Hi Ed, list,
                 First a Big THANK YOU! to all the people placing the 
movie on sites and those kind enough to burn CD's for dial up users. I 
count at least 5 servers hosting it, you are awesome!
Ed, I will ask for more detailed height info when I see Bob again, likely 
near end of weekend, but he may call in by phone.
I noted there is some structure above the extra coil that should have a 
height figure for the record.
If you go to www.hot-streamer.com/mike2004/  area there is a drawing 
showing turns, wire size, etc and that portion for the extra coil looks 
like 8 feet diameter by 8 feet high for windings itself, then 8 feet under 
it of standoff but also a 20 feet height
so this could point to a ~ 4 feet "crown".

The distance to plane target, until I can talk to Bob, will have to be 
figured from the known diameter of extra coil, the size of people compared 
to model size as they placed it on the stand.
I was happy Terry managed, using that sweet digital scope, to pull off info 
from the sound track and place the BPS at ~72
for that test run.
I do wonder what that coil would have done with a toroid on top?
For those with the modeling software or fast brains, for a extra coil of 8 
feet diameter, what toroid dimensions would you have placed up on this 
thing? Again, all the known info so far is at above link.
Regards,
Mike
