Ok first flight... not a success at all...
Not even one second in the air and one arm broke, Backpart didnt lift off at all.

Most Probably the Rear Arms where not aligned properly, at least they were not after the crash.

But also some good news: The total weight without Video Equipment is "only" 825g so I'm under my target weight of 900g

P.S.: THAT THING MAKES HELL OF A NOISE!!! I will need some noice canceling headphones I guess  :-X

Yepp, I saw it and I was almost sure there must be something wrong, either motor direction or props.
Thanks for the hint!

I did check that before I mounted the props so the direction is correct but for sure the props are mounted in the wrong way as you can see in the pictures.

The new GPS arrived yeeeey.
The good news: the measurements of the board are quite small with 30x30mm but unfortunately the antenna or whatever that part it is is quite fat. Total height of the board is 10mm. I will try to fit the GPS Antenna (that big beige part) into the Front Top so I only have the board right unter the top. The Antenna is 6mm on height so should fit

Great, would like to see some vids/pics from yours also.

I just connected the GPS and Magnometer to the board and both are enabled and seem to work in iNAV yeeeeey.
I will put everything together and probably start second test flight later.

Just a small... I fixed the broken arm, put everything back together, calibrated the compass and did a small test. So far looks good but I need to wait for the printer to finish printing the new top part with the hole for the GPS.

My plan is to get out after lunch and give it a test flight. Hopefully I will have a video as well.

So second try today... same disaster then last time. At least I was some cm in the air before it turned on the back and this time both front arm broke.
Most probably the propeller broke because I hat to drill them to 6mm and there was only a little bit of plastic around the shaft remaining so I already ordered some simple props that fit my motors for further test.

But as always some good news: The GPS seems so work great. I catched 17 to 18 Satellites under perfect conditions.

New props should arrive on thueday, the arms I will put to print now.

Short update on this: IT IS FLYING!!!

After some mistakes from my side (never fly indoor!!!) I finally got it flying outside yesterday and I have to admit I have a huge respect of that thing!
Im completely new to RC (except a small helicopter for indoor flights) and the drone seems to be out of controll when I fly it but I think I just need some more practice and probably to recalibrate the sensors.

Summary of the first flight:
- it appears to be very fast
- its very agile what I didnt expect
- I can definetly replace the motors with the smaller 920KV Motors as mentioned in the first thread
- I seem to have a sensor problem. After I turned POSHOLD+ALTHOLD on, it stayed for about a second in place and then rolled to the right without stopping so I have to check the calibration again. Could be also because of the wind as it was quite stormy yesterday.
