Now that you say you have only flown micros and park flyers you really might want to take the advice to start with a low wing glow trainer, gas engines are great fun and sound even better, but there are things you need to learn before you get a gas engine as well as the size of .40 size aircraft, especially warbirds. This weekend was my first time I flew a true scale warbird, a .60 size topflite P-40 with a DLE 20. I have the GP .40 sport scale Mustang and I wouldn't recommend that to you yet either. A tower .40 Kaos would be a good low wing trainer for you, this is probably not what you want to hear, but some of us have learned the hard and expensive way.
