Thread: Goldbergh Extra 300S

My all time favourite model is my Goldbergh (kit) Extra 300S. She's 68 inch wingspan, weighs 9 pounds and is powered by a Super Tigre 91 two stroke. This aircraft has given me more pleasure than any I can remember. She is the most natural aerobat I've ever owned. Superb. 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?
