Hi all.
I am impolite with because it is different from almost opinion. Because there was following weak points, I stopped using MK dual elevator coupler for my 2m airplanes.
1) Weight becomes a little heavy.
2) Play will be caused in some joints.
But, a delicate handicraft should be necessary when the standard Y-rod system is adopted. However, I use the Y-rod system of easy structure preferably.
Thanks.
