I agree with both guys above to a point.My 2nd plane was a Hobbico .40 Extra 300.Learned on a Kadet MKII.Got to where I could wring the Kadet 3-4mos after I soloed and got the Extra.Now Im not the most gifted pilot by any stretch,but I was mindful of my limits and my wallet when I flew it.My dad did the trim flight and then it was all mine.It was never crashed and I sold it about 3 yrs later.If you decide on an Extra,get a real one.By this I mean a true mid wing,not a low wing with the belly pan filler thing.Im not sure why,but the real mid wing ones seem to fly a lot better.They seem to slow down better without the tip stall problem.Ive always thought if a person could only have one plane to learn and progress with,it would be an Extra 300.JMO.If you are just flying circles with the trainer and still have bad landings,an intermediate plane may be better.
