"Guys I know this is way off subject, but what are yall useing for a throttle arm? I have a DL-50 that I just bought, that lil throttle arm is just way to short, I need a longer one so I can set up my throttle linkage. Thanks."

I am using a small blue 1" aluminum servo arm from a Hitec servo. I saw the idea here somewhere. Probably way earlier in this same thread. Works well.
