When you dive with an 84, keep an eye on the ASI and never exceed 450 mph of indicated airspeed. Faster than that, you'll surely loose parts; till that point, you'll be able to pull out of the dive (pulling gently on the stick!): just keep in mind that this is an empirical observation, so it can be a tad more or tad less of 450 mph. Be careful.
Dive bombing is something I definitely advice not to do with a Frank, unless you are really fast at finding your target, aiming and dropping!
