Well, I used a transformer and it didn't help, in this configuration I took out the passive components and it will charge another 250Mah battery battery in about 1 minute, but it still isn't fast enough for hovering. If batteries are charged very fast, they'll cook up to a higher voltage than 9V, which is perfect, 8.4 doesn't work at all. After a while, they may be extremely high voltage cooked[frozen] from little use and high charge. http://www.4shared.com/document/BDqJ-mDk/voltage_multiplier2.html
The simplification might be to use a 9.6V pack and just let it die until you reach exactly 9V so it works on its own without extra circuits. Nice slices of copper is how to get around the pico ohm, although those are just for efficiency.

It provides about 11.46 Kwatts at 41.3 seconds and 5.5w at 21.65 seconds, I would say about 11Kwatts before the batteries won't recharge anymore, time for a generator capacitor. http://www.deerso.com/14ODX5UG_COPPER_COIL477222-details.aspx?src=gbs
