That would be an ideal solution. However I presume that any test pilot
will want to see this thing running at full power on the ground for
several minutes, before taking it out for a test flight. So, I have at
least get to that stage. I haven't dare to test it yet, but I would be
surprised if I can run it for two minutes at full power at the ground
without overheating it.
