HSD L39 EDF 12s Maiden #2

This is the second maiden flight of my HSD L39 12S 120mm EDF following a an issue after adding a flap servo slow setting on my Tx. Although I had reduced the elevator flap mix setting to 0% on the Multi Function Control Unit in the jet, I left the mix live. This meant when I added the servo slow to the flaps it also added the servo slow to the elevator. During the pre flight checks I confirmed that the up and down movements corresponded to the Tx stick movements but failed to notice the slower speed of the elevator. Once the aircraft was airborne the reduced speed of the elevator made pitch control of the L39 more or less impossible. The resulting heavy out filed landing caused irreparable damage to the wings. A new set was promptly sent by HSD Jets UK and here is the second maiden flight. Thanks for watching
