my new plane that I finally completed. Got to get it in the air and see if will take flight. I took the typical fish wing and put the edges down like a duck flying in for landing, I wanted to see if it was possible for a scratch build to fly like that. I don’t know if I want to put wheels on it because of the body shape, I may need a lot of take off space so, I will hand launch it and it should be ok in flight. I also made it a tail steered plane. Wish me luck because I don’t know if this will fly but, I think it should.

Any pictures ?

Hi Jim ... I was wondering that !!
I'll fly anything if I can launch it ! Youtube : solentlifeuk

Very unusual plane,good luck with it.

The pictures have now appeared on your first post. 

I second what Jimbo said. It looks like it will be a handful 🙂 good Luck.

mmmm .... I think you will have terrible time with pitch control ......... the tail moment arm is far too short ... 

But I'm probably wrong .... I wish all the luck.

check your cofg and lateral weight distribution (doesnt roll one around the longtitudinal axis)
glide test /motor glide test then if all good go for it i prefer long grass for test flights/glide trials
at the end of the day its just foam board 
good luck

Needless to say the Thunderhawk did crash, it was very unstable. Its always fun to create it and see if it flies. It looked cook when  I built it but, didn't go a planned. Back to the drawing board. Going back to the drawing bard and trying to design another plane. Im calling it the "Thunderfish". the reason is why is, my fish plane is VERY stable and its a slow flyer. So, Im going to based my planes from now on off the fish but tweak it a bit to give it different shape and have the same stable wing design. follow up soon for pics and flight.

Try to avoid every sci-fi designers and 6 years love of Anhedral wings. They are the opposite of dihedral so they are very unstable.
If you look closely at a duck landing when their wings are in the anhedral position which act as a parachute and air brakes. Their whole body is moving to compensate. Their wings, feet, tail and head moves to control what is an unstable position.
Usually the only time a plane has anhedral, is if the wing is high mounted or if the wing has dihedral and the anhedral tips prevent it from dutch rolling.
I`m not sure why the TSR2 had anhedral tips but the German He 162 Volksjager  had them nicknamed Lippisch ears after Alexander Lippisch the man that designed them to prevent the He 162 from dutch rolling.

I used anhedral tips on a flying wing that had a dihedral main wing so that I could fly the plane without having vertical stabilizers.
It was a very stable plane and I could fly it hands off for long periods.
Wot, no Depron?

For many years Russian Commercial aircraft followed the Anhedral path ... 

It led to an old airline joke ... 

When you look at an Iluyshin standing on the ground - you can almost hear it saying ... Oh *** do I HAVE to fly again ???

Its only later with co-operation with Western Aircraft manufacturers and Russian ideas to compete in the market - that Dihedral became the norm as in the Sukhoi Superjet.

Just saw this video, looks kinda similar and I was surprised when it flew so well. I don't think he's using active flight stabilization so I'm guessing the full flying tails simply have more control authority.

It`s a multirotor with all the whistles and bells to fly it😃

He actually flies it first without any of the multirotor stuff, just 2 pusher motors

I think it was Mentor Pilot on youtube who told me that big Russian planes like the AN-225 have Anhedral because the top-loaded wing would have a really hard time rolling the extreme weight underneath it if flat. The Russian planes were so heavy they needed lots of wheels, which demanded a top wing, all together making for a super-heavy hang-glider. Anhedral was the only way to comfortably control it.

Now this little star fighter, if balanced correctly is going to be very, very twitchy, it's tight profile means it's going to need minimal force to roll and pitch. If you find you have to wrestle with the sticks to get it to go where you want, a larger set of those front canards should slow the manoeuvrability down for you. A slight dihedral and actuation of those canards might even turn this thing into quite the capable spaceship.
