I can improve the performance of almost any plane requested, so long as it is a simple design you would see on the "New" page, and doesn't need the use of mods to function properly. Tell me what you want to improve in your design's performance when you send it.
I hope you like the upgrade! @TitanIncorporated
I never bothered making struts for personal builds, but I'd suggest using structural wings on the edges to connect both wings, and put fuselages covering the wings so you can actually place the struts. @owen200
