The only thing I didn't like was the "lack" od battery power. I think we could run it for about 10 minutes and then 30 minute recharge. What was the helicopter like for battery charging?
It's non-rechargeable I think, it's a specialised high capacity disc battery, the guy said it "lasted ages", he seemed to mean hours, don't forget water resistance sucks battery power like mad, & I guess the sub was heavier than the 'copter which weighed about an ounce.
