Default Removing V2 Tailrotor hub grub screw?

I have tried to remove two of these little grub/set screws and it seems impossible. The first I blamed on Align, cause I got it assembled, but the second I put together with blue locktight and now I cant get it free .

I am worried I am going to strip this one too and there is no way you can drill these little things out. Has anyone had this problem and solved it? I have heard that heating the locktight can release it? I considered putting the soldering iron to it for a while then trying?

Thanks.

Yes, heat should loosen it up. Also, make sure you are using a good quality hex wrench. The cheap one will strip it out every time.

Use the soldering iron first. If you did strip it, try a standard size allen wrench. I think it is 1/16. It is slightly bigger than the metric and works great on the grub screws once they are striped. Also if you used a lot of loctite, the tail hub maybe fused to the tail shaft. The soldering iron works great for that as well.

"Good" also means not using an "L" wrench no mater how much it cost. You need the ones with handles on them.

Thanks guys, got my Align drivers and they are REALLY good. The grub screw came out without complaining. Even some of the hex screws I thought were stripped came out fine. I thought the set of drivers I have were fine, but obviously not.........
