Sling Pilots Forum

Question for HW builders. Is anyone installing Cies fuel senders on their HW and are you replacing all 3 (2 main and 1 header)? I contacted cies and they said they were not familiar with HW and have only worked with Sling TSi.

I specified CiES fuel senders for my factory built HW which has just completed test flying and is about to be loaded into a container for shipping. Early last month, I requested confirmation that they were installed in both wing tanks and the header tank and the reply was yes.
