Obscure subject, but worthy (if you're weird).

Does anyone happen to have information on this?  There were about two dozen built in the middle of WW II, and according to Wikipedia there are no survining examples.  I'd love it if someone knew of a book (even if it's not in English) that was chock full of pictures that could be used as scale documentation.

Not sure how much help this will be but Al Lidberg-

has been selling a Rubber Scale version for many years.
Don't know what docs you get if any.

The BV-141 has a bit of a following among plastic scale modelers. Here's a link to a recently published book specifically on the aircraft.
http://www.valiant-wings.co.uk/airframe-detail-26-c.asp. Lots of pictures, drawings, including 1/48 plans and colors. I have their Westland Whirlwind book and it is excellent.

I have the Lidberg kit and it's killing me. The wing and tail almost built themselves, and the boom looks like it'll be no trouble, but the pod's turning out to be impossible (for me, anyway). The sides are 1/16 sheet that I can't contort into the twists and curls that they have to assume to fit the formers. I think that eventually the sides will get built up out of 1/16 square and it'll come out okay, and maybe a bit lighter to boot.

Hey Art:  This may add an unacceptable amount of weight for rubber powered scale, but how about finding the thinnest clear ABS that you can and vacuum forming the whole thing.  Then paint a framework on it and stick it to the wing.

I'd be very tempted to do just that on a CL scale model, but I can get away with a lot more weight.

This is an excellent idea, and it can be done pretty lightly.

Al Lidberg's plans show a very lightly built balsa frame for the cockpit pod overlaid with celluloid. There's been a few RC versions of the plane, too. Nick Ziroli did one for MAN magazine in 1992:

Old topic, so BUMP...!

Has anyone simply cold searched on the name, or on German aircraft + B.V.- 141?
Plenty of words to be found. Some useful.

I remember a fairly detailed article in the Aeroplane, or Air Enthusiast (both UK mags) several years back; may still have the mag. Search would be time-consuming... AE went totally passenger-liner jet several years back - not my interest!

As I recall, the article discussed the why and how of the asymmetry. Engine-mount torque helped offset the wing area imbalance, which wasn't actually as great as it appeared to be. A test pilot - possibly the universal Eric "Winkle" Brown? - reported a brief flight in a  -141 captured by Allied 'researchers' early after WW2. Except for 'the visuals,' he said it felt quite 'normal.' (!)

BTW, back about 1970, I was stationed at Boston, MA. Several modelers around there were able to use the concourse in nearby Dedham Mall for an hour or so after closing as often as once a week for some indoor rubber FF flying. The HVAC made film model survival unlikely, but HLG and Peanuts (were there Bostonians back then?) did well. A prosperous hobby shop tenant there helped our case.

As ever, my first devotion is glow engine CL Stunt, but I have dabbled in most other efforts. My Peck Gypsy Moth was good for a dependable 10 to 15 seconds... (different techniques required; I wasn't all THAT motivated...  Cheesy )  Also did a profile peanut BV-141! And, yes, it turned and glided into the pod. But it DID fly controllably - at least trimmably...

One of my "resources" on the BV-141 had a page-spread drawing with the span diagonal. Just the right size! Best duration about like the Peck Moth. I mean, hey, I fly ukie! I was great fun anyway!

As a total aside does anyone remember Smokey Yunick's capsule car?  It had the driver sitting in a pod attached to the inside of the body. That design was inspired by the 141 and the lower drag that was supposed to result.  The second result for this weird configuration was it was supposed to be turbine powered.  This was several years before the Granatelli turbine. He was a true innovator and mechanical genius but did have the morals of an alley cat.

Thanks Steve!

Thinking about that indoor FF profile... Just realized that the prop needed to turn clockwise (seen from front) to use the same torque effect as the original. Were there ever any left-hand Northern Pacific or Sig plastic prop and hanger sets?

Ah, well, that was only 40 years ago..
