Have you made any progress on the ST? I've been bogged down in the holiday season travels and like you, needed to spend a little time cleaning up the workbench. I accomplished the workbench cleaning over the past weekend and hope to begin construction over the New Years holiday. I'm trying to decide what engine to use now. Besides the little gasser I posted the picture of, I picked up a Magnum XL 120 Four Cycle glow engine which would bolt right into the mounting rails on the plans. It's more than necessary to fly the thing, but then so is the gasser. Right now, I'm leaning towards the Magnum because I think it is a cleaner, more attractive alternative. I have another project that the gasser would be perfect for which I hope to build next summer or fall.
