On my 1/5 Clipped Wing Cub, all the holes for mounting hardware or joining sub assemblies were pre-drilled and in the correct location. The landing gear was very scale like and strong.
I have the 40 Ultimate and again the same thing, All holes pre-drilled, hardware is excellent. Overall quality is great.
