Hi Amir,

Your coil is doing as expected given the power and size (18-20 inches 
you stated). Javatc calculated 19.4 inches, so I would say your right on 
target with this coil. 4" coils can handle quite a bit more power than 
you are giving it and the other coils you are looking at which are 
similar in size are being certainly being driven with higher powers. I 
think your coil is doing superb! Congrats!

Take care,
Bart
