Dear Members,
I feel that after almost 3 years of 5th scale I can fix most problems.
I am still struggling with removing stripped Hex Screws.
Sometimes I get lucky and other times it turns into a nightmare.
I finely sought out professional advice. I talked to a former machinist in customer service at McMaster-Carr Company. He started me on the right path and the bottom line is using the correct drill bits and extractors.
I purchased a set of bits and extractors and a 3 mm cobalt drill bit. Part # 2729A44 and 2753A164 see attached pictures. This is a great place to start. I tried to remove my first stripped hex screw and used too large of a drill bit and drilled off the head so I was facing the stud (BUMMER). Drilled out the stud and had to tap the transmission plate on my Vekta. I pull it off and was able to screw in a new screw but at a slight angle.
Any Landing you walk away from is a good one.
Anyway with more practice I hope to master the stripped screw scourge.
Sorry for the long post.
Best Regards,
William E. Burrows Jr.
P.S. Just found a new tool called SOCK IT OUT these extractors require no drilling. Just bought two sets one for flat heads and another one button heads screws.
I will advise if they work down the road.

Stripped screws are such a PITA. I had one when I was using the alloy engine mounts on my FG and finally had to heat the part up so much, it bent due to metal fatigue.

Sometimes you win, sometimes you can’t get a break!
 
Try this before you totally mess it up trying to remove a screw and can not get it to go. Take punch bigger than the head of the screw and smack it a few times. This will shock the screw downwards and relieve pressure on the threads because as you tighten a screw pulls upwards towards the threads. There is a slight bit of clearance in the threads and a lot of times you will see this will remove it. Plus you are now also smashing material into the area where the wrench goes and may have to tap the wrench back in. But this will give it some area for it to bite in to. I do this alot at work even after customers have almost totaly ruind a philips head screw. Took a punch and smacked it about 6 times real good. Two fingers on screwdriver and it came out. Guy said he was fighting with it last hour trying to remove it. This works good also on the Losi5 flat head screws on the chassis underneath that hold the engine in. Just one more thing for you guys to try before having to get out the screw extractor kits.
