From Le Fana 388,

Very nice. Once I came across only one picture which is labeled as AC-11. Clearly visible is different engine (when compared to MC-101)

Found some photos of the unfinished AC-21 in "Revista de Historia Aeronautica" No. 41





And a detail of the tail nozzle similar to that in the AC-14



For those who are interested and are able to read Spanish, you can download the magazine on the homepage of the Spanish ministry of defence:

https://publicaciones.defensa.gob.es/media/downloadable/files/links/a/e/aeroplano_41.pdf

Details of the AC-21 begin at page 112.

I think that,I have most of Flaps issues,what was this ?.

In the book History of the helicopter as told by its pioneers 1907-1956 by Jean Boulet on page 141 you can find a picture of the MC-101 equipped with 135 HP Lycoming engine and renamed to AC-11.

I was looking for any other picture of AC-11 (other to one posted previously) but with no luck on the internet search. So here you are Internet

Photo caption: André Ondre at Madrid, in front of the MC 101 which was renamed AC 11

I have no info about that, I'm sorry Hesham

 

[Antonio]

André Ondre in Madrit

What is "Madrit"?

 

[persil]

What is "Madrit"?

I guess it meant the airport: https://en.wikipedia.org/wiki/Madrid–Barajas_Airport

Thanks, then it's just a typo

Can you see if you have one from August 1961?

 

[Justo Miranda]

Thanks, then it's just a typo

In the eighties the Cuatro Vientos Air Museum commissioned me to draw all the planes they had at that time, I remember working with two Aerotécnica helicopters, one of them with the NOTAR system.

They were quite detailed scale drawings but I have not been able to contact someone who keeps a copy, it would be interesting to be able to exhibit them here.

 

[hesham]

What about the missing numbers, AC 16,17,18 & 19 ?!.
