The ability to fly the InView and / or the VuFab unmanned aircraft in manual mode is important:

• should an emergency arise in which you need to use this flight mode

• should you wish to get a feel for the flight characteristics of the unmanned aircarft

• should you wish to get the flight control software to learn from an expert aircraft flyer

There are three steps in unmanned aircraft initial flight training.

In our opinion, the Real Flight flight simulator is a fun, easy-to-use, and relatively inexpensive flight simulator. It does have its limitations: the flight physics is an approximation to the actual flight dynamics. However, it is a good first step.

The current version of the Real Flight flight simulator is Version 5.5.

The Ultra Stik is a lightweight sixty six inch wingspan airframe using an electric motor powered by a 22.2V 5.4 AmpHour Lithium Polymer 6S battery pack. The dual flaps enable a very quick take off within three feet and a precision landing. These flaps can slow the aircraft to such a degree it can almost hover in the air.

Flight time is about 25 minutes with a 22.2 V 5.4 AmpHour "6S" LiPo battery pack.

Wingspan = 1.676 m

Weight = 2.7 kg to 3.2 kg

The Ultra Stik is easy to prepare since it uses a battery powered electric motor, rather than a fuel powered engine. This does mean shorter flight times, but that is fine for an introduction to the manual control of an Unmanned Aircraft.

Above: the 10 channel Futaba Radio Control transmitter is used with the Ultra Stik, the Telemaster Senior, the VuFab Unmanned Aircraft and the InView Unmanned Aircraft. Although the Futaba T10CAP transmitter is shown, the latest Futaba 10 channel transmitter is shipped with the Ultra Stik.

Included in the Ultra Stik Radio Control training aircraft package is:

• A fully assembled Ultra Stik "Ready to Fly" aircraft together with an Operator Manual.

• A Futaba T10CAP transmitter operating at 2.4 GHz together with the Instruction Manual.

• One year of technical support.

The Telemaster Senior is a Radio Control training aircraft fitted with a Canon G10 mid-size digital camera.

The Telemaster is a 92” wingspan aircraft is built out of balsa with lightweight covering. This configuration is stable in any flight condition due to its dihedral wing. Several changes have been made to the standard configuration:

• servo pushrods have been relocated to allow the Canon G10 camera to be used for aerial photography
• a Canon G10 digital camera has been added
• a large capacity gasoline fuel tank is used to provide about one hour and 45 minutes of flight time
• more secure wing fixing assembly has been introduced
• a section has been added to the front above the servo tray for reduced air resisistance
• the aircraft is spray painted matt grey

This aircraft has been fitted with a 20cc four stroke gasoline (petrol) engine for long flight endurance and efficient low cost running.

The ailerons have been programmed to couple as flaps enabling a low airspeed for landing and surveillance. The dihedral in the wings provides additional flight stability, allowing this aircraft to fly in bad weather conditions.

Above: a view of the SAITO FG-20 four stroke gasoline (petrol) engine with plenty of power for this aircraft.  

The Telemaster Senior exhibits very stable flight, even in windy conditions, due to the power of the engine. Lift off and flight is typically at a quarter throttle, with plenty of power in reserve to carry heavier payloads, such as more fuel and /  or heavier sensors.

The use of a four stroke gasoline (petrol) engine provides about one hour and 45 minutes of flight time.
