Hi
I would like to share some pictures of my Bostang B51. At the weekend, I was able to improve the trimming and take some first flight shots.
Since I fly mostly outdoor, I remove the landing gear to avoid damage from the langing in the grass. Paper tubes are in the wing and fuselage to take the landing gear if needed.
Until now, only flights without gear have been made. Looking forward to see it with the gear on....
Best Regards Roman

CUTE!

As it is not at all likely that any means of suspending the effect of air-resistance can ever be devised, a flying-machine must always be slow and cumbersome. . . . But as a means of amusement, the idea of aerial travel has great promise.

I like it!

"Scale" aircraft can be impressive but sometimes I feel they restrict the creativity of the designer.

... visiting other sites, I pay attention when someone mentions "cartoon scale" or "what if scale" ...  Grin

Wordgui, thanks. I like your peanut plans. Hope to build one soon. Haven't decided which one Wink

skootertrash47, I have already uploaded the plan to the builders' plan gallery. It has to be reviewed first...
If someone builds it, please post pics. I am looking forward to see it Smiley

pertime, I like "what if - scale" => nearly endless possibilities Smiley

Best regards Roman

What a great plane! The Bostang is awesome!
Makes me wish I knew a little more, actually a lot more about designing.

Hello Roman.

I was wondering if you might give me some tips on how you turned your spinner?

Thanks,  Skip.

DLPHOTOG, just try it. If I remember well, there was a thread on SFA (or was it here on HPA?) about how to start drawing and designing a plane from a 3-view. Unfortunately it was not realy finished, but enough to start from. It's easier than you think.

Caley, thanks Smiley

CeeGee, I documented the progress in the Koutny cookup http://www.hippocketaeronautics.com/hpa_forum/index.php?topic=2132.390 look at post#414. Hope that helps. There is also an article in the Builders Plan Gallery on HPA.

Zoe's website has a scanned copy of Flying Scale Models by Ron Moulton which explains how to scale up a three view for modelling (plus a lot more hints and tips as well)

I've the actual book here (I bought it years ago when it was first published) - it is very detailed on how to do things and I still refer to it ;

...Makes me wish I knew a little more, actually a lot more about designing....

Gor it DL!

As Roman said, it doesn't have to be over complicated - there are a few basic rules of thumb to follow that should get you to a flyable model... All you need is some method of drawing, either CAD or on paper (my preference.)

Why not start a development thread and chuck a few ideas out there? There's plenty of people who would find that interesting and who'd be there to help...

Nice work Roman, I'm really impressed with the build quality. The covering looks particularly well done.

Sorry, I didn't realise that some new posts are in this thread.... Embarrassed


FFScott, I did a tutorial about the pilot on SFA. http://www.smallflyingartsforum.com/YaBB.pl?num=1240853899/0

It's a Bostonian, so the span is 16 inch.

Woodster, thanks for the kind words, but the covering looks in the picture than it is. In the meantime the motor exploded, so it's not "clean" anymore...

For those who havent seen it, I posted some picture and vids on the went flying thread. Starting from #958 http://www.hippocketaeronautics.com/hpa_forum/index.php/topic,2281.930.html

Im am really pleased with the flying. It flies better than I expected Cheesy

Tom, I am very happy that you build my Bostang. Hope that you have a lot of fun with it.
I will follow your build with great interest. Looking forward to the red tail Bostang Grin

Roman...

Started the Bostang B-51 and have the sides done.  When I placed the sides over the top view I noticed that the sides were short in relation to the top view.  I just lined up the front and sides and pinned the final break in the tail taper and pulled the tail together...will post pics later...cameras battery is charging....

Made some good progress on Roman's Bostang B-51  I love this little bird.  I don't know how you guys build with this contest balsa...got some sticks from Alan Cohen and they are great...but my big fingers are used to the hard stuff I get at the local craft store...can't tell you how many times I broke the fuselage longerons and cross members...here's a couple of pics of the mockup of the bones so far...lots to do yet but really like the looks of this little plane... A BIG THANKS TO ROMAN FOR A GREAT LITTLE PLANE Grin Grin Wink Cool

Tom,  great to see your Bostang coming along. Thanks for the tip about the flaw in the plan. I will check and correct it. You are fast, I am sure we will see the red tail Bostang in colour soon Grin

WoW...this fuselage and the light sticks I used are a real challenge to these clumsy mits of mine...I should have looked at Roman's pics before starting my build...I cracked the center section and built in the dihedral from the center of the wing...ooooops Embarrassed Tongue

Today I spent the time correcting my construction mistakes...corrected the spread at the bottom of fuselage just ahead of the wing...built a new center section of the wing and added the old outter panels at the proper dihedral...fits the fuselage much better, as designed  Wink

Added the "A" pillars and the contours of the rear of the canopy.  Here's the latest pics of the mockup of the bones...
