Ron,

3 minutes??? Don't your numbers on the Dyn-E-Max assume you're flying full-throttle all the time? Just one of those fans would take off and fly this airplane. The E-Turbax equipped one flies at half throttle! Not every jet needs to be a paper airplane to fly nicely. This bird flies and glides BEAUTIFULLY with the twin E-Turbax setup, so the added weight of the Dyn-E-Max setup would scarcely cause the airplane to fly badly. Saving some weight and adding a minute of flight time would hardly be worth the realism you'd lose (sound-wise) with the TJ setup. At some point, what's the point of having a scale jet if it sounds so unrealistic? The Stumax sounds GREAT and the Dyn-E-Max sounds AWESOME.
