hi Pete,
The Youtube clip is really clear and steady (no vibration). How is the
camera mounted onto the airframe.
I had real problems with vibration from the airframe.
The only way I managed to iron these out was to mount camera (it's a bullet
camera) on the headset side but only problem is that every time I turn my
head the field of view changes which doesn't make for good viewing.
The camera is a VIO pov camera which in itself is excellent as the camera
and control box are separate - you can see what the lens is seeing in real
time.
Just need to find a way of damping out the vibrations.

Hi John,
I'd be really interested in seeing some of your vids! They would be
inspirational for my build. I'd be happy to pay you for a DVD or two
:-)
Since getting back into the air last November I've also been videoing my
every flight (in a group-owned 1946 Fleet Canuck sadly - but it is
a tailwheel and does have a stick :-) Taking vids started out as a
way for my ailing father to go flying with me vicariously (which he enjoys
immensely), but I also see the value in reviewing my flights and performance
(or lack of it). Here's a short 1080i (one has to select the higher
resolution) example I threw up on youtube from last
winter: http://www.youtube.com/watch?v=ACiM2u0YTvw
I find the GoPro2 to be a great little camera - and even in the noisy/shaky
canuck, the vids come out clear except for some vibration through the
resonance point. I attempted to smooth it out with by adding weight to the
camera with mixed results. I am using the rubber-ball ram mount system
(clamped to a cross bar behind my head) which obviously has some flex due to
the rubber.
I bought a couple of earbud-size mics and velcroed them into my A20 headset
(Did I mention the Canuck is *noisy*?), to get some background engine
noise/music/atc into the vid. I picked them up them from:
http://www.soundprofessionals.com/cgi-bin/gold/item/SP-BMC-2
The GoPro2 also takes great still photos. The resolution from even 1080i
frame grabs is pretty darn good.
Cheers,
Pete

Raimo,
I understand that the AN-2 controls are so heavy that you have to be a Russian
weightlifter to fly it. Heres a picture of an AN-2 I came across at the remote
northern Uganda airfield of Arua in June 2010, on border with South Sudan and
Democratic Republic of Congo. It was used by the Uganda army (UPDF), who had
chartered it from an Israeli operator, for flying supplies to their forward
bases in Congo against rebels. This cargo consisted mostly of bananas and US
military advisers. They kindly let me on board for a photo of the panel (see
attached). Sadly, it crashed six months later (see attached), nobody (11 on board)
was hurt, which says alot about the slow landing speed, all that was left
was the frame and a heap of smoking bananas. I attach a report of the crash
in Russian international press. Apparently the plane had no paperwork of any
kind, Certificate of Airworthiness or anything, so it is amazing it was flown
across Africa to that remote spot.
Have a great time, I am highly envious!
Best Richard
Kenya

Hi Carl,
The Canuck is one very vibrating and noisy fabric and tube airplane (a C-85 with
a currently unbalanced prop), and I was very surprised that the camera image
didn't shake more. It does "swim" a bit in the video if you look closely when
the airframe meets the mount's resonance frequency. Because the aircraft is
tube&rag, mount is a combination of RAM parts:
http://www.gpscity.ca/ram-mount-steel-u-bolt-motorcycle-mount-base-ram-b-231u.html
http://www.gpscity.ca/ram-mount-long-arm-b-socket-ram-b-201u-c.html
http://www.gpscity.ca/ram-mount-camera-mount-mini-plate-rap-b-366u.html
+ the stock GoProHero2 mount.
I noticed that when I made the mount longer with another length and a 'joiner'
the resonant frequency changed as expected. I fabricated a 1 lb steel wieght
and tried it on the camera end of the mount in a hope that the resonant freq would
decrease below idle, but I found i would need much more weight and stopped
using it.
The Hero2 doesn't advertise image stabilization, and when hand-held seems to b
e very jumpy, but on the (vibrating) airframe its pretty good as the vid showed.
Better than expected on my trail-ridden dual sport motorcycle too. The colours
are better than that video depicts, as that was a very grey/dark day here
in springtime Ottawa, Canada.
After reviewing many cameras, the Hero2 came out with the best quality, and I have
been very happy with it.
Cheers,
Pete

We replaced our fuel regulator when trying to figure out why our pressure varied
about +/- .5 psi. The old regulator diaphragm had a funny appearance that the
Rotax tech hadn't seen before. It's a pretty simple device and you can open
it and clean the valve inside.
We do not see a change in fuel pressure when going from idle to 100% power (we
haven't found a need to use 115% power even at high density altitude) and our
EFIS is set to alarm at +/- .5 psi from nominal.
We think Remi is on the right track.

Hi Frans,
A word of caution when running the engine with the TCU inactive: do not overboost
the engine. Let say you turn off the TCU at full power at 4000 ft; then at
a lower altitude the fixed wastegate will allow the engine at full throttle to
produce more than 115% power. I also suggest you reduce power before switching
the TCU back on.
Hope that helps.
Remi
