Description

KSP Version: 1.4.2.2110 (WindowsPlayer x64) en-us

What Happens: Fairings produce an exceedingly high amount of drag

Mods / Add-Ons: none. Fresh install

Steps to Replicate: Build 2 rockets of similar size/weight and have one of them use a nose cone and another use a fairing

Result: The rocket with the fairing goes about 1/4 the distance compared to the one without

Fixes/Workarounds: don't use fairings?

Other Notes/Pictures/Log Files: Here are 2 example craft that I made to test with: https://drive.google.com/open?id=1MCIuAVxSSUg6OewV04_zFVf9HcR2O_Hl and https://drive.google.com/open?id=1rgqZnOxIuiXVC9fm0PUFAkZB8jSgcoLu

The example rocket without fairings (TEST) will go to about 520km straight up with sas enabled. the one with fairings (TEST 2) will only go to 130km

If you take my craft that has fairings and deploy the fairing before launch the craft will ascend to roughly the same altitude. Its as if the fairing is doing nothing at all.
