Found some time late yesterday and this morning. Yea for me!!!

An Ode to Bodywork.

Bodywork, Bodywork my oh my.
I really hate you, not sure why.

A necessary step you are, but it's like going through hell.
Done correctly, Airwolf will be sweet, only time will tell.

Bodywork, Bodywork oh how I dislike thee.
I enjoy scale modeling, but you bring me no glee.

A painfully slow process with no end in sight.
But I will win. I have the vision, the patience AND the might!

I'll continue on as there is still lots and lots to do.
But I am done for today, Bodywork. And to you I say.......Adieu.

Got the styrene parts glued back on using medium CA. Nice and permanent now.Started my favorite activity......bondo and bodywork......

Sculpted what I think is the radar altimeter out of balsa......

Wife bought a new Cuisinart food processor so I figured I'd try it out. Threw a bunch of various shapes of stryene into it, pushed the button that said "PULVERIZE" and what you know, got some nifty crafted parts out of it!!



And a overview of the bottom. Still some detailing to do, but getting there......

Trying not use any 3D printed parts if possible, so have been fabricating all of the details myself. Hopefully I am not embarrassing myself. Got my replacement doghouse so I think I will flip the fuse over and start working on that next. Tested the new configuration on the "bad" pieces and am pleased with the test. Will turn out nice and be relatively easy to fabricate.

Till then, keep those rotors pointing towards the sky!

coming along nicely Steve. I like the idea of using your hands to craft things instead of a machine unless absolutely necessary. I think its what craftsmanship is about.
I am curious as to what the holes being plugged by the tags are.

Thanks Doc. Although time consuming, I am enjoying the fabrication part of this detailing process.

They are my vent/overflow lines for the turbine fuel tank. The full size has them more forward, but I was unable to locate them in the "correct" location due to the turbine fuel tank being in the way. This was the best I could muster.

ok I thought maybe it had to do with the turbine mechs.

Well, making decisions on the new house coupled with getting the old house ready to sell is all time consuming, but managed to squeeze in a few hours of me time.

Got to a happy place with the belly details so have moved back on top and started the doghouse mods. My first attempt, although a "failure", had the fortuitous result of allowing me to "do it better". Repositioned the exhaust outlets for better symmetry right-to-left, and have a most awesome solution to make the rear doghouse removable that has significantly reduced the length of the visible cut lines. Cant wait to show you all the new and improved version 2.0. But you will have to wait until I am finished with it! Will show the mods step by step over the next few weeks.

Started off with a new doghouse and immediately reinforced the interior with carbon cloth. Lots of vent holes and big exhaust outlet holes need to be cut in the doghouse and the carbon cloth will help with stability....

And because I am super nice and super friendly, I'll go ahead and share a pic of some hysol drying (gluing on the side vents - I know Airwolf did not have them, but I really like the look, gives it a "fighter jet" look, so I made a executive artistic decision to install them. They will look nice, I promise!)....

Then moved to the front cowling and laid out the vents....

Used the step drill to get nice a nice radius at the corners....

Forgot to take a pic of the rough cuts, so here is a pic of the completed openings after hand filing.....

Turned out pretty good.

We will continue on with the doghouse mods and post up pics as I get each step completed. Till then, keep it real homies!

This scale modeling stuff is hard!!

Worked on getting the doghouse vents cut in. Started with layout to verify locations looked OK.....

Then started cutting and shaping...

Various views of the completed holes. Getting them looking right took forever (at least it was a difficult task for me). I am happy with how they turned out.....







Also got the exhaust cutouts started. These are not the final holes. These holes are just the start to get things positioned. Final holes will be larger to allow a 5mm gap between the exhaust outer pipe and the fuse. (This pic shows the exhaust inner pipe). you can also see the new panel line for the removable doghouse......

And pics showing the new and improved removable doghouse sections. The smaller lower piece is going to be permanently glued onto the main fuse and the gaps filled in to make them go away. The larger piece is removable held in place by 3ea 3mm counter-sunk screws....

The new removable doghouse works perfectly. Easy to manipulate, minimal gaps. Super pleased with how it turned out. Gotta thank you all for pointing me in the right direction. A little more shaping and fine tuning and the doghouse will be complete (minus some raised panel and rivet detail which will be done after primer).

