I am assembling this Yak-I notice the stabilizer halves when tighten fully they seem to be a loose fit toward the trailing edge against fuse-they seem to move back and forth at the trailing edge when pulled from outside edge -any comments would be welcomed-thanks

My 35% 260 did the same thing after 150 flights. I have simply put some drops of thin CA over the stab tube to fill the gap between the tube and stab tube.
