| I've been putting some #'s together for different power systems. So far the 8s2p with either a B50-20L and a 13T or a 8s2p with a B50-15Xl and 13T, blow away any combination of 4s4p, and other combinations like 5s3p arent nearly as good either..
Flight times with 8s2p are only 2 minutes less (20 min as opposed to 22), overall amperage is half (therefore same flight times), and motors won't get hot. My current 4s4p can pull upper 60A's, the other 2 will pull low 30's max and will hold their headspeed under hard load far better like half the drop in RPM at high load. High V is the way to go as high current causes big voltage drops in LiPo, more than they do in NiCd/MH.
I have heard that the C50's don't fit well between the frames and may need trimming. I haven't tried to put my C50-16XL in it yet for testing. My previous B50 w/heatsink fit unmodified.
Don't get me wrong, 4s4p works very well, a huge improvement over NiCd/NiMH, this high V is another big step above that. Serious power... |
