Not 100% certain but there is not much difference in the actual ball size of a 450 size heli and bigger heli's so think this will be fairly universal.,anyone else with any thoughts.

It will work on 450 and up to probably 600. Mine is to big for my 250 ball links.

as far as i can see this is used to put the black ballink in and turn it on the link without hurting you fingers.
i got this one in another version (wider, with wings)

Say you have a long rod with ball links on both sides. You can use one (or two) of these to adjust the length of the rod. The flat part that you can see on top engages the link and allows you to turn it. You keep this tool in line with the rod. Obviously, you use this tool when the link is off its ball joint.

This is used as a grip to screw the plastic ball links (black plastic hoops)onto the threaded rods, used for helicopter linkages. This is a really good tool for the money - no more hurting your fingers or trying to find two sets of pliers! *)

There is another Screwdriver included that has a Ball with a screw inserted. Attach the black end of the linkage tighten the screw in the screwdriver to make the linkage tight on the ball. then take the above piece slide it onto the other end of the linkage and turn. it will tighten the linkage with ease. hope this helps
