The Bv 148, Dr Vogt's 'conventional' version of the Bv 141 - DONE

[Wardukw]

Oh a feeling i am about to know all to well myself in the near future ...if everything goes to plan

See, no booms, no asymmetry and only one engine. 

The Bv-148Z was different, see my twin-boom topic https://www.whatifmodellers.com/index.php?topic=20326.6255

You could go for twin fin and out a proper tail turret there.  Sure I have a resin back end somewhere that could be repurposed.  If not, the mould may lurk in a drawer.

I may have to scrounge a nose glazing if you have one spare?

I have, unless the one in use cracks when I saw bit out of it. But I'm confident it'll be OK.

Interesting... somewhere in this thing's development history, there has to be a horribly comic accident in which the cockpit pod comes un-fastened and starts rotating with the blades...

My thought on a twin-engined Bv 141 was always to put a pusher engine on the back of the cockpit pod. It'd need to be water-cooled, of course, and the other one should probably match it, but that's nothing that a pair of sacrificial Fw 190Ds couldn't provide...

Don't think that hasn't occurred to me while trying to figure out how to model it with the props being able to rotate! 

But I think I've figured it out.............

I believe that this phenomenon is known as either "gerbilling"  or "hamster wheeling"    and results in a terminally dizzy pilot and  vastly amused onlookers (from a safe distance).  Air brakes deployed from either side of the cockpit pod might possibly save the day.   Hopefully the potential incident happened during ground running.

There's a relatively easy way to do it, but then you lose the ability to stop one engine...

[PR19_Kit]

It may only have one engine eventually, I haven't decided yet.

It may only have one engine eventually, I haven't decided yet.

In that case, you could do it like this:

A wide-diameter, rigid, fixed tube joins the front and back fuselages. The props rotate around the tube.

The engine drives the rear prop via an offset shaft and a ring gear on the back of the prop.

The rear prop has another ring gear on the front of it, which drives a set of pinions on fixed stub axles located around the tube.

The pinions drive another ring gear on the back of the front prop.

Lubrication and sealing are 'interesting'...

[PR19_Kit]

That's pretty much how I was thinking of doing it, yes. 

[PR19_Kit]

The easier port wing is done structurally, and the landing gear retains the same track as the Bv 141. 

Some PSR to do obviously, and I may file off ALL the original rivets and scribe some panel lines, much though I detest doing that.  My trusty razor saw and big flat file are putting in some sterling work on this job, I can tell you!

You cannot view this attachment.

The port wing still has some work to be done, but the work is pretty much the same, just with more parts needed for the root extension.

The fuselage work awaits some plastic tubing to go further, I don't have the right size to hand at the mo.

The protrusions just in front of the aileron are horn balances and should be separate.  This should help::

[PR19_Kit]

Yeah, I figured as much, the ones on the tailplane will be missing on one side though, as the added half will be upside down. 

That's a very good pic, thanks. A pity they didn't take it from a bit further back, and they'd have got all the wings in too.

[Wardukw]

That's looking great Kit...some nice plastic surgery that 👍 😀
