Drop tank for Luftwaffe aircraft

[pufff]

The modified bomb to drop tank does not extend aircraft range/flight time. With the added weight, it probably decreases range slightly. 

As Kraut1 stated, the bomb fuses are deactivated. The drop tanks I implemented have some weight. They displace some dirt when they hit the ground but there's no flame,  blast, or residual smoke.  Here's a video of a 300 liter drop tank hitting the ground. https://youtu.be/mAgMsI3D9jk
