Im just finishing assembling mine, I didnt find any of the parts particularly flimsy on my example must be a quality control problem I guess in fact I commented to my LHS owner on ow nicely the plane was built. As for the task of drilling six holes for the pull-pull wires a dremel sorted it in a few seconds. The only problem I have encountered in the whole build is that the hole for the lower wing locating peg was slightly undersize, I wish all the artfs Ive assembled were tis difficult
