last yr due to vibration of the engine, the screws attached from the bottom just come lose instantly, so i asked the staff working in hobbies shop, they told me to use the threadlock glue to put some on the screw and screw it bak in and it shoudlnt fall out. However, it works, the screw didnt come lose again but i cant get the screw out due to its tightness and that locks the whole engine up and i cant adjust anything or take it out. wat should i do
