I just started running the Ofna clamping style aluminum servo horns. They have the same length as the stock one but I needed to space my servo up to clear the radio tray with turnbuckle. Ofn10774
I never broke a stock horn but I did notice a lot of deflection in it when forcing the servo saver by hand. Yes that may help act as an additional "servo saver" but i prefer to use the actual servo saver for that. I also run a 7955 so broken servos are never a worry on my mind.
