Dynalifters are hybrid aircraft, they produce lift half from helium buoyancy and half from lift generated by the wings. Since these are heavier than air craft. their flight controls are much the same as a conventional airplane. For further information about Dynalifters please visit http://www.dynalifter.com/

One thing to keep in mind when flying a Dynalifter is that they have a very large surface area to weight ratio, making them very susceptible to cross winds. Try to keep take offs and landings as into the wind as possible. Also, they have exhibit a lot of slid slip in turns, so be prepared to use a lot of rudder to coordinate your turns.

Landings are basically un-powered, landing like a glider. If you are landing with a significant amount of fuel you may need a little power. Basically, you want to come in with the pitch close to 0 degrees.

Here's a few useful specs. :

Take Off Speed: 75 kias
Cruise Speed 100 kias
Landing Speed: 70 kias
Climb Rate: 500 - 1,000 fpm (depending on payload weight)
Decent Rate: 1,000 fpm
Cruise Altitude 10,000 ft.

The PSC-3 come preloaded with a 50,000 lb cargo container (it's a "weapon"). 80,000 lb and 100,000 lb, containers are also included in the weapons folder and may be loaded in place of the 50,000 lb container as desired. As the payload is in the form a "weapon" set the payload weight in the Weight and Balance Screen to 0.
