Wow! That looks great!
Are you sure the V-stabs are going to be big enough?
Wow! That looks great!
that was my next question LOL. yeah they gotta get biggerWow! That looks great!

SLEEK! I'll be following.no, i will go for a American modern prototype.... The Privateer. First testflight 2018
That's nice. Did you see the one called "Seahorse"?
I uh... ok.
Hey I can't get over that airfoil - I'll be planning on copying that one of these days!
Absolutely! So here is where it gets interesting I think, I have these motors from a quad I used to have but not sure how to go about utilizing them for this project. Any insight , opinion on this would be greatly appreciatedHey I can't get over that airfoil - I'll be planning on copying that one of these days!
Love it! Electric Bugaloo love the nameThis is so perfect, the pilot is also German stig
It says it in German on the other side.Love it! Electric Bugaloo love the name
Made a start on the Sea Hawk fuselage centre section "half shell" built over the plan.
duct assembly to be inserted exactly half way in!

Now to add the other half of the formers and do some more planking.
skymaster
My favoured construction method for a fuselage in sheet foam is by planking to create a half shell monocoque.
In this case (the fuselage for a Cessna Skymaster!) the 'half' formers are positioned over the plan and the planking (in this case 3 mm Depron) was gradually completed.

Once the half shell is complete it is rigid enough to be lifted from the plan and the other side of the formers added.

This is then planked to eventually give a complete fuselage.

The fuselage has no internal structure other than somewhere to put the battery & electrics relying entirely on the skin for strength and rigidity.
Not the easiest thing to do (the more you do the better you get at it) but it does result in about the lightest possible structure. Note most of the planks run the full length of the fuselage so the glue joints are not in tension where glue tends to be weakest.
The completed Cessna.

Everything is 3 mm Depron. The only balsa is in the wing spar and the short wing struts. Light so easy to hand launch and it belly lands just as well.
I intend to use the same sort of construction for the Sea Hawk but using 5 mm XPS foam sheet.
Ive got some brushed motors id like to use too. This esc is kinda big but it could probly run 2 motors at once and you could double it and have all 4 motors from the quad on your wing for differential thrust. Other than that just about everything brushed seems to be incorporated into reciever unit.Absolutely!

Maybe someone who understands transistors could help me.
Leaded50You dont have any posibillity to mount the EDF more to rear? That way you could maked better intake direction on the airintakes. Thats reason for you loosing close to 50% of effect... or more. You will not gain much by a "ram-air" effect here either.
