My friend picked me up 2 planes and 3 eMax BLHeli 12a ESCs at Flite Fest last year. Finally built them and they won't arm with my Hitec Optima or Minima receivers. Seems this was a known issue back in 2015 (https://github.com/bitdump/BLHeli/issues/77). I tried 1-wire programming them with a DYS v2 programmer and an Arduino Uno but neither would connect. What is the fix for these? Why are they running such old firmware?
