Well trust me.... that CMP WILL NOT fly like your sim, in fact it's a real handful to keep it from snapping.

The issue you'll have with most of the newer models that size is that they'll be electric powered, some provide the option to go with a nitro motor as I believe the AJ Laser does, I know you can do either on the bigger models. Here's a 48" Extra 300 that will most likely fly even better than your sim but I don't think it can go nitro and it's only $180.00.

Do what you want, you asked for help and you got it. If you choose to ignore that advice, so be it.
