This is a test airplane for the fuselage and props parts. I used the fuselage as nacelles for the engines but this was quite tricky to do. I've also been playing with how the props work and found a new way of setting them up. All of the throttle and pitch are controlled with just the VTOL slider. Pitch is set to -10% by default so you can knock the VTOL up a tiny bit and the props will spin, this way the plane can reverse slowly or stay stationary but also leaves the brakes free for use while the engines are working. This looks great for taxiing and makes it all much easier. Don't forget to start the engines first with activators 1, 2, 3 and 4 in any order you like. To take off line up and put the VTOL slider to half way up. For take off without pulling up just put the VTOL slightly above half way. The engines will over speed past the half way point so do not exceed except to get a temporary boost. This plane can also land with only 1 engine active.

EDIT: Whilst flying it is possible to use the top quarter of the VTOL slider to achieve 500+ mph whilst controlling the overspeed by increasing the pitch angle. It requires constant attention though as at 500 and the VTOL all the way up the engines can still continue to overspeed, so bring it back to centre for a couple of seconds to fix.
