On machine screws like linkages do you use Blue Locktite or Thick CA to secure the nut?
Reason I ask is I have a Edge 540 I just recently built and I used Ball Links and used Blue Locktite per the manual and because that is how I roll. Well almost had a disaster, during flight I lost an aileron linkage in flight. Fortunately got it down. FWIW my AR636 RX gyros saved my arse as it helped kept the wings level enough for me to land. Twitchy, bu tI made it down. It was my 3rd flight
Think I am going to switch to thick CA per Doc Austin.
I've used both, depending on the size of bolt/nut, Red/Blue Locktite and thick CA. Mostly on heli's and quads where vibration can be a problem. Never had an issue with either.....Although, a little heat may be required to loosen metal to metal contact after the Loctite has cured properly to larger metal surfaces.
I religiously use Loctite on Linkages, provided that they all all metal construction. I put Loctite on the Steering Arm Set Screw on my PZ T28 and the Plastic Base that the set screw went into dissolved within minutes. The extremely fine print on the Loctite bottle warns users not use on Plastic.
With the blue you must make sure threads are free of oil film. Clean threads with alcohal be for applying blue loctite. With using ca works well (even with oil film) but may have to use green ca remover to get threads undone (very big mess).
If using Loctite I'd go for red. The blue has quite weak hold and while it's fine for most applications on small threads where there isn't much area for it to get a grip it's not so good. As already noted, don't use Loctite on plastic.
I've used clear nail polish to great effect so far!
I have used that for several things other than planes. I kind or like the idea because it is fairly easy to break loose and easily cleaned with Acetone.
I think I will stick with Thick CA on this model. The servo control arms and Ball Links are plastic, horns are G10. Thick CA is easy to control and fairly easy to break off. Uses really small #2 machine screws with about 3 threads exposed after tightened up. Perfect for a drop of Thick CA.
I am grateful I had an AR636 RX in the plane when it lost the one of the Aileron Linkages. It helped me sit the plane down without a scratch. Only my 3rd or 4th flight. Anyway Doc Austin has built a lot of EF planes and gave me the Thick CA tip. Thanks Austin.
If you lose an alerion linkage you still have the other alerion along with rudder elevator and thrust to control the plane. Never lost landing gear bolt, tail surfaces or anything else. I have used "aircraft nuts" on landing gear.
And no, I don't fly helicopters.
I've never really lost bolts on anything other then the motor mounts on rc stuff. On car stuff I've lost 1 of 4 driveshaft bolts. The other three had lock tite so I must have skipped it on accident or forgot to snug it down. Only other thing I really use it on is clutch or flywheel.
