I have a few plastic bellcranks zleader. You can have one to cut the arm off. I'll be at the depot tomorrow and will probably go on Sunday as well to watch the TCS races. If you have a chance to pop by, or preferably race with us tomorrow, I'll give you a plastic kit bellcrank bro. I have at least 3 of them.
The xray servo saver mounts on the servo like a kimborough/tamiya/top servo saver. It doesn't replace the bell crank. I suspect it has stronger springs though.
