To add to this question, I'd also like to ask the following:
Is hiding the UI acceptable for producing video clips? It'd be nice to include cinematic shots of the F9/Nova-C throughout the various stages of the mission. Of course, this will hide any evidence of active modifications/autopilots. However, the original clips could be retained to prove flight authenticity if chosen as a finalist.
For the sake of the contest, I would assume that using the Innovative Machines logo within the video via the use of custom flags is permitted. Would this be allowed?
Quicksaves would be a fair and practical way to complete the landing of the F9 first stage while continuing the second stage insertion.
