Well I maidened the ST today, and it flew great. I only got one flight, hoping to have more tomorrow. I only had one problem. I seem to have a fuel tank issue though. After I fill up, fuel starts to run out of the carb line. It doesn't matter what line I fill up with, or whether or not I fill up with the carb line connected or unconnected, it just keeps running out. I have never had a problem like this on any of my planes. I have the tank mounted in the stock position, and a Saito 125 mounted inverted. Would a Cline regulator fix this issue?
