Lightbulb New-Old Design: Angel Express Mk III & IV

I finally got around to pulling this design out of the "Abby Normal" Rocksim folder and give it a needed workover with R9. The original file was unstable in R8. After reworking this design I realized that in order for an single 18mm to work it had to go on a severe diet. After conciderable wieght and drag loss, sorry Jay those Ping Pong Balls had to go, I have an design that still look somewhat like the original and yet preforms well on an single 18mm motor and I call it the Angel Express Mk III.

In order to keep this design in its more original form I needed more power and used an dual 18mm motor mount. Angel Express Mk IV also needed more length and more aft drag to be stable with the dual 18mm motors. Niether design has been built yet.

Enjoy and Thanks Again, JP
