If you have been converting planes with Legacy Importer, you may have noticed that your CG limits graph on the right-hand side of the w&b screen is all out of whack. The calculation of the CG as a % of mean aerodynamic chord (MAC) may be fine, but the fore and aft limits are set to crazy values so the graph is useless for knowing where the limits are. Here is the reason, and a fix.<br><br>In the aircraft.cfg of FSX models there are two optional lines in the section, setting cg_forward_limit and cg_aft_limit. The values are expressed as a proportion of MAC, so cg_forward_limit = 0.15 means the forward CG limit is at 15% of MAC. For some reason, a lot of designers set these at excessively generous values of cg_forward_limit = 0.0 and cg_aft_limit = 1.0, so...
