Default Build thread- B1B bomber EDF

Im going try and build a B1B bomber and hide an EDF.
I cut out the nose piece with cnc foam cutter. cut it with 3 different profiles from 3 different sides. Then I sanded out some edges to give them radius.
Im designing this as I go.
I am going to work on the tail section tonight.

I have a couple of projects going on, just thought I would add another.

Looks pretty close so far.

cncfoam how did that P-38 you were doin work out? I lost track of the thread back when you were in the planing and disscusion stage.You can copy Steve Shumates design for a swing wing spar box and make the wings swing easily.It's been done on the F-14 ,B1B and the F-111 Ardvark.Have you seen any of the efforts on this plane done by B1B Man He's done 2 that I know of as twin motor pushers?

Default p-38

I put the fx-38 on the back burner for now. Fx 38 will take a lot of cutting of different parts. I have been cutting for a guy in colorado, he keeps me pretty busy.
Im trying to keep this B1 really simple with very few cuts but yet keep somewhat of a scale look.

I did see the B1 from the other post. Very nice.

I am going to keep this as a fixed wing. simple for now.
I just finished drawing the rear fuse parts and Im going to go cut them now.
will post later with pics.

Default Bottom view

Here are a couple of pics of the bottom side.
I cut out some long parabolic cuts so as to hide the single fan that I will use. The fan will get full air, front and back.

Default wings

Whipped out some wings.
I used naca 63412 for root and 63415 for tips.
I oversized the wings from the scale drawing. They were dinky.
As I always do, I cut the dihedral into the beds. (not shown)
the top of the wings are flat and the bottoms have dihedral.
The wings will remain in the swept forward position.

Other tidbits...The fan is rated at about 750g-950g of thrust.
26oz-33oz. I did not use the recommended motor, but the motor I am going to use should give me at least the 26oz of thrust.
I weighed all of the foam parts, what you see in the picture weighs 4 oz,
my equipment weighs about 16oz. So I have a little lee way, with weight.

send me an email at jjme @ comcast. net (put together)
we can exchange phone #'s

I have been busy with work, I need to make some changes on some parts, then I am going to make a chuck glider out of one, then build the other.
I did run the fan, I am fairly certain this fan will have plenty of power.

Just ran across this thread . Did you give up on her? Sometimes things don't come out exactly like we would like em and we shelve a project. Don't let that happen to you this would be a cool plane.
