LiPo power...very cool!
Here is my AT-6 setup in full:
- MaxCim (MaxN32-13Y) brushless motor
- MEC Superbox 3.75:1 w/16T pinion (MaxGR3.75-1/4)
- MaxCim 25-cell Controller w/ 3amp BEC (Maxu35-25BEC)
- 26-cells CP1700SCR NiCd
- APC 15x10 e-prop
For a Lithium pack, a dual 4s configuration works great on MaxCim power systems. My ShowFlyer has one. You will also have plenty of power using a 4s and 3s pack combination.
My 26-cell setup was taken, as is, from another application but a 24-cell setup would work great also.
Good luck!
