Air hogs also used to make some air powered toy cars. I do not know what they were called, but they might make a good rc test vehicle. I recently picked up an airhogs accelerator plane as a birthday present for my much younger brother. I also used to have one of the first air powered planes they designed many years ago. I'm pretty sure the engine is in the garage somewhere.
The hardest part is developing the container to store the air safely.
