Title: Dorastonian 190-D9
Post by: Sky9pilot on August 13, 2014, 11:39:02 PM
Roman designed a Bostang a while back and someone suggested we needed some more WWII birds to go with the Bostang.  So here's my prototype Dorastonian 190-D9 (Fw 190-D9 Dora). 

I've already found several things needed to corrected on my plans for this little jewel.  But here's some pics of the progress so far.

Thanks DaddyO...

I'm still tweaking it right now.  When I have it in better shape I'll share it here.

Cheers Tom - no pressure I don't usually start indoor flying till October/November  :)

Keep finding little areas that need tweaking on the plans before they'll be ready.  I got the bones completed today and my fixes on the prototype have added some additional weight on the nose.  Hopefully this won't be a problem.  No problem going over the minimum weight for the Bostonians with this bird.   In the next version the cowl won't be sheeted but made as an extension of the fuselage and eliminate some balsa discs in the cowl construction.

Here's the completed bones for the Dorastonian...

Got the tissue on after some challenges with the grey domestic tissue.  Here's the pictures...

A little more progress on the Dorastonian 190-D9.  Got some camo and start of markings.

More progress on the Dorastonian...

Panel lines and markings done.  Still have the canopy, exhausts & air scoop.

Lookin' good Tom - that top view reminds you how porky these Bosto's really are  ;)

Keep it up

I like it a lot - I have a half-drawn plan for a Lysandonian somewhere. tho high wing is probably cheating.

Thanks fella,

DaddyO...looks pretty porky, but as you say that's the Bostonian aspect of these babies!  ::) ;)

THB...Let's see the Lysandonian!!!! ;D ;)

Finally finished the canopy plug and made the plunge molded canopy today.  Was kinda pleased with how it came out.  I used the clear plastic tops that come with bake goods from the local supermarket. I'm using Aleene's Tacky Glue to attach the canopy.  Works pretty well. Holds the canopy and dries clear.  Here's a couple of pics.

Completed the panel lines on the canopy with grey tissue.  The Dorastonian is complete.  I don't compete so no gear on this one but easy to add, I left mounting plates with holes in the bottom of the wing for that possibility.

Tom, I havent visited HPA for quite some time. Your Dorastonian looks great.
Did you have a chance to fly it in the meantime? I am interested in hearing if the flight pattern is similar to a Bostang.
The wings looks so tiny on these models, but somehow they fly ;D
I assume the Dorastonian also likes some power?

Roman...

Have had family visiting the last few weeks and so no modeling done for a while.  Still have a few weeks of visitors scheduled so we'll be busy with them for a while longer.  Looks like rain in the forecast as well.  I hope to get her in the air soon.  I assume she'll be like the Bostang in the flight characteristics, needing power to get those wings flying.

Tried balancing and trimming the Dorastonian the other day and have had to put too much weight on the tail to counter the prototype cowling.  I'm not pleased with this.  Way too heavy.  I've also broken the leading edge of the left wing panel in the process.  So I'm looking at a second prototype with the modified, and much lighter cowling arrangement.  Learned a lot on this one hope the second one turns out much better!

... have had to put too much weight on the tail to counter the prototype cowling.
Maybe a shorter nose (Fw 190 Astonian ?) would balance better?

Tom, sorry to hear that your Dorastonian nees some modification.
I am looking forward to see the optimised version here. The Bostang is ready for a friendly test-dogfight between Bostonians ;D
Waiting patiently for Dorastonian Nr.II to be ready!

Thanks Roman....trying to salvage some of prototype #1 for new fuselage on #2 with much lighter cowling.

Tom, any news from your Dorastonian?
Hope that you didnt abbandon the plan....

Considering that this is not an exact scale version, maybe if you moved the wing/cockpit somewhat forward on the redesign, the balance /trim might be simplified?

Greg

Thanks for the interest and suggestions fellas.

I've kinda put the Dorastonian on the back burner due to involvement in two cookups.  The Bf109E3 here on HPA and the Senator on S&T.  I'll get back to the Dorastonian a bit later.  Kinda lost the mojo on it right now.  The new fuselage will be much lighter due to a highly simplified cowling arrangement.  At least it looks that way in the CAD redraw.  We'll see before the year is out.  You know the old adage, "So many planes, so little time!"

Tom, thanks for the update.
Looking forward to see more of it when you are in the Bostonian mood again.
