AtomRC Dolphin - Li-Ion Endurance Test at Cotter Dam

In my previous video, I made up a split 4S 4200mAh Li-Ion pack connected by a series harness for the Dolphin. (   • How to make Li-Ion Packs for the AtomRC Do...  ) Today I finally got to test it, and it worked really well! Maintaining a roughly 4A draw (remembering the DJI VTX and other electronics would account for over half an Amp), it took 45 minutes of flight to get the batteries down to 3v per cell - with a safety margin since the P42As can be discharged down to 2.5v. Unfortunately I didn't take note of the total distance travelled on landing, but did see the Dolphin was averaging 60 kph at this low power -- very impressive little foam mammal! It didn't seem particularly unstable, but would probably benefit from a bit more speed. With that test over, I'll probably cruise at 5-6A most of the time, as a half hour flight at higher speed will still cover plenty of ground and be more enjoyable. Music Credit: 1.
