I have something similar to these TowerHobbies.com |Associated Factory Team 7-Piece Hex Driver Set from my R/C car racing days. everything has set screws on rc cars so lots of experience with that. The set screws strip so easily but the tools they make specifically for R/C are like this brittle hardened steel, they fit perfectly and they will break before they lose there shape/get rounded edges/strip out the set screws. I don't know the exact sizes for all rda's but I highly recommend something like this over anything you'll find on Amazon, been there done that and it's actually nice to find a new use for these old allen drivers I have lol
Thanks. Definitely checking it out!
