Here it is from a different angle. The VAM is cut away to show the inside.

Paul,
 Is someone currently testing this configuration?  Is the original
VAM being tested?  Thanks

LimoEZPaul,

Ed Klepeis has had a request to build another one of these. It has been tested
twice.  The VAM works but it must have a shut off valve on the front to prevent 
hot gases from coming out at idle. At higher power it sucks in cooling air. This 
cools the exhaust gases so the exhaust gases are not as hard on a pusher prop. 

The VAM by itself is rather noisy so the fish tail was added to quite it down. 
Fish tails add a bit of thrust at high speed. It also looks cool as it can
be blended in with the wing trailing edge.
