Very nice dear blackkite!!!Thank you!!

 

[ArgyrisGiannetakis]

Some progress!

Wow thanks. Amazing flight!! Looks like real aircraft flight demonstration.
We can see rapid nose down at front wing stall when mid air low speed high angle of attack flight.

Some new progress!

Electric airplane!! It is wonderful accuracy.
I can't stop imaging jet powered model.

 

[blackkite]

Hi AG! How about your amazing Shinden?

 

[ArgyrisGiannetakis]

Hello !Sorry for delay.I'm near to start tests!

Thanks for the update, really looks great and I'm waiting for the first photos/videos
of the maiden flight !

Electric airplane!! It is wonderful accuracy.
I can't stop imaging jet powered model.

Don't know about Greece, but even with piston engined models, it's a bit difficult today
to find a place to fly them, not to mention with jet powered ones !
Although somewhat missing the "real sound", electric power multiplies the number of
available RC airfields in more densely populated areas.

 

[blackkite]

Wonderful news! What a beautiful model it is! Moving parts are excellent.Good luck to you.

:-[Hello, here is Hartmut again with some news about Josefs Shinden, not really good ones. See the following URL:

https://www.youtube.com/watch?v=Yv_vAxDFQ3Y&list=UUrQO1hZqKQWVoYD_6NjtcBQ

After successful test flights with the styrodur Shinden (half size) Joseph modified his large Shinden with the same settings.

The test flight failed because the side thrust of the engine did not occur to the correct side, the model side sliped to the right). Furthermore, Josef did not correct the side slip by using the rudders.
In addition, Josef has added some elevator function with the ailerons to support the Canard. He is using an aileron system ‘Frise’ where their leading edges at upward deflection rises downwards from the wings underside, sticking out to support the rudder effect in turning flight. The admixing as elevators both lower edges of course slow the airflow under the wings, which lift is anyway already weakened by the landing gear openings and legs. The speed also was not increasing by that as Joseph gave a little more elevator because of the forest. Thus, the wrong side thrust was increasing more and more so that the side slide angle grow bigger andbigger, until then the strong side airstream turned the model. Thus, the speed was quite gone now and the Shinden crashed.
Joseph had at this time the feeling that the engine was not running at peak performance, he didn’t measure the revolutions of the engine again before the flight.
By a big chance the model crashed pretty much on the nose, this cushioned most of the impact. The fuselage nose was pretty smashed, the nose landing gear and right hand main landing gear were badly bent; the right hand vertical stabilizer was broken.
Meanwhile Josef has repaired his large Shinden, he is just waiting for the repaired landing gears.
Josef corrected the side thrust of the engine on his Styro-Shinden to zero and the engine down thrust to minus 2.5 degrees (Spinner upwards). The model now flies much better than ever before.
Regards, Hartmut

It was really good to restore the body.
A next flight will surely be successful.
Do your best, Joseph.

Better luck for the next time, such accidents are really a pity, but not always
avoidable, as the "real world of aviation" shows, too. :-\
I'm just wondering, if it wouldn't be recommendable for example just to fit a
kind of provisional landing gear, more primitive, not retractable but more sturdy
and maybe fitted with predetermined breaking points to safeguard the wing and
fuselage structure ? Saw something like that on a big scale helicopter model and
it looked somewhat strange, but as the owner told me, made test flying easier
and safer for the structural parts.

 

[blackkite]

Hi! Normal shape aircraft is easy to fly even sea plane.

[ArgyrisGiannetakis]

Yes dear blackkite ,Hartmut send me also the same e-mail!I'm sorry for his bad maiden but I fortunately the damage was small and will try again with better flight !!I have so much trust to Josef!He is GREAT BUILDER AND PILOT!

 

[blackkite]

I have so much trust to Josef!He is GREAT BUILDER AND PILOT!

Yes same as you. I respect all RC modellers and RC model pilots very much.

 

[ArgyrisGiannetakis]

START TEST!

[blackkite]

Congratulations on completion of your super model!
This model is precise and intrepid.
Moreover, this model is large and beautiful.
It is worthy more than enough also as an exhibition model.
It is an ultimate model truly.
It is not believed in Greece far away from Japan that such a model was born.
Please carry out an examination prior enough, also have confidence and greet the first flight.
I am praying for a success of the first flight.

 

[Jemiba]

Good luck and all the best for the maiden flight !

 

[ArgyrisGiannetakis]

Thank you very much!
I made also some new test runs!I have to finish only the last cg balance.

[Grey Havoc]

START TEST!

Is that a trainee feline test pilot I see there? ;D

 

[blackkite]

Hi AG! Very exciting movie. I feel that I myself became a pilot of Shinden completely.

 

[hartmutbehrendt]

Hello Argyris, on this place again, all the best for your first flight!!!! Regards, Hartmut and Josef

 

[ArgyrisGiannetakis]

Dear Blackkite hello.I have some news , I made some new test runs!The shinden looks like he can fly!xaxa !I'm near to maiden flight.I hope you like it!

[Jemiba]

Looks like the nose wheel leg collapsed during the last hop ? All the best, that
this won't happen again and especially not during the hopefully succesful maiden flight !

 

[blackkite]

Wow AG!! Thanks for good video and news.
