My 30 has a longer alum arm that came with it and can be used to lengthen the throttle arm out very much like the steering arm, I also turned it around so it was pulling and not pushing it. If a person uses it as it comes the throttle throw is very fast and is not desirable for most flyers. I use a good servo on the throttle and leave the spring in tact, reason being if I ever had a throttle connection failure the spring will at least pull it back to an idle or kill it.
