@gunrunnerjohn posted:I'm curious in command why the requirement for AC? The first thing in the line of power is a bridge rectifier, it would seem that it would work with AC or DC for command. I can see why you need AC for conventional.
We've made a running change to the RSL4 that will make it function on DC. The first engine that will have it is the 2-10-10-2 and then the engines in 2021C2. It wasn't part of our original goal to make it work on DC, so it's nice we were able to get it there.
Bear in mind that on DC power, only Bluetooth is functional. There's no Legacy control or conventional control.
