I built this upscale Astron Ranger as a fraternal twin t' me similarly upscaled Big Bertha.  I tried t' keep this as true t' t' Ranger as possible, though t' BT80 sized elliptical cone isn't quite long enough.  Still, it separates in t' middle (with dual-chute recovery) with t' same proportions as t' original, and has a triple 24mm cluster t' lift it.  Rocksim tells me that 3x E12-8 motors will lift it nearly 1800 feet, but it'll be easier t' track on 3x C11-5s, matey, at a little under 500'.  T' design uses a baffle t' protect t' chutes, a balsa version o' t' -80BB cone and 1/8" papered balsa fins with epoxy fillets.  Finished in t' late Damon-style yellow/black stripe with red cone and a white fin graphics, ya bilge rat, thanks t' Excelsior decals.
