Morning all

Good one Martin!! Elusive little bugger this, got me well and truly stumped too !!

And I thought Reg would have got it!
Wondered if that was a subtle pointer to something from Akaflieg Berlin, but if it was, I didn't find it; 'tiz similar to the the fva-18: "primitive crow" from Aachen, but that had a VW engine, wrong tail and we've had it already. A variant of the Sperling, but can't find anything, ditto the Do-25 !!

Obviously missing the killer keyword !! Maybe Glider towing or motor-glider??

Was this a little known abandoned product of one of the main manufacturers, or an early, possibly amateur attempt from the (German?) designer, who went on to produce the "well known and similar machine" for another company?

Off to work now, will try and get back later

Hi Trevor!!!

Sorry mate, none of the above. It was built and flown. I'm not sure it still exists. There is a photo and 3-view on the net. It didn't lead to anything and was built as a one-off. However, one of the designer's other machines was reasonable successful - one on the UK register - and was revolutionary in its way. Remember the STOL aspect.

I'm out today - family sickness probs - but will log in on the Blueberry later.

As I'll be out and about here's a further clue: a side-by-side, two-seater. If anyone gets it while I'm away just move on as I wouldn't want to stall the thread - it never stalls!

Good morning. Not had a chance to look recently.
Martin, is it the Zweisitziges Langsamflugzeug LF-2 Kiebitz?

If correct will have to be Open House

Morning Ken!!!!

Yes, its the LF2 Kiebitz. I think Brian was getting close! As you can see, but was related to the LF1 which was impossible to stall - hence my latest clue.
- Institut für Flugzeugbau und Leichtbau (IFL)

Ken has declared OPEN HOUSE

RR

Edit: where did Brian's post go???????????

Great challenge Martin. I found Prof. Ing. Hermann Winter's LF1 but just could not find the follow on.
