Subject: Fix for issue 1427 (YASim fuselage's "cx" affects drag on all axes)
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8cca0adc5893f5836de087de072f95d635ce22dd;p=flightgear.git

Fix for issue 1427 (YASim fuselage's "cx" affects drag on all axes)

Correct Airplane::compileFuselage() so that a Fuselage's "cx"
only affects drag on the X axis.
