I wouldn't use the EZ conectors on ailerons, rudder, or elevator on any plane above a 40 size, and maybe some of the 40 Size rockets migh need a more secure linkage.
Don.
I use them on GIANT SCALE Gassers all the time no problems at all!
However there is a simple precaution you can take other than the locktite, on larger planes, that solves all of the complaints about using quick EZ type connectors. I do this when I use EZ connectors on planes larger than .90's.
Just throw small collars with grub screws, ahead and behind the connectors, and use STAR type affixing circles, not the plastic ones.
The wheel collars will act as a secondary "backup" in case the EZ connector slips, yet these can still be adjusted quickly at the field.
It is almost impossible to remove the STAR type affixing circles without cutting them out.
Do it this way and you'll have something even more reliable to what those who DO NOT use the EZ connectors end up with.
You have to be careful with Z bends, some of the benders put too tight of an angle on the bend, weakening the angle and causing it to break in flight under stress.
Don't ask HOW I know!
