For shure that the F-18 balsa will be a stronger frame and by is shape and aerodynamic style it will cut straight into wind,, and motor is more into the straight center fuselage jet blast aera then the A-10 with out side nacelle that gives him a more expose danger to come off if hard landing,,, I guess if you go with brushless,,$$$ with the F-18,,, your chances are more up to a 100% secure cause of that,,,