Next up is another "major modification". The retract winglets. Vario suggest these be held in place with pan head screws. I dont like the look of pan head screws, so I am going to permanently attach the winglets, but will make the ends holding the chain guns removable (they will be held on by magnets). This will give me a nice invisible joint between the winglet and fuse, and still give me access to the retract mechanics and servos. The removable chain guns will be a nice feature set to help prevent hanger and transportation damage.

Getting closer and closer to primer time, but still lots to do.

Steve, if this stuf was easy, everybody would be doing it. not everyone gets deep into it like you do. engineering and being creative is what makes a real scale modeler. you are doing a great job and when its done and sitting in a nose in hover right there in front of you is when you will take that sigh and say, it was all worth it.

Well done. If I could make a suggestion as to the permanency of the winglets, when I was at the stage of gluing the horizontal surfaces for my CH-139, I used Shoe-Goo rather than epoxy or CA. There was more than enough gripping area on the stubs for the glue to adhere to and since in yours, there is a structure that will help to hold it from drooping, a couple of well placed glue lines will hold it in place. This will allow their removal in the event of repairs being needed for anything internal that might only be accessible with the winglets off (landing gear, machinegun system). Ultimately, it's up to you. Those vents and fitting of the upper to the main doghouse look very, very nice. I can tell you from building an Airwolf doghouse for a 600 size, that the screen angles will give you some fun. Take care.

Allrighty then!!

Kickin' ass and takin' names! LOL!

Got some stuff done on Wolfie this weekend and very little to show for it. LOL!

Added bondo fillets to the thingy's on the bottom of the fuse. Doing this was a complete PITA! Used my finger to fillet in the bondo, then sanded smooth (as smooth as I could - it was tough)......


Then started on the BIG mod. Redoing the winglet/chaingun pods. Vario suggest mounting the winglets with panhead screws that would be quite visible and noticeable. I didnt want a bunch of visible panhead screws, so I created a bunch of work for myself :-). I am permanently mounting the winglet and making the chaingun pod removable. I am not finished with it yet, so bear with me. I will show what I have so far.

Started with a very nice winglet.......

Cut out a big hole for the chain gun pod.....

After sanding and fine tuning, ended up with a nice looking hole in the winglet....

Started rough cutting some fiberglass parts to make the chain gun pod and removable bits. 1.5mm and 1mm fiberglass sheet being used here....

Took the piece I cut out of the winglet and started making the outer chain gun pod. This part is what the chain guns are mounted to......

Filled in everything and sanded smooth for a nice looking piece.....


Then started on the removable plates that will fit up to the winglet on the fuse....

Showing the fuse without the winglet....

Winglet in place (this part will be eventually permanently fixed to the fuse)...

And showing the removable portion. This whole assembly will be held in place by guide rods and magnets.....

In this pic, the aluminum tubes reinforced with the wood collar are what will slide onto the locating guide rods. The guide rods are glued to the fuse, so when the removable pods are put in place, they slide on some guide rods for perfect repeatable locating and help with rigidity.

By having this outer portion removable, I have eliminated the the need for visible pan head screws and still have access to the retract servos and retract assemblies. Added benefit is the guns will be saved from hanger rash and possible transport damage. I'll shoot a short video after it is all finished (waiting for the guide rods hysol to dry right now). Hopefully this works!!! LOL!

Since I was bored and didnt have much to do, I decided to carve out the rear tail light housing. Some sanding sealer and this part will be fixed to the tail fin...



And filled in the seams for the portion of the doghouse I made permanent....

That's it for this update. Hopefully my removable pod idea works. Will know tomorrow after the hysol dries. I think up next will be cutting out the door and window openings and getting the doors fitted and hinged.

Later ya'll...

You'd think that, but I keep finding stuff that needs taken care of before primer!

Just A Suggestion!!!
Those gun pods would look great if you were able to make them retract!!! (think air retract cylinders!!!)maybe even use an electric retract unit??

Just Say'n!!

I wish. The landing gear retract servo takes up all the space where the pod would be in the retracted position. Just didnt have the confidence in my abilities, nor did I have the knowledge at the time to re-engineer the landing gear retract system to relocate the retract servo when I started this project a year ago. Oh well. I'll have my cake and eat it too on the next build!
