I have flown many trainers. All of witch have similar flying characteristics. My favorite to teach on was the Hobbico Nexstar Select. Trainers are simple enough as a learning tool. The alpha, hobbico, and many others make a line of trainers that is good for beginners because the model is prebuilt and pre-assembled.
You could even look into building from a kit. It is not very difficult as long as you RTM. The advantage of building is you learn a lot about the plane especially if you need to make repairs in the future.
As always get an instructor- Contact a local club teachers can be easily found and its generally free to have someone with you on a buddy box. Even if you feel confident about flying an instructor can teach you important do’s and don’ts that you would otherwise learn the expensive way.
