3S A123 Trex 450

Target at 3D

@15T, 3000kv 450TH, HS 2300-2400 only.

3s A123 is 230g. However, the performance is far poorer than a 3s 2200mAH 18c lipo. Cos the voltage is low <9v>70 oC. For gentle flying, 3S A123 is perfect. Or you need a higher kv~3800 motor for 3S.

Another picture is a 3s lipo curve, @14T/ HS 2700-2800

Max power ~250W. Current <20a.
