4F-51 Fat, Flat, Floppy, Foamy
Been playing with cartoon scale again, and wanted to do a tail-less plane for a while... So why not?
Plenty of wing area! Plenty of Power!
Used EPP sheets from www.slofly.com, and a 18"x1/8" c/f tube for a spar, but FF or Depron would work fine (Just reduce the wing slot accordingly).
24x 12 wing + 4" elevons
15t CDR, 8x4HD prop
2s830, 7.6a, 53w
9.7oz thrust, 29mph
4 channel, elevon, rudder
I love the way it flies. Much easier to fly than my IFO! Looks to be a torque-roll monster. I haven't had any still air, but early attempts show a lot of promise.
No reason we couldn't do all kinds of profiles in this fashion!
Here's a video: https://www.rcgroups.com/gallery/sho...cat=500&page=1
(Pictures show early elevons, they are 2x as wide now )
Oops, added the full size, non-tiled pdf's...
Edit, for search engine? 4f51, fat flat floppy foamie, mustang,
Edit: Added GPW's XP-39 files

No video yet, maybe tomorrow.
You can sorta see all 3 servos. I set them where I thought it would want to balance, which BTW seems like a pretty wide area for battery placement.
Right now I'm flying it with a cg at 3.75" behind the LE at the root. I'm sure that's nose heavy (23%), but it seems to handle it fine in the wind.
