RE: On board battery charger
Nah, the ignition has it's own battery. Many people have complained about the ignition hogging so much current. I guess Horizon or Hanger 9 is looking into it. But for now, he's kinda stuck.
I believe he's running a 1600mA 4.8 battery for the ignition. It'll suck dry in about 10 minutes.... Ok, not completely dry, but low enough to worry about. That's not even a tank of gas! I mentioned running two on a y-cable, but that still 20minutes with 2hrs of charging.
The Sullivan is still the only one I've found, and I haven't even found anyone who sells it yet. I used all the "where to purchase" links on the Sullivan website.
Guess I'll keep looking. An extra battery is kind of a temporary fix really. Maybe two 2500mA batteries. I don't think the plane will care about the extra weight. It's huge!
I'll look up the a123 batteries too. I'm not familiar with those.
