1:3 Bohatyrew 'Motyl' of 1925

Czesc!
Len... here's some pineapple stuff for ya! The wing tube was made from ~3 layers 4 oz. cloth all in one wrap. The 48" long CF tube joiner rod was coated with Kentucky Jelly... I mean... vaseline then enough waxed paper was rolled onto it to give ~ 2 layers. 1 oz. of finishing resin was applied to the glass cloth which was on waxed paper. The rod was placed on the edge of the glass and resin then rolled. This pushed excess resin along to wet the cloth that wasn't. Messy business... yuck! Waxed paper was then rolled onto this and it was taped tight with masking tape and allowed to cure overnight. It was a simple matter to heat the assembly with hot air gun which loosened the waxed paper so the rod could be pulled out. Then the waxed paper was worked out using a scrap balsa stick. The ~42" wing tube to rod fit is pretty good and I'd guess less than 5 thou. slop. Now the board has been cleared to draw the wing! I love this stuff!







Kolejny dzien!

'The Goober Stamp of Approval'... rock on! Thanks PG! I like 'Raisinettes' and 'Snow Caps' candy, too! lol

[ARUP]

Hi Mike! Thanks for commenting because I really appreciate it!!! Do you live on the west of the Great Divide? I'd like to 'go west' and fly sometime in the near future.

[Pgoldsmith]

I’m diggin this thing, inspirational stuff. Definitely “goober status”...

[yyz]

Your craftsmanship and attention to detail is simply amazing but even more impressive is that you actually fly these works of art! I hope to see one of these masterpieces in person one day soon.

To znowa ja! No pictures but the wing rod has getting a fiberglass glass tube curing around it as I type. Fiberglass and finishing resin... what a messy proposition! Yuck! The basic fuselage box is completed! Whoopee!!! Some gussets are still being added to keep the sticks from getting loose. Some of the sticks are drilled to accept toothpicks with glue. That'll really lock the sticks together! Now, the wing construction can begin. Once the spar location is known exactly then the wing tube can be put in the fuselage with appropriate bracing. Then the landing skids mounts can get fabricated and tied into the wing tube supports. Then the tail feathers... then.... lol. The wing looks to have a Go 190 foil so I'm going to smooth it over toward an HQ 3.5 using the TLAR method... just like I'm doing for everything else on this model!



I want to finish this one pretty quick so I can start on my 'Secret Project' for the Horizon Hobby Aerotow!
Dobranoc!

The nose bows got sanded on the inside to fit some plywood. Sandpaper was wrapped around a cardboard tube for this process. The sheet of ply was slipped inside then marked to get cut. More CF tow was laid down with epoxy and the ply was put back in place and clamped until the epoxy cures. Making sure the CF tow gets saturated with epoxy sure is a messy business.







I noticed the tail post isn't square so that will have to be 'fixed'. Do widzenia!

[ARUP]

Thanks for your support, Len! Yeah... my house has a little bit of a pineapple and acorn theme in it!

[lenb]

At some point you have to run out of ways to amaze us. Another cool project..Thank you mike.


PS.
Love Pineapple too

Witamy! Almost finished getting uprights around the nose! To try and keep everything aligned formers are getting built into the fuselage in the front section.



To wszystko!

[ARUP]

To znowu ja! Uprights and part of the landing gear mount reinforcements in the form of lite ply and CF tow has been added. When the epoxy cures more ply will be added to continue around and to the nose. It's sure is hard to photograph these big birds to make sense of what is going with the build so just look at previous photos to compare.



Dobranoc!

[ARUP]

Dzien dobry! Thanks Steve! It's going to be a big dopey model but should be fun! Tail skid mounting done! The mount block epoxied inside the fuselage is spruce and the marine ply exterior guide block was installed early during the crutch build. A paper pattern was used to check the angle of the skid as it exits the fuselage. The skid is 1/8" piano wire and will get painted and installed after covering.





Do jutra...

Looking good Mike!

Wiecej! Big box building begun! The upper crutch was left inverted on the board and the lower crutch was blocked up over it. Bubble levels and squares were used to make sure everything stayed aligned as much as possible. A couple of verticals were let between the two crutches after the vertical ply tail parts were glued in place. More diagonals have to be fitted into the rear section and a tail post was glued in place. I hope to finish the rear part early tomorrow so the front section can get some attention.







PA pa!

[ARUP]

Witam ponownie! The lower crutch was built on top of the upper for symmetry. Marine ply is used at the end because the tail skid will need lots of support. The diagonals were reversed so they will match once the crutches are joined in their 'normal' positions. Time to block the crutches to the proper height and start adding the uprights. Sorry if this stuff is 'wordy' but for those that don't like it... too bad!



To wszystko!
