Got one of those and it's a fantasic plane to learn on.
I bought an ARF version of it so I can't really comment on the electronics that come with the PNF version. However what I can tell you that after burning a motor that was already bigger than the one the ARF comes with (judging from pictures) I ended up with a much larger motor (I'll get back to you on the kv and exact size and prop specs soon) and a 60A ESC 2200mAh 3s lipo on a 600-700W power setup. With that it does go vertical and still glides perfectly well.
Anyway few pointers on building it:
1) The wings are really soft out of the box and there's a stupid design choice in them where the center spar ends and then theres a bit of nothing but foam before the outer spar begins. So there is a spot on the wings where its super spongy and flexible. Either way the easiest way we found to fix it was by sticking glass fiber tape (this sort of thing
http://i01.i.aliimg.com/photo/v0/323647 ... c_tape.jpg with endless unidirection fibers) on the bottom of the wing all the way from the centre to the wingtip.
2) The way the stabilizers are mounted is also pretty rubbish and flexible. Put some epoxy between the vertical stabilizer and the fuselage after youve mounted it to give it some support.
3) The EPO hinges are almost universally too thin and look dangerously close to falling off after a few servo movements. Putting some additional tape into the hinge should make it sturdy enough to never give you any problems
4) The clevises arent great, not terrible but not great either. You could either replace them or suport them with a bit of shrink tube. Also for safety you might want to put some epoxy on the controll surface horns after you've mounted them
5) Mount the flap servos in such a way that the flaps are already quite far down (30ish degrees) at servo centre (a servo tester makes life a lot easier in these situations) and that theres plenty of room for the servo horn to to pull the flap down.
You'll want enough throw in your flaps to make flaps full down look something like these:
