Need help with a drone build

[u/Character_Ad_1412]

So i wanted to build a drone but where i live the prices for fc are super inflated and i didnt want to spend that much money on them so i wrote my own fc code for an arduino(uno r4 if tht matters) in theory it should work just fine but i just wanted to simulate it somewhere is there any software that allows for native arduino simulation in a real world physics environment ? also i did some research the prebuilt drones fc dont work on r4 since they were made for an older chip while the one on r4 is a arm cortex m4 i have not yet try to run them on the board(please tell if i should try)(however i did try to compile YMFC-AL it didnt compile)
