Screwed

Get a smaller driver and tap the edge of the screw. It should bounce out after of taps !! And then proceed to drink Ha !!!!

THAT SUCKS! I'm with camo, drink some and tap on it. If it comes out celebrate with a drink, and if it doesn't, drink to drown your sorrows, the repeat.

This may sound crazy, but I had the same thing happen and used a sewing needle between the broken bit and the inside of the screw head while holding a really strong magnet (rare earth) near the screw head. After a bit of poking around the broken piece, it loosened enough that the magnet pulled it out. I might have just gotten lucky, but it worked.

Ended up drilling out the other bolt, and got one out by regular method. That just left this one, which couldn't be drilled out due to the hardened bondhus bit stuck in the head. Last resort was applied; large crowbar snapped the motor mount off, and pushed out the broken bolt. New HR motor mount on the way. This was not a smart idea by Arrma.

I never use a ball end driver to loosen or tighten bolts. Especially with thread lock on them...

I surprised it didn't come out ! Did you try heating it up ?

@Camo lol I broke my soldering iron while attempting to do that.

UGH that mega blows. Everyone wants to save a few bucks where they can BUT please do yourself a favor and buy the 3 pack of M.I.P wrenches.(1.5,2,2.5 mm) It's times like this where we wish we had !!!!

I have fixed issues like that several times for both myself and others, hit it with a good hit of compressed air and it will push it right out.
