Constant velocity

To allow the new engine to wobble on it's rubber feet we now have a big constant velocity axle behind the gearbox.
If the gearbox and propellor shaft were to be lined up perfectly this joint would not grease itself and wouldn't last long. The answer is to drop the engine down out of line.
This feels strange, having spent so much time getting things right, but we now have a four degree wiggle in our drive train.
