Hello,

I am curious about the differences between the loctites. I have red loctite, seen blue loctite and heard purple colored.

I read in several posts that people using wrong type of loctite for servo horn screws and having troubles. For example pacer has red and blue.

So what are the differences and where to use which type/color loctite?

Engine carb screws?
Engine muffler screws?
Metal gear servo horn screws?
Engine bolts?
Blind nuts?
Metal to plastic, any need?

As I know the screw, bolt size detrmines the type/color, then what is the most all around loctite for RC airplane use?

I am posting this in beginners forum instead of questions so that new comers also benefit from the answers.

Thanks,
