Product Review (submitted on December 20, 2017):

These are nice arms for the money. The threaded holes are metric which isn’t a real surprise. I retapped mine to 4-40. I purchased mine for Power HD metal gear servos. They fit the splines extremely tight. Tight to th point they are a real problem to get off the servo. It can be done by wiggling the very end of the arm for a considerable period of time. They get a bit easier after each installation. They cannot be pushed on by hand from the start. They had to be pushed on the splines with the mounting screw. Save yourself some grief and don’t run them down totally the first go, put them on a slight bit and remove them. Do this a few times and it goes much easier the first time you need to remove them from completely pulled down.
