Construction Photo Notes.

#4dpa

After Note:

Fly well. Need good construction (no twist between both side of the wing) and test fly. Perfect hobby DIY project with MQ-1A Predator

If roll, adjust main wing to count balance.  check Function of aileron (Fig.2)

If pitch, adjust tail wing for up or done. No adjust weight is needed when following construction.

Each adjust at wing should be very minor (0.5-1 degree of change at tip of the wing),
