A lot of people don't like them, but I use EZ connectors on a lot of planes up to 90-size.
The trick is to hold the connector with a pair of pliers as you tighten the screw, don't just let the pushrod hold it from turning because you can't tighten it enough that way.
There is a special little wrench which is specifically made for the EZ connectors. I have a number of them, and I seem to remember getting one at the same time I bought the connectors. Maybe it came in the package with the connectors, or maybe I bought it separately, I can't remember. Never- the- less, it fits over the EZ connector's hex shape like a "box end wrench" and holds the body of the connector from turning while you tighten the set screw with a screwdriver. I always keep one in my flight box.
