Are you addressing the video or the apparent low increase in top speed by adding the 2 forward facing engines? Yeah, it's no Osprey, but it is still around a 60% increase on the average helicopter top speed.
In other news I have dusted off my old books and I have decided to actually start designing an HPA rather than just talk about it. Going to aim to have got some prelim calculations and thoughts scribbled before an RAES competition in July to meet some more people and see what's going on in the world of HPA at the moment.
