I've extended the nose and tail. Basically lengthened the fuselage. I moved the wing from the center to the bottom of the fuse and also moved it forward. I also increased the height of the vertical stab and made the rudder and elevator a bit larger. Then I added ailerons.
Building it however, it's still just a Mini Scout with some modified shapes. As soon as I add that wing we discussed, it's really only marginally a Mini Scout. That's another reason I've been reticent to do so.
The Mini Scout is such a simple build and I wanted to be able to do some crazy stuff with an easy to build plane and an inexpensive powerpack. I absolutely love my Mini Scout Biplane. The Mini Scout Speed Racer began as the MSBP without the top wing. Literally. I tore the top wing off in a crash and just threw the remains of the plane into the air to see what it could do.
I'll admit I've sort got the speed bug with this thing. It's pretty darn exhilarating when it buzzes past as fast you can turn your head. It's still just a Mini Scout with an F-pack. Slightly modified a bit.
