Improving the Great Planes DC-3
I need some advice on the Great Planes electric DC-3. It has two 400 motors. I built the plane and flew it with an 8-cell NiMH battery. It flew great with no wind, but it lacks the power to fly if there's any wind to speak of. I crashed it yesterday when I let the nose get up in a headwind on take-off. I struggled to keep the fuselage level as I climbed out, and when the plane was about 30 feet in the air, I lost the battle. I simply didn't have enough power (or wasn't good enough a pilot, or both) to keep it from nosing up and stalling.
When I get it flying again, I'd like to add more power. Should I:
1) Use a battery with more cells?
2) Install larger engines?
3) Change the props?
Any advice is welcome. Also, I'd eventually like to try li-poly batteries. Would love to hear from anyone that's installed li-polies in the Great Planes DC-3. For example, what battery configuration did you use, and what ESC did you install?
