Anyone ever heard of this. ratcheeroo it looks kind of along the lines of the bronco you were/are building. I think it looks neat, I have always wanted to do a high aspect ratio plane. Does anyone know if anyone has built one? It is a Burt Rutan plane, designed to fly 40 hours at 230mph. Pretty impressive if you ask me. en.wikipedia.org/wiki/Northrop_Grumman_Firebird  |

Have never seen one of those, very cool. Looks like a perfect FPV platform.

Have never seen one of those, very cool. Looks like a perfect FPV platform. I am trying to figure out what size it would need to be. Would you do a 90" wingspan with the outer wings being easily removeable? Like a 3536 motor spinning a 10x7 prop on 4s? Or maybe 60ish inches, make the 2 outer wings 1 section of DTFB (shortways) and maybe just a 2212 motor. My daughters FPV ship with one of those 2212/1400kv value hobby motors will fly all day on a 2200mah pack. |

Thinking that if you went out to 90" that those wingtips would be more than the 30" you could get out of a sheet of foamboard, and then you have to think about structure to keep those and those tail booms in place. Going smaller is going to make that process easier and probably make it a more sound structure. I think @ 60" the 2212 setup would be fine, @ 90" the 3536 setup is probably a must just because I think it would come in a bit heavy(5 possibly 6 sheets of foamboard minimum is my guess). I don't think I would do this less than 60" though, those are awful skinny wings. Very interesting build, and a pretty good challenge with the gull wing and tail booms. Very big cool factor with this one.

I have a couple ideas about the wings, some better than the others. I feel carbon rods sliding into a 3D printed structure would be a little weak.

Ya know this one is bugging me, and not in a bad way lol. My first thought was yea something 3d printed and carbon rods but yea probably weak and heavy. Wing sweep and boom tail kinda makes it weird to come up with a spar setup to support the whole thing
