I have been testing the Dudek reflex wings on the Green Eagle and I must say they are fast. Lift is good on the 46 at over 450 FPM no brakes needed for takeoff.
The 42 is fast but only 375 feet per minute on climb out. for some that's OK. If you are going to fly a re-flex keep in mind they are fast but not very efficient on lift. One thing to take note of is fast wings in general do not have the lift of a slower wing that has a higher aspect ratio.
The test were done on the propane model which is the lowest thrust of all our models at up to 220lbs verses our gas engines producing up to 265 lbs. Standard tandems are getting over 500 Feet per minute but not as fast and not as smooth in rough air. Call for question as we will be posting videos of each wing we test with results. If you have a wing you would like to test, send it to us.
