Well, I ended up getting the Twist and will hopefully maiden it on Saturday. It was a nice easy assembly job, however I had a hard time getting the OS 46 FX to fit in. I had to cut a notch for the needle valve, and with the fuel line coming in at 90*, its next to impossible for me to fit my fingers between the engine and the firewall to remove the tubing for filling. Is there a special tool to use that wont damage the tubing? I heard that the needle valve can be positioned verticaly, however I couldnt see how to do that. (Its a used engine, didnt come with a manual)

Here's hoping the first flight lasts in one piece.
