Introduction
The VTC250 tricopter features a simple tilting rotor design allowing level forward flight. In addition
to the supplied hex keys, you will need a Phillips screw driver during this build. It is recommended
you use blue loctite (or equivalent product) on all screws inserted into metal parts only. Do not
use any thread locking substances on any of the plastic parts.

Pivot Tube Assembly
1. Slide the Alloy Steel Dowel Pin M2x16 onto the
Rod End. Insert the Alloy Steel Dowel Pin M2x16
into the holes on the Tube Clamps as shown.
2. Position the Tube Clamp assembly within the Tube Pivot Block and push the 12mm Tube
through the holes using a twisting motion.
3. Align the holes on the tube with the threaded holes on the clamps and use two Button Head
Cap Screws M2x0.4x18 to secure the tube in place.

4. Make sure the rod ends are pointing towards the center of the base plate and the cutout on
the tubes on the opposite side towards the ends.
Mount the tube assembly onto the Base Plate using four Button Head Socket Cap Screw
M2.5x0.45x8 on the same side as the countersunk holes. Note the orientation of the tube
pivot block with respect to the base plate.
5. Secure the two servos on the Servo Mount Frames using two Socket Head Cap Screw
M2x0.4x6.

6. Mount the Servo Mount Frame onto the
base plate using two Flat Head Phillips
Screw 9mm Length. Do not over tighten
screws.
7. Mount the tail Servo Mount Frame onto
the base plate using two Pan Head
Phillips Screw 9mm Length. Do not
over tighten screws.
8. Assemble the Motor Mount onto the ends of the tubes using a Motor
Mount Clamp and two Socket Head Cap Screw M2.5x0.45x16. Align
the locating pins on the clamp and mount to the guide holes on the tube.
IMPORTANT: Do not completely tighten one screw, then the other.
Tighten each screw a little at a time to avoid putting too much stress on
one side of the tube. Tighten screws just enough to remove any play on
the motor mount.
Note that due to the tube length and frame size, 5 inch props are the
max size that can be used with this frame.
Do not install motors at this time. Simply choose the orientation of the
motor mounts based on the intended motor size you plan to use.
For 1806 18mm diameter motors, install
inside the motor mount. Use supplied
washers with screws to mount the motors.
For a stator diameter larger than 18mm,
rotate the motor mount upside down and
install motors on the bottom side.

9. Using a suitable servo controller, center the servo spline. Push the servo horn onto the spline
and secure in place using the M3 screw supplied with your servo.
10. Slide the Short Push Rod through the Servo
Horn & Linkage Stopper Assembly and
into the rod end as shown.
11. Tighten the set screw on the Rod End.
12. Align the Motor Mount to the Base Plate and tighten the set screw on the linkage stopper.

13. Using a suitable servo controller, center the tail servo spline. Align the flat surface on the
Servo Tube Hub to the Base Plate and push onto the spline. Secure in place using the M3
screw supplied with your servo.
14. Mount the Tail Tube Pivot Block onto the Base Plate using two Button Head Socket Cap
Screw M2.5x0.45x8.
15. Push the 12mm Tail Tube through the hole on the Tail Tube Pivot Block using a twisting
motion. Secure in place using the remaining Button Head Cap Screw M2x0.4x18.

16. Install the Vibration Dampening Rubber Balls and HD Camera Plate onto the Top Plate
noting the location of the countersunk holes. Prepare the FPV Camera Plate at this time as
well.
17. Mount the top plate and FPV camera plate
onto the base plate assembly using the
remaining six Button Head Socket Cap
Screw M2.5x0.45x8.
18. Use two Flat Head Phillips Screw 9mm
Length to secure the servo mount frame
to the top plate. Do not over tighten
screws.
19. Use two Pan Head Phillips Screw 9mm Length to
secure the Tail Servo Mount Frame to the top plate.
Do not over tighten screws.
