[NSRCA-discussion] bullets

[Ronald Van Putte]

I have gotten these "no bulge/slotted design" connectors from two  
sources:  HobbyKing and BidProduct.  You have to look at the pictures  
carefully to see that they are the "no bulge/slotted design".

I really like BidProduct for acquiring large quantities of the  
smaller items, like connectors, extensions and hardware for my small  
hobby shop.  Many items can be purchased with free shipping.
