Hey guys!!!

I have a strange issue with my DL50. When I perform a wall the engine sounds like it wants to stall. Fortunately it never did, but my legs shake every time i wall my Yak. Performing a wall i speed up the plane horizontally, then cut the throttle and after 2 seconds or so i pull the elevator . And in the moment of rapid stall of the model engine wants to quit. My previous DL50 didnt behave like this.

Any ideas? Carb is well adjusted, i have also installed a nipple to the mambrain cover and connected to a long fuel line into the fuse.
