I built this plane a few days ago, and it overstresses when using the elevators and flaps simultaneously. It also flies pretty slowly, and I've tried to fix this by changing the propeller size and shape, but it's barely helping.

Currently, I use a diesel engine with diesel fuel, which can be swapped to fix the overstressing, but I still can't find a solution to make it faster. I am kinda new to create aeronautics, so any recommendations would be appreciated
