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, me hearties, but it'll be easier t' track on 3x C11-5s, 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, thanks t' Excelsior decals.
