No substitute.....
I am using the Emcotec/Robbe/Futaba DPS2018 in two of my jets. It is most certainly better than the usual Sbus commonly in use. HOWEVER, I am also using the Powerbox PBUS (PowerBus) system on two of my latest jets - there is simply nothing to touch it. Do yourself a favour and check it out on the Powerbox website. In conjunction with the Powerbox Royal and with either the PWM or Sbus servo adapter hubs it does more than anything else and offer all the power drainage protection you need.
Cheers,
Jan
