Great minds think alike Sundevil
Since I discovered the Central Hobbies units a long time ago, I have not used much else. They just work well, look good are very light and are very strong. I did a "strength test" on a 3mm one a couple of years ago and stopped when I got to it holding up over 50kg as I don't have any servos in my planes anywhere near that power. The trick I have fouind with them is to use JB weld (as suggested by Centrals) and to make sure the rod is clean internally (I use a pipe cleaner and some Industrial alcohol).
