This year I've fitted a Genesis tuned pipe so I can get more manoeuvres in on the vertical up line, and I'm tempted to fit a Perry fuel pump too, but we'll see how the pipe goes first. Sorry about the crummy pix. Tried to find the originals but couldn't so had to use these crunched versions which are naff.

Keep thinking that if I enlarged the ailerons and elevator I could 3D it too. How much power would I need to hover 9 pounds?
