Hello,

I just purchased a Hausler 450 from a craigslist ad. I brought it home and hooked it up. just raised the throttle to the point of the heli sitting lightly on the ground for a couple of minutes. I didn't bother to lift off as I didn't have any training gear. 

After a couple of minutes of running, the blades wound down almost to a stop, as though the battery ran down. I put the machine away and put the battery on charge for 2.5hrs. 

The next day I set it down with training gear attached and the blades spun for approx. 30 seconds, then wound down again..

No when I power it on, the ZD-720 gyro light flashes, glows solid red for a second, beeps, then begins to flash again, and all the servos begin to move in and out, up and down. 

Nothing really happens...

Does this sound like the battery is shot? 

It's a 2200Mah 3S 20C 1.1V

If I wait a few hours and then reconnect the battery, the blades will spin for a couple of seconds and then wind down again...

Any advice would be awesome. 

Thanks,

Chris
