This time I had to find a way to mount the IF OSC flightcam and the Lumix fx35 for recording HD. First I thought about an safebox with foam for protection and vibration dampening but then I came to this design:
Here I tried out my custom landing gear. It weights about 150g wich can be a CoG issue. If mounted too far in the forward section - noose-heavy flight; too far backwards and you'll see yourself rubbing your plane's nose in the grass :-)
A thrid wheel would be a possible solution - but that also means additional weight. To small would make a hook of it...
For takeoff it helped giving some extra elevator; takeoff distance is quite short for grass (5-7m?).
My conclusion: nice optics, cool feeling on the start, diffcult landings (material consuming), not safe for FPV so far - no extra benefit - I'll stay without wheels for FPV.
PS: did you recognize the music? It's from this Spencer/Hill movie "Plane cracy" / "Zwei Himmelhunde auf dem Weg zur Hölle"
This were a few great rounds above my hometown - above the company I work in to be exact. I did two flights but on one the jaytech stopped recording (no guess why) - so only one landing.

Yesterday I had to FPV a few rounds over the "oakmountain" - the light was fantastic. This time you'll see footage from the JayModCam again, unfortunatly it was pointed up a bit to high...

The mic was covered with foam this time (to prevent heavy noise) - so the air-speed-sound gives you an impression of the actual flyingspeed and motor usage.
I scaled to 640x360 to have smooth vid with 30fps (the old story). I'm still not satisfied with the tele of the jaytech - wide-angle would make a much better overview.
This was my third real FPV flight - and it was great. Great conditions (only a bit foggy), no technical problems, huge airfield with plenty of space to land...
Next I'm planning to go back to my JayModCam for recording - should give better quality (now I use a USB Framegrabber wich interlaces to vid - this makes it worse). Video-Downlink quality is great for flying altough!
First of all - this vid has no real landing - rather a crash. I was lucky enough and my twinstar with its brand new cameramount was not damaged. I'm not really sure what happend - easiest explanation would be a bad piloting, a stall during the too hard and too low turn. It could also be that one of the motors had a failure - this wouldn't be that great. After the crash I could successfully test the plane. Second problem (which is also visible): the cam settings have to be improved. Maybe it's because of me using only 8,4v instead of the recommended 10-12v. I'll check this first.
Update: now I tried 12v (a small Kokam 3cell 310mah lipo) and the cam works fine - so don't use less than 10v - quality and automatic lighting will suffer from low voltage! So this was no real FPV flying because you can see that the sunlight could really bother you with this settings. - Please choose your own music - I was too lazy :-) Btw. the oakmountain is named "Eichberg" in german.
The cammount hast been bent back and than I tape-wrapped the two supports. Perspective from there is great, but the ultra-wide angle is weird for FPV flying - I'll sty by the "normal" wideangle.
Now that I have a new, working FPV cam I made a new cameramount for it. Combined with a wide angle lense it will give me a cool perspective (video should hopefully follow shortly!): I'm not sure how the "cameramount" will affect the aerodynamics - any comments?
