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?).
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.
Twinstar FPV: Huyck-Field from Mario Schimanko on Vimeo. If you look close you can see the oakmountain-field (behind the castle) and down the city you see the big white building again (chockolate factory with my airfield behind).
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.
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?
