I have assembled one (or actually two...).

Main landing gear seems to be little on weak side. It seems that guys on factory have tried to solder those wires together with not-so-great success. Its quite entertaining to realise after touch-and-go that you have rectractable landing gear...

So you should solder those wire joints and also make little aluminium pieces to replace those bubble gum like things, which are supposed to keep landing gear with plane. (Retractable landing gear, mk II...)

Fuel tank should be also replaced with something better, like Kavan. I have got two of those original tanks broken.

Also I have broke two engine mounts. Seems to be little on weak side too.

Anyway, I think that its great flying plane, at least I have learnt to fly with it last summer. I have now almost straight wing in it (there's just something like centimeter dihedral) and it flies even better, imho.

I had two kits (as those are sooo cheap...) and after second tank ruptured, fuselage was so soaked with fuel I just put radios and engine to new one.
