RE: Mini Ultra Stick
One other thing.
That charger doesn't look like it balances.
Lipo batteries should be balanced, preferably while charging.
The Astro Blinky lipo balancer is $25 at most hobby shops it is used along with a separate charger.
E-Flite makes a 3S balance charger that comes with the blade CP Pro helicopter. It can be puchased seperately for around $29. It charges through the balance connector but has a set rate of, I think, 800ma, so it would take sevaral hours to balance charge the recommended 2100mah battery.
