Hi,
I gave up on loctite...I just didn't like the fact that it was either not strong enough or too strong, and also didn't like the fact that once you broke the bond, you had to redo it and let dry...sometimes at the field, i don't want to wait to let it dry and it's really not fully cured then anyway. I use 'goop' (zap-a-dap-a-goo, shoe goo, pfm, etc...) It has a flexible bond that holds the screws in, yet won't them spin out. I also use 3x6m hex cap screws in all my metal geared JR servos. It's easier to get them tight and it just makes it look neater to me. That goop works great on other bolts like landing gear bolts and other bolts you don't want vibrating loose. it really works great! Give it a try.
