I don't have Ares brand but i do believe its similar to FMS brand plane based on size and parts design. This plane is small so if you flown a trainer before this plane will be extremely twitchy to fly plus its a low wing. I own several P-51D Mustang and if you still want it try go get a bigger mustang, the bigger they are the easier to fly. If you're on the budget get a 1100mm wingspan but if money not at issue a 1400mm wingspan size is very docile to fly.
Here are some of my video so you can compare the size between them and how it flies:
