Use the trim slider to open the rear doors. Activation groups 1, 2 and 3 drop the tanks - though activating group 3 results in the destruction of the plane.

This is NOT my entry for the tank drop challenge - it's a failed experiment that I thought was interesting enough to share.

This plane was never actually produced as a whole by Geekpride Fabrications, this computer simulation model is based on engineering studies carried out to investigate the possibility of submitting a new, multi-purpose heavy transport as a design for the tank airdropping contest. The studies identified many problems with this approach, including:

1 - The size and bulk of any such design would require extremely powerful engines. Current propulsion systems may not be capable of this performance.

2 - The insistence of the Paternian forces that the tank clamps be connected to any landing gear controls is both bizarre and problematic. Any landing gear could not be retracted until after the tanks have been airdropped, otherwise the tanks become loose in flight and pose a high risk of damaging the aircraft.

3 - Airdropping tanks from the rear doors is possible, but risky. The two tanks nearest the door can be deployed without significant problems, but the third one would almost invariably wreck the plane.

4 - The flight characteristics of the design are not very good. It is flyable and controllable, but it is not easy.


Recommendations:

Abandon the concept of a new heavy transport. It is not easily achievable with current technology, and would be highly expensive to develop and produce. Projected performance is not good enough to justify this. A more productive approach would be to create a single-purpose, cheap airplane that is simpler and represents more effective use of resources.
