What engines are on the delta and what size is it? I was thinking about a pair of piped Rossi/jet/Webra 32-40 class engines with short high pitched racing props. That is BS that deltas are not fast. A friend of mine radar clocked his single engine delta at 150+. Whether a twin is faster than a single I can not comment. However if the engines are in sync it sounds at least 20 mph faster than it really is (even if it is not that fast).

True story... everyone at my club thought I had one of the fastest planes there. (twin engine combat plane with a pair of .15s). I did a lot of low passes and got lots of echos from the trees. One guy asked me if I was breaking 100mphs.

I had 8x3 props turning about 18K rpm. If you do the math you know it was flying at about 50-60 mph. It just sounded like 100mph. everyone loved it.

I need a high rpm twin delta... that sounds like fun... (or a 3D B-17 even more fun)...
