RE: Interactive Toy Blade Runner Helicopter
Hi Gordy,
The Kokam 340mAh cell is about 0.3oz compared to the stock 0.2oz cell. The flight time is about double and it does heat up the motors due to the extra weight and longer flights. It is best to let it rest like you are already doing.
Keep in mind that the high current capability (20C) of the Kokam 340mAh cell really provides a much higher capacity when drawing low currents on the Blade Runner. This is why mAh ratings don't always add up. For example, the stock cell may be rated at 300mAh at a lower current drain.
A different Kokam 340mAh cell is available from FMA Direct as a Lithium upgrade to their RTF Skysprite. I will be testing this cell out soon to see if the lighter weight provides a motor cooling benefit over the 20C Kokam 340mAh cell.
Remember that this magnificent design is created from compromise in many areas. When we disturb one compromise, another area may suffer.
