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

What color did you use? There are 3 diffrent colors 2 you can get out again the 3rd is almost impossible.

Try heating up the screw with a soldering iron- this weakens the threadlock and you should be able to remove the screw. Be sure to use a decent screwdriver of the the correct size etc, one too small will simply strip the screw head.

but would that actually melt the screw thats y i never tried it lol

a soldering iron will not melt a screw.

Even if u had the screw on its own it wouldn't melt it - Its certainly not going to with all this other material around it to soak up heat

i used the red colour threadlock, is that still be possible to melt down that on the screw

always use the blue threadlock. i heard the red is almost impossible to get off. but you might be able to melt it

ty coz iam still new, next time i wont get tricked by the store and i give it a go melting the threadlock
