Any update for the plans on this one?

Well, we just got the Rascal Racer in optimization. The Goshark project is still on hold. We've tested different wings: FT folded in scale, KFm2 and FT folded with a wingspan of 70mm. The most stable wing is the FT folded wing with 70mm wingspan, but this is not scale! In addition, we have only tested the 50 mm EDF units from Hobbyking so far. The 50mm EDF unit from FMS is currently not available. As soon as we have this EDF unit, this project continues - i promise! After all, i have the decals ready! I could put together a BETA plan for you with the latest parts, if you don't want to wait.

After receiving my 50mm 4s FMS EDF unit, I started this project all over again. The basis for this are these three views of the T-45 Goshawk:
I built the model out of Flite Test Water-Resistant Foam Board and sanded it:
Then I sprayed it with white paint and applied hand-cut decals made of self-adhesive foil. Here is the result:
It's even got a rudder! The wingspan is 660 mm (25.98 in).
Here are a few weight indications:

Here are a few weight indications:
- Without battery: 388 g (13.69 oz)
- With 850mAh 4s battery: 484 g (17.07 oz)
- With a 2200mAh 4s battery: 641 g (22.61 oz)
That looks great!

I hope it flies as well as it looks!
V0.3:
View attachment 93869
I replaced the two 5g servos with one 9g servo and a 2mm linkage stopper.

I have already prepared some decals:

In the search for the decals I found this awesome "Goshawk Ball" video:
V0.3 had enough thrust with the Hobbyking 50mm Alloy EDF V2 4200kv.
Unfortunately, it got strong side wind and was not interceptable. The result does not look good.

V0.4:
I am currently building V0.4. The rear part is no longer so angular and the air intakes are closer to the original.

Now it needs a new canopy and a wing, then it goes to the next test flight.
I will enlarge the wingspan from 610 to 700mm, let's see how it flies with it.

Could you please send me the v0.4 plan, I really like your design. I want to try to change to push version.
thanks,

If I remember correctly when I built one of these...V3 I think, it flew amazingly until I went inverted....I hope it flies as well as it looks!

Look great! Can I have the plan? I'll try to make in 70mm EDF.

What a cool plane. I hope the plans get published.
I've been reading up on EDF design because I'm scratch building one also. One thing you might consider is intake size. It looks adequate, but you can test a "cheater" hole on the belly in front of the edf to see if it is starving for air on the intake side.
My ideal for FT would be a new edf design like yours that is simpler to scratch build than the Viggen. I downloaded the plans and beside the fact that the cut lines didn't line up it was so complicated I decided it would be easier to design from scratch. Also Banggood has a 64mm 3s unit for $15! If it works half decent that would make a perfect cheap starter edf.
Keep us updated, I love your design - simple yet elegant.
