Default 2m indoor ultralight depron scratchbuilt Boeing 777-200

Happy new year to all!

I would like to share the video of the maiden flight of my scratchbult depron Boeing 777-200 airliner that flew for the fist time on wednesday.
The build is based on 3w drawings from Boeing, and paper model plans from paper-replica.com all converted and adjusted to my model.
Wingspan is 2m and the fuse is about 2,2m long. Flying weight is 540 grams.
It is powerd by two Emax 1106, 4500Kv spinning 33,5x2x3 HQ Props on 3S 550mAh.

Great job on the build. Amazing what can be done with lightweight materials. It looks like you got it just right on the first try.

That is a great place to fly an airplane like that. You are fortunate to be able to use it for flying.

The build was actually quite straight forward after I solved thechallenge it is to split 3mm depron in two thinner sheets... I used my foam cutting hot bow on a flat surface with 1mm guides on the sides. I also had a long debate with myself and different CG calculators before I decided on the sweetspot where I have it now :-)
As for the venue, my clu bas an annual X-mas/New year fly-in event here, so it was perfect place to maiden it. I had 5 flights and with differentil thrust activated it turns much better, and it will be capable of flyig in smaler venues... btw, our club pays about 800 USD for the 4 hour long event - totally worth it!
