Nice 2d. I whould like to see V tail with single EDF I think whould be faster. PS like your wing & tail fin is this box fuse

I would say , take the design and build it like you want it. And see what is faster .
I prefer to have the thrustline in line whit the wing . Making it whit single edf, i do not know how it needs to look like, do you have ideas? (Think about the thrustline).

The fuse is a box. Whit that the fuse will be smaller than a round fuse is, when putting in 2x 4s1p lipo

Just looked for a lot of minutes to the side view, and saw that it needs to be changed. The fuse height can be smaller. There is a lot of air around the lipo`s, that needs to be changed.
Back to the drawing board

and the design in 3D.
I didn't do the wing, stab and elevator in profile, just flat. The main reason it is in 3D, is to look how the space in the fuse is. At the moment i don't know if i will make the fuse smaller. There still needs to be some formers in the fuse for strenght and to give the fuse his shape. When making the fuse smaller i think the problem will be to get the lipo's in and also the wires. I made the mistake whit the uriah, that the lipo wherefor i build it, didn't fit. Ok, the lipo did fit, but not whit the wires on it. And till now there aren't wireless lipo's

3d and EDF, some scale

I've had a design on posterboard for a year or so and it seems like I have the fan combo needed in my Phazer. It produces very high efflux and the Phazer is extremely fast so I hope this one will be to. It's hotliner esqe with a side intake design, I'll post a pic after I rough the fuse out. 60mm on 6s 2200 is the plan

Good progress! I do see some similaritys of my concept

In theory you could place 1 fan in the centre and a fuse along the side (like a simplified Rutan Ares). That might be a good option to create good batterie space for high power setup (for a single fan jet) and good space for hardware.
With some creativity you can increase wing and elev mounting strenght as well.

I often noted closing a bifurcated exhaust on one side to gain intake efficiency on a Pyranha or Sniper like Ares.

Just a thought at Luft46 there is a jet designed like this but cannot find the model in short time notice.

I think you mean bifurcated intake, not exhaust?

So here's where all you speed freeks are hanging out. I've got some stuff in the works. Just need some new motivation. Some fellow crazies will do the trick.

Lee, I consider you one of the definitive speed freaks. I'm hoping my design hits 180 plus

I have a couple ideas kickin around one being an asymmetrical design.
