i have seen many of these fly and all with great reviews. the only concerns i've heard (and this is almost unanimous from around here) is that you can't expect this bird to fly like an aerobat. 100% of the planes in taiwan have experienced some kind of failure on the right wing panel. some found cracking early enough to repair it but some found out in the sky, ultimately leading to a death spiral. they attribute the weakness to a thin airfoil, thus small adhesion/leverage area, and a short spar. like jmupilot said, it's better flown just above scale.

but flown scale, i truly believe that this is the best twin trainer.
