Monino Museum MAI-63? tailless glider

[Retrofit]

On the following forum ( http://www.reaa.ru/cgi-bin/yabb/YaBB.pl?num=1124882379/60) on the Monino Air Force Museum's restoration works, are presented several photos of a tailless glider airframe referenced as MAI-63,
but the photo and drawing of the original MAI-63 glider (from the book "Letatyelnyye Apparaty MAI" by Makarov) show a quite different wing shape.

Any clue about the identity of this airframe and its history?

Thanks in advance,

The new photos sure look like the same plane shown in the old photo.

My dear Retrofit,


we opened a topic for MAI aircraft with MAI-63 before;

I know my dear Hesham,
But I am still not sure about the airframe identity: i.e. different center body's shape, external wing sections with an unregular trailing edge, different wing tips with a marked dihedral.
"Only" the wing's strait leading edge sweep and the wing fences are similar.
It seems to be a mix between the MAI-63 and the MAI-68.
Or perhaps it is the modified MAI-63M but without its engine system.
Needs to be confirmed.

If it is the case, this post could indeed be merged with the one mentioned by Hesham.
