Arkbird OSD and Autopilot on the new FPV Plane "XUav ONE"

See this nice plane in my hangar, a few build tips and closeups. Find lots of infos in description!
X-AUV One plane
Arkbird OSD/AP

Buildlog from the MFM Material version with some good tips
another Buildlog from SchumiXD of the EPO Version (the same as what I'm testing)
useful RCGruops Thread

hotglue the servos
glued vtail foam into plastic parts and carbon rod with hotglue
screw on the V-tail fins (secure servoconnectors with tape inside the tail-boom!)
mounted the 3536 1800kv turnigy motor (was easy fit there)
add grease into gearbox (crane grease)
used 60amp Turnigy plush ESC - plenty of space - ESC cables routed outside through air flow
add linkage to servoarms
currently use 5channels directly on radio, later add autopilot

first tries with fixed styrofoam nose - later installing FPV cam on 2axis gimbal (to look around)
(roll axis? to stabilized image - but this is useless with servos - one would need a brusless gimbal - so roll servo is useless IMHO)

CG: to achieve proper CG (around 75mm from LE) I had to move the battery (5200mah 4cell 433gr) all the way forward, did even carve out some more foam from the nose itself - so battery sticks a few cm in the nose). Also added some dead weight directly in the nose ~ 100gr) and the Runcam2 ontop the nose.

Runcam Owl Plus Review (compared to HS1177, night vision comparison - how dark?)

Runcam sent me their top cam - let's see if you can fly in total darkness with it! I compare the Owl against the popular HS1177 with a nice dual monitor setup.

►RunCam Owl Plus Specs:
1/2″ image sensor
700TVL horizontal resolution;
150 degree FOV lens (2.4 mm)
5V to 22V (suitable for 2s – 5s LI-POs)
light senility, 0.0001 Lux/1.2F min. illumination
Digital Wide Dynamic Range (D-WDR)
Digital Noise Reduction (2DNR)
Automatic gain control (AGC)
Back light compensation (BLC)
OSD menu
26 mm x 26 mm x 30 mm, 15 g net weight.

The OSD is pretty straight forward, just activated the DWDR and played with colors and contrast a bit.
Not as good with shadowd vs. sunlight on the day, but awesome in the night. Although you shouldnt expect to fly a miniquad in acro mode without "some" light in the night.
If you use it on a GPS stabilized quad or plane you could really almost fly in pitch black nights.
If you wanna explore darker buildings you will be surprised how long you get coloured images until it finally switches to BW mode.

I will have to do a few flights, but I think you can definitly use it as a standard cam and also fly in daylight if you are not too picky. And it is definitly better than those cheaper CMOS cams (like the one that came with my Vortex250).

ProxSCHIMity - fast and low through awesome scenery, treesurfing

The kind of flying that I love the most. Gives you the "flying like a bird" feeling the best if you fly close over/under the trees. Found an awesome new spot with a huge field enclosed with some nice trees and a forrest surrounding it. Also flew on my "Eichberg" a lot and found some new lines there as well.

So flieg ich am liebsten, "wie ein Vogel" knapp über Bäume oder darunter durch wenn Platz ist...
Hab in der Nähe ein tolles Feld gefunden, welches perfekt ist für diese Art des Fliegens. Hoffe es gefällt Euch!

Quanum Cyclops Goggles - best value for money goggles! |RCSchim Review and Fieldtest

Pricetag only 53€ / 58$ - get them here
See this review if you wanna start FPV and search easy to use goggles. Pricetag is really beginnerfriendly as well!

HK sent me these really cheap and easy goggles for review. They are clearly aimed for the FPV starters. You dont have to know much about video downlink the get decent image on the huge 5" display which is set in the right distance / size with the fresnel lens.
Just press the autoscan button and it chooses the channel on which your FPV vehicle transmits.
What to do if you want to view a specific channel - let's say on a dronerace where you wanna spectate? I dont know, sorry :-)
No info in the display about the channel / Band you use either.

They are only a bit more expensive than the Quanum V2pros - but the Cyclops comes with an integrated VRX!
But attention! NO AV in - so you cant use groundstation on cyclops!

My GF liked wearing those more than the DominatorHD (easier to get used to for casual users!)
I still prefer to use my DomHDs of course - but I could fly with the Cyclops without much getting used to. I had my problems focussing on the V2pros - the Cyclops looks and feels definitly better!

Lens adjustable (though a friend with glasses couldnt get it sharp for him), really comfortable to wear with the foam!

5" 800x480 display (with option for 4:3 aspect!)
Operating Voltage: 7.4 -12.6v
Receiver: -90 dbm ISM 5.8GHz 40ch
Antenna connections: SMA
Operating Current: 600mA
Dimensions: 187(L) x 179(W) x 121(H)mm
Weight: 390grams without batteries (they feel lightweight!)
nice set up power adapters (XT60, 9v Batteryblock

40 channels A, B, E, F and Racing bands

Vortex 250 - natural racer - una festa sui prati!

Hier hab ich einen wirklich tollen Platz gefunden (neuer Spot auf dem "Hügel" wo ich schon sehr oft geflogen bin). War einfach eine tolle Flugsesson nach der Arbeit. Der Übergang von Blätterlosen Bäumen zu frühsommerlichem "Vollgrün" der Landschaft ist beeindruckend find ich!
Ja und zuletzt hab ich gemerkt, dass mich droneracing auf Kursen gegen die Uhr (oder andere Racer) nicht so interessiert wie einfach einem natürlichen (imaginären) Kurs in so schöner Natur zu folgen :)
Das Lied wollte ich auch schon lange mal verwenden - jetzt hat's endlich gepasst!

This session was only a few days ago. It was so great to fly there I had to share it asap. Been flying on this hill (Eichberg) hundrets of times - but flew on this slope with lush greens for the first time. Flew there a few days after trying to fly on a race. Found out that I'm not the 2min race guy. I prefer to find "natural race tracks" with cool obstacles to fly thru...
Had this song in mind now for a while and think it works nice here (it's italian and means - a party on the lawns).

Vortex 250 | ▶▶Dog and Gliders◀◀ (ext. shots, man walk dog with his RC plane, playing with gliders)

Diesmal gibts schöne, externe Aufnahmen vom schnellen Vortex250, und den neuen Flugplatz bei einem Freund (der seinen Hund mittels RC Segler gassi führt).
Im 2ten Teil gibts mehr Luft-Luft Aufnahmen von meinen Flügen mit den Seglern am Eichberg.

Es wird noch ein 2tes, ähnliches Video mit viel mehr Material vom Vortex geben (Vögel und Warbirds verfolgen, Abstürze und Sturzflüge).

You see nice external shots of the Vortex, and the new flightfield where I fly with an RC friend who uses his RC glider to "walk" his dog.
2nd Part is a longer cut / collection of the magic glider air to air shots I had on the Eichberg.

I will upload a 2nd video of that kind soon with many more Vortex impressions, chasing birds, warbirds and DIVES.
