RE: Twin engine speed planes
How about the beautiful full composite DeHavilland DH-88 Comet made by Airworld?

RE: Twin engine speed planes
Good call on looks and speed. I always like the looks of the comet.
Bob, The RC Report article on the composite Duelist wasn't so hot if I remember right. I would rather the .25 size since I have a bunch of older race engines about looking for a nice sport home.

There is something desperately wrong with anyone who puts twin engines on a delta airframe.

Kelly Johnson did it on the SR-71, it worked out pretty well for him.

I was thinking the same thing myself...

He might have been trying out some real dry humor? [

If I was into electric power I'd try out a real streamlined twin semi-scale job.
The SR-71 I scratch built is a good flyer with .074s, but it just isn't fast with 3 or 4 pitch props.
Not being able to kill the lone running engine after the other engine quits has been the only SNAFU.
I would rather set it up with 2 fuel line pinchers than have working throttles.

RE: Twin engine speed planes
We built this baby as a test airframe a few years ago. Push-pull with two ZDZ 50s. Not a speed plane but it turned out to be pretty darn fast. I recall it could do around 110 knots (135 mph) in straight and level flight not tuned for speed. With the right props probably 160?
