Back Back to Battery index.


In September 2001, I bought a 'Hornet' helicopter package, including batteries and charger, and started keeping records of the batteries used for this and other electric models. Prior to this I had used Nickle Cadmium batteries for various types of electric flight using only basic charging methods.

Note L47: Flight time originally started at around 8 minutes. At 23 cycles, flight time reduced to around 5 minutes and would 'die' at around 3 minutes and recover after a rest. For interests sake use continued until 40 plus cycles when overall time was down to less than 3 minutes.
