There are other situations, which I have mentioned before, where the rudder can save your life. If a non IF pilot ends up in IMC, which of course he shouldn't, the safest way to climb from a trimmed S&L setting is to apply full power, fold your arms in front of you, and keep the a/c on a constant heading using the DG and rudder only. It also works by keeping the horizon level, or the T&S in the middle. The same works on a descent starting with a trimmed descent at about 1600 to 1800 rpm. Try it.
