Looks like a copycat Cub ,with a Pobjoy radial..

skytrain10 2nd Nov 2011 11:37

No connection with the Cub that I'm aware of. Not a Pobjoy engine.

Good afternoon Ken,

Is that a Brochet MB-70 ??

I'll have to ask for an Open House if it is; I'm just having a lunch break, but then it's back to the workshop.

Edit: just managed to cobble a challenge together, but my monitoring might be a little sporadic, up to you!

Is that a Brochet MB-70 ??
It is indeed Trevor. Well done:ok:

Brochet MB-70 - Tourisme - Un sicle d'aviation franaise

SincoTC has control...go for it...

SincoTC 2nd Nov 2011 14:08

Thanks Ken,

Good timing; just off now, will check back every half hour or so!

Hi Trevor! A long-endurance machine? For surveillance? American? RR

Edit: actually I think its more like a motor-glider? European? Cezech, perhaps?

SincoTC 2nd Nov 2011 15:06

Hi Martin,

Not for surveillance! Endurance yes! It was built as a trainer and to set the distance record for sport aircraft of 500 - 1000 kg (flightweight)

Not American

Seen your edit: It was a motor-glider, but not Czech, further East :)

Edit2:

Just noticed that for some reason, the image I posted still shows a dimension arrow and leader lines showing width over the tailplane, I did obliterate these, deleted the original image from Photobucket and then uploaded the new version before I posted it here, but it's still there (although it doesn't show up in the PB preview) :ugh:

A teensy clue. In case you haven't noticed, there's a reason for no front view that may help!!

Ridge Runner 2nd Nov 2011 16:18

I guessed that was because of the V-tail!

Edit: Argus engine?

SincoTC 2nd Nov 2011 16:42

Regarding the tail, you guess correctly, but it's not an Argus!

Aircooled inline engine, not German, it switched manufacturer at about the same time as this aircraft was built.

Edit: Clue time!

The engine was not built in the same country as the airframe and the airframe's designers took as a starting point someone else's existing and agile sailplane that itself went on to established a world speed record.

Evening (or should I say morning) Trevor. Not in my glider/motor-glider book. I notice you didn't answer Martin's question about it being European.....so Russian maybe? Is that a Walter engine?

Karlark 3rd Nov 2011 02:53

I believe you are right that it is Russian, Ken.

It appears to be a: Мотопланер "РИИГА-2" ("Рекорд")

Edit in English: Powered glider "RIIGA-2" (the "Record")

SincoTC 3rd Nov 2011 06:25

Yes Ken, it is Russian, not sure if the engine, an M-332 was built by Walter as the manufacturing rights were transferred to Avia in 1964 and the aircraft was constructed in the period '63-65.

Karlark is spot on, it is the RIIGA-2 "Record"; based on the Antonov A-13 aerobatic glider, great detective work :D:D!!

Karlark has requested an Open House :ok:

Boulton Paul Sidestrand/Overstrand?

Noyade 3rd Nov 2011 08:23

Getting a lot of "Database Error" alerts, so I better be quick.

Your control Sabredog! The Sidestrand. :ok:

sabredog 3rd Nov 2011 09:36

Hi,
first thought it could be a Fieseler Storch
or may be an Aero L 60 Brigadyr?
Greetings Flying Bull



Ridge Runner 3rd Nov 2011 12:42

Serb/Yugoslavian?

Edit: it looks like an all-moving tail?
