Maybe I can answer this.I used microsens driver,balancer and wires which cost €160 or about $200 us.They recommend a 1s 3600 mAh lipo.I use a 5000 mAh lipo from Tower which is still smaller than a deck of cards.Depending on how long you keep the plugs lit I think it would last for a days flying.No voltage reg.Im new to radials but Im happy with the system.Easy to program but the size of the onboard unlts and battery sold me on it.Heres a pic of the balancer,the wires exiting the bottom go to the glow driver behind the firewall. Pete PS thanks for the link to the decals.
