pony: I decided i needed a little more area to get enough resistance to actually turnt he craft, but witht he speeds i want it to reach i felt the lead edge of the rudder would cause too much draft and cause too much strain on the supports for it, and pushing the back of the tail down, Which because the engines are going to be hardmounted to the frame means the engines would lose forward thrust and increase upward thrust, Causeing the forward speed to decrease, decreasing the drag on the rudder and causing the tail to rise again rapidly, Which.. would start the whole process over again unless carefully controlled with the side rudders. But That would cause possible tipping....
So in the end i decided to make the rudder longer instead of higher to get the same amount of area.
OMY: Ill be making a smooth and rigid version. Engine will stay rigid. Look in the first few pages to see a smoother version.
