I am sorry for your experience, but its a nice aircraft for sure!
They are a miiltary trainnig aircarft and you need to treat it propperly.
Many real pilots (military and civilian) used it and flown perfectly for them, you need to use the trim for aileron too to compensate the torque and rudder too.
There is a switch on the fuel remaningn gauge that activates the digits (like the real aircarft does) the pilot need to use it… If you use the checklist this step is there to be done.
Its not a study level aircraft due its a military and it has classified documentation for it that make some parts harder to bring to the sim.
The 4 blades is Short Tucano not the Original Tucano (this one that is available has 3 blades and a quite less powerfull engine too)
Please join the Discord server and talk about what is too wrong to make you request a refund.
You need to fly it gentle and once you do that its very good flight and acrobatic aircraft to fly.
