loosen your elevator,rudder and wing clamps. pull the surface away far enough to have pin clear the mount. now tighten the screw to the clamp mount with all you got. i used a ball driver and did this to all the clamps then loosen and insert surface and clamp tight with confidence. i found before doing this i had the elevator clamps super tight with surface in and still i could pull the left elvator half right out with my hands........no matter how hard i tried to tighten it i still could pull it loose after. then i did the above and now it is tight as heck going no where now.. glad i caught this.........hope this helps others.

also i setup my full flaps with crow and used a flight mode linked to the flap switch to activate the use of a fresh trim for the elevator and ailerons when in the position half flap and full flap. this will allow me to fine tune the amount of down elevator needed when deployed and yet go back to level flight original trims when i switch flaps to full up pos 1...i have a starting amount of down elevator in both pos 2 and pos 3 using the flap setup but now i can override that by trimming while in that position and once on the ground i can transfer that added change of trim to the regular flap setting mode and get it spot on for future flights. then the so called sub trim in flight mode becomes a windy to calm day adjustment at best if even needed.

thats good practice with every clamp and it is indeed a valueable tip - thank you.
it is mandatory to always pull all control surfaces to make sure they are tight when you assemble the model at the field every time.
