@Aireal Anarchist it's not quite as stiff as same size of music wire but close, and most importantly, cheap and abundant! Lol I love using the .023 on micro builds, it just fits most micro servos. If I have to run .023 very far i'll use a little coffee straw or poly tube as a guide (or go with .035 or .040)
And I'd you dont have a welder setting around your own shop, any exhaust shop in town would give you a couple feet for a handshake...
