Arkbird OSD/AP

►Infos
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

Buildlog:
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.
