(I replied to this a little while ago but I guess it never got through. Hopefully it makes it this time =D )
Hi Terry,
It looks as if you have to hook the thin corona wire up to a positive high voltage in order to get it working. If the theory on this webpage is correct,

it needs to have a high voltage on the thin wire in order to get the surrounding air to become ionized and away from the wire. Also, you may want to check out this webpage:

Click on "Lifters" and then "Construction Guides". They have a couple of trobleshooting guides that may have some ideas that you (or me) missed. Hope something works. =D

P.S. I'm glad to finally see some posts circulating around now. Looks like this list is up and running! Thank you Steve Roys!

Hi,

I made a lifter once following the instructions at:

http://jnaudin.free.fr/html/lftbld.htm

I note the great successes of those at:

http://jnaudin.free.fr/html/liftbldr.htm

But "mine" did not fly :-(

I see they are lifting mice and stuff...

http://jlnlabs.imars.com/lifters/orville/index.htm

So "I" must have done something wrong...

So my question is...

I was using a Bertran 50kV 3mA "XR" power supply, but the "hot" lead is
"-". So the aluminum "skirts" were -50kV to the "ground" and the thin wire
was at basically ground potential.

I suspect that I need a power supply with "+" 50kV to ground to get the
thin wire part "fizzing" and thus provide thrust. I eventually arced the
wire to the aluminum which was "bad" in my case. I used aluminum coated
poly from a film capacitor for the skirt and it burned up... Something was
"basically" messed up an I think it was using a "-" HV power supply.

Any thoughts welcome ;-))


Cheers

Terry
