some more ideas, thin cardboard formed duct (like a tube from a paper towel roll), down the side of the cage, open up to a shroud around the fly. Fan mounted inside the tube. Reason for the fan in tube is to try and better muffle the sound of it running which has been my main reason for not using them in the past. Two exit holes on the top part of the cage that swings over the top. I suppose to be safe I should put a metal cap over the hole (spaced to allow air to escape) as an X-ray stopper although I highly doubt X-rays would be a problem.
I have discussed the issue of Flyback heat with another member of this forum, unsure of exactly what is causing the heat, since a lot of it seems to be in the HV tire, also since I am sure the insulation on the wire is fine at these temps, there may not be a problem even with massive wax loss other than the mess and perhaps the loosening of the mounting of the fly tire itself to the frame.
I am guessing here that the HV at say 25kv and 1-2ma avg about 35watts some of that will go to heat in the tire...
