Here the thing: a friend of mine has 2 years of training/experience on a trainer plane. He's done everything possible thing with it, including loops, twists, inverted flights

Now he wants a step up the ladder. We looked for a suitable succesor kit, and came across these 3 model:

Great Planes Easy Sport .40
Great Planes Dazzler
Great Planes Tracer .40

According to the mfg, all planes have "excellent aerobatics capability", yet are easy to handle...

Which one should he get ? Prices are about the same, and all would accept the OS .46 engine he currently ownes.
