Curious, Jim, how your Javelin model (twin cox 020s) flies. A "Dr. Scribbles" is offering the plans on ebay. I suppose it could be updated to twin edf's, not sure how big. I have seen another Javelin crash in a loop when the tail became unresponsive due to the wash from the wings. Also curious as to the weight disadvantage using FG vs solid foam structures, and also vs. built up balsa covered with monokote. Jets need to be light as small edfs are anemic at best.
