I am a new insructor just begining to teach . I have flown two or three so called trainers that students brought to the field and must say I am not overly impressed. That is compared to my own personal favorate, the GP Ugly stik 40. I have an ARF that was given to me after a serious crash and I rebuilt it and it is the best flying plane I nave owned to date. Very responsive and stable. Is much easier to handle than the "trainers" I have been flying. I plan to start my grandson out on it today. There are at least two other ugly stiks on the field and they are all very impresive in there ease of handleing[ one being flown by a student of another instuctor]
