Other questions, are you wiggling your elevator while the plane is turned on or off? While off some servos can be moved quite easily.
Stabilizer? what do you mean by wiggle? It will flex some, after all it is made of balsa not steel. I can flex the stabs some on all of my airplanes. You should see the dance the tail feathers on a Kadet Senior do when you run it up to full throttle on the ground yet it flys like a dream.
