Doppelpfeil 1.0 Maiden (1 min 45 sec)


She's a handful..working on Doppelpfeil 2.0.......

flew her 5 times successfully..it was that "Oh let's put her up one more time" that killed her....got her in the sun, lost orientation, and she went in hard....BUT..the foam board crumpled like the front of a Mercedes, saving all the electrics........

This is for all the guys on RCAAA......you know who you are !

I've decided to try to build a 3D-ish foamie......so I stole the stuff I liked from 4-5 ARF's and came up with this....takes (2) sheets of 3/16" Elmers board and a 2 liter bottle for the canopy.....I'll revise and annotate once I build her, but you guys get the idea......As always, drawings are on 36x48 paper.. foam board blanks are 40x30.

I did a box fuse because I don't like batteries, ESC's, and Receivers flopping around in the wind !

This ain't Dollar Tree foam !
