Well said Adui. I have lost count of the amount of times I have needed to borrow a hex wrench or a small part like a clevis etc at our club. You usually have two or three people rummaging through their flight box to help out. Same with props and anything else you can think of.
I will gladly hand over bits and pieces to keep a fellow modeller in the air.

Thats one thing I like about this hobby. Everyone I have come across is more than willing to help. This is one thing that makes this sport great.
Everyone socialising and having fun.
