Can you make model planes, tanks etc out of aluminium?
Answer:
It is doable. Obviously you've done it yourself! Aluminum airplanes may seem tricky at first, but in reality many full size fully operational planes (e.g. Cessna 180) are mostly aluminum.
If you want to go the RC route, the two main problems are weight and interference from the metal. You will need aircraft quality aluminum for the project (0.016-.032 of an inch thick), and you will need to follow many of the specifications of real sized planes to stay light enough (lightening holes, etc.)
Have fun!
