hi
just been out for a flight and checked my props for play and one mount has some up and down play in it
do i need to locktite them ,and do you tighten them right up tight
thanks

Loctite should not be used around plastics.  It can stress crack them.  Motorcycle windshields have been known to break in half around the mounting holes when it was used on them against the wind.

See the "Not Recommended" part here:  http://www.loctiteproducts.com/p ... locker-Blue-242.htm

There is a Loctite 425 Blue that is safe for plastic to metal fittings.  Hard to find and sort of expensive too.  See the second reviewer comment on it here:  https://www.amazon.com/Loctite-A ... dlocker+loctite+425

hi
thanks for the info
i will just nip them up without using anything for now
and just check them regularly
cheers

Don't get them too tight, and do use a permanent marker to draw a line across the top onto the plastic so that you can easily check if they are loosening every time you mount the props.
