Basic Theory
Foxtech AYK-250 is a long-endurance tail-pushed VTOL with high efficiency specifically designed
for long-range inspection, surveillance and mapping jobs, which can realize 3.5H endurance with
1.2kg payload.
Foxtech AYK-250 adopts carbon fiber integrated molding process, which makes the whole body light
and durable, the aerodynamic design and smooth surface ensure a low air resistance.
The quick-detach design on both fuselage and cable connector makes it easy to assembly the drone
in a short time. In particular, the detachable tail design has the advantages of reducing the volume
and convenient transportation. The detachable payload compartment is also convenient for loading
different task equipment.
With long duration and stable flight performance AYK-250 VTOL can be applied in inspection and
surveillance,mapping and survey by loading different gimbal cameras or mapping cameras, such
as Foxtech 10x/30x zoom cameras, 3DM-V3, Argus V2 oblique camera and MS600 multispectral
camera etc.
In mapping combo AYK-250 VTOL is equipped with Foxtech MS600 multispectral
camera and DA16S+ radio controller featuring 8km rc/data transmission range, which can be used
for crop condition and water quality monitoring, resource investigation etc.
AYK-250 VTOL equipped with SEEKER-30 TR 30X zoom camera and T30S dual-screen ground
control station featuring 15km rc/data/video transmission range can be used for long range
inspection like public security, border defense and energy industries.

Although the accelerometer was calibrated already for the PNP version before shipping, please
calibrate it again since it might be affected in the transportation.
Under Initial Setup, select Accel Calibration from the left-side menu. Mission Planner will prompt
you to place the vehicle each calibration position. Press any key to indicate that the autopilot is in
position and then proceed to the next orientation.
The calibration positions are: level, on right side, left side, nose down, nose up and on its back.
1..Calibrate the Accelerometer
Click this button to begin accelerometer
calibration.
This accelerometer trim can be used
to level the HUD horizon.
11.t is important that the vehicle is kept still immediately after pressing the key for each step.
2.The level position is the most important to get right as this will be the attitude that your
controller considers level while flying.

Onboard calibration produces better results.
2. Compass Calibration
AYK-250 VTOL uses high sensitivity compass and it has to be re-calibrated when fly in a new place.
Enter the compass setting page and click”start” , hold the plane and rotate it in order to hit all
directions on a sphere to calibrate the compass, when it’s done, a new offset would be given to the
flight controller, and a reboot is necessary.
3. Radio Control Calibration
Calibrating each of the transmitter controls/channels is a straightforward process - simply move
each of the enabled sticks/switches through their full range and record the maximum and minimum
positions.
