beats me. We're still in business. Doing more sport stunt stuff than combat lately though. The Eastern Europe ARF's have killed off a lot of foam wing building. Though I did just get a call from a guy who built the SX 460 and loved it. 460 squares, plug in foam wing. Extremely easy to build, only about 10 parts. Got me to thinking I should redo the Gotcha Streak with a plug in wing. Makes for an easier build.
