The marutaka me 109 is a very scale like plane.The main thing is to keep it light.There is a lot of blocks of balsa that need to be carved and sanded.I put robart retracts in, in the scale location and the ground handling was horrible,and had a very high wing loading with the extra weight for the retracts. The plans are very basic and you will need to fit parts 3 steps ahead to make sure it all fits together.
