Indoor / The Imp - EPP Indoor Combat Plane
« on: January 05, 2011, 16:38:57 PM »
If you were at the CMAC Indoor fly-in at Middleton last October you might have seen the little orange EPP delta I was flying. I designed it with indoor combat, pylon racing and general messing about in mind. It flew well but needed some tweaking to make it as crash-proof and practical as I wanted.
I got time to sort it out and do some testing over Christmas and now it's working very well. I think I'll call it the Imp but any better suggestions will be gratefully considered :?: !
We had 4 of them in the air together on Monday for some combat (with and without streamers) and we're all agreed it's great fun! Lots of collisions, lots of streamer cuts, lots of fun and no significant damage (nicks from enemy props is about all we've seen).
It's built entirely from 6mm EPP (grade 20L – this is the soft stuff) and a little 3x0.5mm carbon strip. The prop's in the middle and it's got a big, blunt, bouncy nose.
It's virtually immune to head on collisions with walls, floors and roof beams (we've tested this several times now!). There's no landing gear or other breakable bits sticking out (but it can still take off easily from a smooth floor due to the new fuselage shape).
I'll post some photos in a couple of hours and maybe some video if I have anything suitable on the camera. I lost the CAD file for the latest version :!: so I'll need to re-draw it before producing a plan and then I'll post it here.
Technical specs, photos and plans coming soon!

This is my excuse for not making progress on the Index 4......
