<< How much power could I expect from a flyback driven by a single transistor
 circuit? I've done some coiling but stopped over the summer but now I want to
 build a small high efficiency twin coil. My goal is 12" sparks between the
 coils which I calculated to need about 40-50VA which using the addapted 
version
 of power to possible spark length out formula of (VA/2)sqrt times 3.4 could
 give me as much as 17" at 50VA, leaving room for inefficiency and still able 
to
 produce 12" sparks. My original idea was to use an OBIT but limit the power 
to
 40watts with a flourescent light ballast. I then decided that a flyback might
 be good because it could be battery operated for complete self containment 
and
 would use the full potential of the transformer while the OBIT would kinda be
 wasting its ability. So basically could I expect at least 40 watts from a
 flyback?

Yes you can get 40 watts out of a flyback.i have pumped in nearly 30v with a 
4.5 amp variac supply.

Big powerful arcs.I have seen others that used like 120watts.You need a BIG 
flyback else it dies.
