    Once again i am cursed by the locktite monster. Another screw broken flush on a swash plate I was trying to recover. I heated the screw with a soldering iron but alas no luck. Is there a way to remove a broken screw without damaging the component (large goblin 700 swash plate)?

      can you cut a slot in it with a dremel, if not, it's off to the bin - :(, that's about your option

      Firstly was the bolt broken due to an accident or over torqued.
      More problems can occur when over torqued, what I have done to remove bolts, but also becomes more difficult the smaller they are, I centre punch the end to allow a drill to start, begin with the smallest drill work it out until a easy out can be installed.

      As per @overit's comments but it also depends on which Loctite you used. If it's a 262 or even a 243 then you'll need a fair bit of heat to get the Loctite to soften so you can remove the broken part. Once the Loctite cools down it will re-set so you'll need to keep the heat into it during the removal process.

      Thanks @mr_squiggle as allways very imformative and thank you too @overit. As the Heli was purchased second hand, I dont know what type was used. All I know is that its way stronger than the medium strength that I always use. One of the issues with second hand helis. I have never crashed the heli, and it is well built but the locktite thing is very annoying... At least it wont fall apart I suppose but it does not good to help with maintenance.

      If you do get the broken screw out make sure you clean out the thread. A trick is to get a bolt & make a cut about half diameter, parallel to the shank. Screw it in & out carefully, the slot you cut will collect the remaining Loctite & act as a tap does without the cost.

      I have had a lot of success with drill presses, often I can drill out the broken bolt it the component is able to be removed
