Hi Marcogrifo,
thanks very much indeed for your continued assistance in this rather difficult task.
Now, the Republic XP/72 is already included in my original list (30th line), whilst both the Convair 117XP5Y-1 and the Kawanishi N1K1 15 Shi prototype will be reflected in the new list I'm preparing.
By the way the prototype picture of the Kawanishi is extremely interesting and it is worth while to remark that this japanese aircraft was originally tested with a powerful 1460HP engine MK4D Kasei 14 driving contrarotating props to reduce torque.
During production however the contrarotating props were dropped for the sake of simplicity and the plane became the Kyofu.

I think the Convair 117 XP5Y-1 became the 'R3Y Tradewind' as per below :-

VERY interesting paper on Contra Rotating Propellers

Yes Cromwell youìre right but notwithstanding the similarities they are still two different aircrafts and not just a denomination change...

Hi Cromwell,
I'll check very very carefully all the links of your yesterday's posts #43 and 44.
However it is my intention to include in my final list only the aircrafts with contrarotating props flown, tested (also of course prototypes) or mock-ups excluding projects which didn't materialize and paper planes.
Cheers

...on second thought, Marcogrifo, I don't think that the Arado AR/64/C was powered by contrarotating props. I think what we have on your pic is a four bladed propeller .
Please also have a look at the following link:
Arado Ar 64.

On the other hand it would be interesting to have a second opinion.

Is that not GOOD news ?? You now have TWO more aircraft to add to the list

I do believe the operational Tradewind had Contra Props - but tell me if I am wrong

Check this from Arado Ar 64 - Wikipedia, the free encyclopedia

" The two differed as the 64d had a revised undercarriage and a four-blade propeller and the 64e had a two-blade propeller attached to a direct-drive version of the Jupiter VI radial engine. "

There were a few Spitfire Mk 21's (and 22's, possibly?) fitted with contra-props, using the Griffon 85.
I've only just become aware of these (the 21's) via a book I'm currently reading.
Prior to this I had dismissed the Shackleton engined Spit referred to earlier in this thread as total B.S.
I'll try to scan a photo from the book referred to - keep up the good work, Carson '34... your book should be a beauty!

As promised. From RAF 41 squadron 1947. If anyone can tell me more about Mk 22's with c-r props (or even better, a photograph!) please post same here. By the way: the Spit getting around with the Shackleton installation (other insert) is evidently a Mk19, so it IS in a sense, a bit of B.S. - but still rather impressive ...! Note that the 21 has the extra covering for the wheels, (and larger oil/intercooler boxes?).

Hi Siznaudin, welcome to the "contrarotating props" thread!
Thanks for the information and pics, no I'm not trying to write a book on this subject but merely my object is to compile a listing as complete as possible of such like aircrafts actually flown and/or tested.
I'm leaving out of this list the so called projects and "paper planes".
Say hello for me to Adelaide (a city I love)!

Hi carson,
sorry for the mistake, I think you're right
Seems like they put two two-bladed props together in order to have a four-blade prop

Cheers

Was this one mentioned already? Tempest III:

Hi Marcel,
thanks for joining the thread and for the submitted pic.
Yes it is included in my list with her new denomination, i, Hawker MkI "Fury" (registration LA610)
equipped with a Rolls Royce Griffon engine 85 and contrarotating props. It flew in 1944.
Cheers
