I would like some help making this more stable, turn better, and just overall improvements. And maybe help with the landing gear. Also, does anyone know how to make sirens, like the stukas? Because that would be a thing id like to incorporate into this design.

Fictional backstory: it’s 1939 and following the success of the Stuka dive bomber, and taking inspiration from a crashed, captured Stuka, the SW.A.F Design Team started work on their own, fixed gear dive bomber. It was to carry 14 2.5 inch rockets, and a 250lbs bomb instead of just bombs, although it also had 37mm auto cannons mounted in pods under the wings. However, unlike the Stuka’s armament if 2 forward facing 30 caliber machine guns (and one in a turret in the back), this aircraft was to have 4 20 mm cannons, and 6 50 caliber machine guns making it a deadly weapon against infantry and lightly armoured vehicles. Anything more heavily armoured was taken care of by the rockets and/or the 37mm cannons. It saw combat as a dive bombing and ground strike fighter bomber until it started being used later for reconnaissance, requiring only a camera mounted where the bomb usually went. This aircraft also had an extremely high top speed in a dive and, thanks to its sturdy wings, could occasionally reach near 500mph making it one of the best boom and zoom aircraft of its type. This was thanks to its sleek futuristic nose, and its solid steel leading edge reinforcements and struts through the wing to provide ridigity. It had a few flaws however. It’s landing gear occasionally suffered and it had poor pilot visibility when on the ground, causing many aircraft to veer off of the runway into trees and other surroundings, even going as far as one crashing into a munitions warehouse, causing major damage to the air base in question. These factors led to trials being made for a carrier launched variant, which could have a nose wheel to help solve the visibility problem, but these too suffered landing gear problems and by the time they were fixed, it was too late to introduce them to service.

Thanks for looking at my plane!
This was my first fictional backstory I’ve ever written, so tell me if there are any things I can improve. Enjoy!
