That's a nice plane, and I also suggest the Aeroworks 260. It is smaller than the EF, but also a tad lighter. It is just a great all-around plane. The EF is a larger plane but very light for its size.
The problem with your h9 260 was most likely that it was too heavy with a 50 in it. it only has a 78" wingspan and like 1100 squares. Yours is not the first I have heard of to hae tipstalling problems.
Regardless of what you get, make sure it is at least 82 inches in span, 1300 squares or more, and under 18 pounds.
