Parkzone Micro P-51 Engine Oscilation/Quiting issue
Notice -
If you are using the Zippy batteries from a Chinese Hobby store: These batteries are 10c
batteries. If you look closely at the battery supplied with your P-51 you'll notice it's a 20c
battery. The low amperage of the Zippy batteries will affect how the motor and ESC react to the
demand. The motor will start off normal but as the motor continues to draw power the capacity
of the battery to supply at the rate the motor wishes to use, conflict, causing the motor to
surge. Some batteries it will happen within seconds some a minute or two into the flight,
sometimes the motor will just shut off.
The Fix-
You can buy a battery connector part from Performance, solder the connector onto the PC board
so the batteries are in Parrallel (black to black, red to red, or maybe it is white to white and blue
to blue - keeps it at 3.7 volts). This will give you 276mah battery @ 20c capable, problem solved.
Weight penalty of the extra battery and wire, but, will allow the use of the Chinese batteries,
Bonus is, flight time will increase due to the larger "mah".
Part for the Cessna, same connector:
