steel gear upgrade probs

[Robocop]

Hi
Ran my car today for first time having only one problem,car handles really good,however the larger gear i cant stop the grub screw from coming out,thread locked in place but still backs out any ideas.
Thanks

go to red threadlock but 1/2 of what you normally would use

That's odd, I'm treadlocked it with blue Loctite treadlock and I didn't have to do with it anything since I've built it. Maybe using more hreadlock should help.

I have used as much on each one but its only the top one that loosens
Weird

Might be some grease contamination in there? Can that affect threadlock?
