Ok so i made this with the idea being "Wouldn't it be dumber to make a single vehicle that can get the job done, instead of 2 vehicles like the challenge description said?" "Yes". Now i highly regret making that decision because now i have developed something that can handle rough terrain at 40kmph and can fly from Maywar to Snowstone, this thing should not exist, much less fly, but here we are.

Be VERY gentle with the brakes

During car mode, press AG1 and AG2 to fold the wings, press AG3 to turn the engine on and only use pitch to control the plane. Do not go above 90kmph and DO NOT touch the throttle.

In takeoff mode, Deactivate AG1 AG2 and AG3 and pull as hard as you possibly can. Just be gentle with her and she will work. When landing, do note that she stalls around 270kmph so you wanna try landing her around 350 gently applying pitch and brakes so you don't smash the props on the ground the second you land

And i chose to leave the cockpit with an open end because i wanted the pilot to actually be able to get out.
