Can they deliver more current for shorter periods?
Yes! This is the good news. Most models fall into the “Fun-Fly” or “Stunt” category. When the model gets an extreme amount of throttle control (very little full throttle and then only very short bursts) we can use a factor of 7C. An example of this is our Edge 540. On the BD301 it pulls about 8 amps from a 2 cell Li-Poly pack. Our favorite pack for this model is in the 2000 mAh range. However, we’ve flown in many times on an 1120 2 cell pack. Some quick math, 8amps/1.120(amp capacity of pack) =7.14. So, were flying this particular pack just over 7xCapacity or 7C! The model will still hover for 30 seconds at a shot a time and provides a very satisfying aerobatic flight. The pack works fine and no noticeable drop off. But, keep in mind this is a close in high power to weight 3D fun-fly model. The throttle is moving all the time and is seldom at full throttle for very long. Another example is an E3D. At 40 amps, we can get away with a pack in the 5700 to 7500 mAh range easily. This type o
