I really like the design, and how accurate the cockpit is to real one.

To update BP on WS:
1) Copy your updated build,
2) In F10 menu, select the bp you used to upload to ws and in the advanced options find the option "replace with clipboard" or something like that and use it.
2) Publish as usual, it will open the WS page for the already published version,but you won't need to do anything here as it is now updated :)
