RE: ARFs?
All of the OMP planes are just as easy to fly as a trainer. However you need to set dual rates and expo.
With a good computer radio you can turn the most stubborn plane into a trainer. You just need to lower the travel distance down to where you are comfortable. I would recommend you get an instructor to set your dual rates for you before you try to fly it. As soon as they lower them down for you, your plane will fly like a trainer. Just every so often let the dual rates out little by little. The more you do, the better you will get! Just be patient.
Also think about getting a simulator unless you already have one. Theres nothing more pleasing then hitting the space bar on each crash versus carrying a busted up plane to your car while your practicing 3D.
What kind of radio do you have?
