Great! I'm looking forward to your signal. Some years ago i also worked 
with kite antennas on LF and VLF. In the first experiments i've built 
e.g. a J-antenna for 160m, i.e. a 82m vertical wire and a transformer 
cable to transform to 50 Ohm. A used a call-E PA running 600 W at 160m. 
The PA worked at 36 V (using 4x IRFP 260N), 3 car batteries switched in 
series :-) It was all portable and i had CW QSOs with Japan on 160m m at 
lower power levels :-)
Great great great times!

What type of kite are you using for your experiments?

Good luck to all kite transmitting stations :-)

73, Stefan
