iPhone 5s "touch ID" VS. CA glue
 

Surprise... CA Glue wins. I guess Apple didn't include any model builders in product testing.

Bummer. At least I didn't glue my thumb to the phone (this time).

LOL.. I hate it when that happens..

Late one night (4am) after a marathon 9 hour Heli build I had finished and was pleased with the result..

I decided to lube the tail slider and rear bearings before heading to bed..

Next morning.. it was locked solid.. I had mistakenly picked up the CA glue instead of the the Oil..

Another hour to install a new tail and maidened her shortly thereafter...

Doh! It's always something at the end of those marathon builds isn't it?? The opposite happened to me when I used the wrong threadlock on my tail rotor assembly and it parted ways on the (thankfully cautious) maiden flight!

Good news. The fingerprint sensor reads my still-CA-crusty thumb the next day. Must have just been the freshly-bonded thumbprint that caused problems.
