Step 9
Finding the Vapor’s Center of Gravity
The Vapor’s front wing mount should be positioned at approximately
28–30mm behind the front of the fuselage for the initial flights, with
the front of the battery tray positioned at approximately 10–12mm
behind the front wing mount. The Vapor will fly at a wide range of CG
positions, allowing you to alter the flying characteristics of the
aircraft. You may also experiment and add a little “up” trim to the
elevator which will bring the nose up slightly in flight. This will provide
the airplane with the ability to fly even slower.
Hand Launching the Vapor
1. Make certain that the aircraft battery is fully charged.
2. Turn on the transmitter.
3. Plug in the aircraft battery.
4. Test the motor and surface controls.
5. While holding the transmitter in one hand, push the throttle stick
to half throttle (up) with thumb.
6. Launch using light force. Keep the wings level. Do not throw it up
or down. Point it level (parallel) with the ground when releasing.
Use caution when launching the Vapor as to not grasp the
pushrods. Grasping the pushrods may result in damage
to the servos.
Step 10
Runway Takeoff
1. Prior to attempting a runway takeoff, you should have had
several successful flights of hand launching the Vapor.
2. Make certain the aircraft battery is fully charged.
3. Turn on the transmitter.
4. Plug in the aircraft battery.
5. Stand behind the Vapor. Make certain you are on a smooth
surface such as concrete or wood.
6. Apply full throttle and adjust controls to keep your Vapor on its
intended path.
7. If the battery is fully charged, you should be able to lift off
the ground in a few feet. As you notice the back of the plane
beginning to lift a bit off the ground, apply some “up” elevator.
Do not give too much “up” elevator, or you can cause the
airplane to enter into a stall.
