Small as an RCE200 D-Switch, this inline servo signal processor lets you run a forward-only ESC on a transmitter toggle switch -- without paying the penalty of high starting current and mechanical drive shock. Just select the max delay time with the onboard DIP switches, plug into your Victor SC, Thor SC, or Astroflight ESC and you're ready to go. Comes premade with 6" male and female Futaba J plugs.

It also doubles as a signal booster so you save $10 on buying that for your IFI spin controller!
