There are some interesting things that I accidentally learned on my X-DR.29 aircraft: 1. Although it is a light fighter, the X-DR.29 is quite weak in maneuverability compared to the X-DR.Mig23 and X-DR.F4; 2. When I let the X-DR.29 compete 1v1 with the J-15D PEA, Su-33 Flanker-D PEA, it almost always won or maybe I was lucky; 3. The X-DR.29 was a failed product but because I was lazy, I saved it.Some interesting things
