Lets start where I left off 4 yeas ago: The Airwolf is dead.
The amount of time and effort meant I could never enjoy flying it. It was a shelf queen, but in all actuality I really haven't been doing much flying, more like no flying, the last few years.
Sure dropped into the forums every once in a while to see what was going on and I religiously browsed KobbyKing but besides some microquads I just didn't fly.

Recently I worked with two different guys on two different jobs that used to fly too and that got me back into wanting to fly, something, and that's where "the Lady" died.
During some sport flying something "popped", that's the best I cant describe it, I heard it and I felt it. It was during fast forward flight in a high banked turn, it just rolled over and went in hard. Its fixable but I just didn't enjoy flying it so I won't. Instead I decided to build a plane and that's where this rant starts:

During the past 4 years when I've looked at the site, besides multirotors exploding on the scene, it's all been the same. Literally ,the same. The same planes being build, the same style, the same construction. That last bit is quite important. The same construction. Another forum I frequented for all intents is as dead as my Airwolf so I looked for another forum, to find a plane to build and found one called the FT Viggen. That, is what this hobby should be. That one single plane. It may not fly any different but it's beautiful and elegant in design and...Continue Reading

My computer is dead, the hard drive is dead or about to die, I'm hoping to clone it in another PC before it's totally dead. If not I've l;ost a lot of photos of this build. But...

Airwolf hovered a few times but the heli had to come back out. Actually it came out a few times.
I had a problem with the landing gear "binding" when the fram was bolted into the fuselage.
Turns out the I still had the settings in the TX set to gyro so the retract servo just wasn't moving properly. One set correct the retracts are great!
I had been using a test RX and model in the DX7 and THOSE settings were correct, that's what made the diagnosing a brain dead moment.

All the in and out trying to fix that problem broke the the wire going the gyro sense so my last few flying attempts were with the gyro gain at 0(!).

Video is always hard but photos will be coming soon as computer problems are fixed.

Got the front wheel to pull up way into the cabin.
Notched the frame and adjusted the arm. had to grind a little into the rod for the jam nut to catch.

Have to take the heli out of the fuselage to find out why the retract is so slow and strained, they extend as they should.

As I said last night the mechanicals were done.
That's were everything pretty much went south.

It seems actually mounting the helicopter in the fuselage messed up a few things:
1) The retracts no longer work properly. It strains to lift the wheels.
2) The front wheel does not retract completely BTW and there's little to fix it, although I have a radical idea.
3) This one hurts! I thought I had measured the cabin. I even test fitted but someplace down the line the cockpit does not fit and there's no way to get one in there that will look decent. The floor will have to be over the windows. Combine that with:
4) The cabin no longer fits easily. as mentioned yesterday the landing gear has to be up to fit it then it has to contort to get the screws in place.

But I did spool it up and said what the heck. I really didn't care what happened at this point, lifted and hovered around the backyard at twilight.
I will say the navigation lights work and it looks pretty good. Not worth all the work though.
It has to be taken back apart to figure out the retracts.
Going to replace the battery tray I cut, and tint the windows to complete it.

So a mixed night. Quite a few things didn't work but all in all it flies although it feels heavy at times.
I need to tweak the pitch curve for less negative pitch for a floaty landing.

As the title says, it's mechanically ready. I got some over spray on the windows and I'm generally not happy with them. I may replace them with some soda bottle plastic. Tint wasn't that hard at all.

Expect photos and videos tomorrow.

Clear coats are on and I'm glad I went shiny. Paint is not perfect but it's good enough.
LED navigation lights are in. Red, green, strobe and "rotators"!
Faux turbine LEDs are wired up and work! Off at low and come on with the collective. And didn't explode at full this time!

I'm pretty happy with it tonight, It's looking good! (!) but there's always tomorrow ):

All my parts are in! YES! Blades are really ugly but if they balance they'll look OK spinning. Need yellow paint. Fuselage is drying, work had AC so little humidity.
I wet sanded through the grey on the cabin so I sprayed on a light coat just to cover. After drying I grabbed the paint can with the clear top, I had already laid one layer of clear on the fuselage, and started spraying. It was the GREY!
So the cabin will get another coat of white.
Second coat on the fuselage went on nice and shiny. The 2nd coat on the tail box cover somehow got dirt in it, so more wet sanding to clean it out ):

I've decided to mount the tray to balsa and screw the fuselage to that.
Still need to figure on how to keep the nose wheel from sagging.

Tomorrow I'll get the navigation lights mounted, by some red LEDs for the fake turbines and cover the open intakes.

No photos.

Rain the next few days so the humidity will be way too high to lay anymore paint on.
The color looks really good and hopefully will look better with the clear on.

Not much to say but YAY! Hopefully the paint doesn't come off with the tape.
I may leave it in the sun or use a hairdryer before pulling it off.

After this coat, actually 3 light coats,dries I'm going to separate the parts retape and ad a few more before wet sanding everything and clear coating.

The photos with flash makes it appear lighter than it is. It's definitely like the full size replica, which I've only seen photos of so...

Guess I had more to say than I thought.

Sunday WAS the day! The day I pulled the blue painters tape off to change the placement and pulled off the white paint/primer down to the fiberglass in one spot!

It's being repaired but this time I waited 48hours before wet sanding.
Tomorrow I'll through some white on and try it all again Sunday.
I'm going to wait another 48 before wet sanding that then 24 for it to dry.

The white is on the Airwolf. I have clean release blue painters tape plus some regular masking tape and it going to get it's coat of black.

I'm actually pretty nervous about this as I think, besides flying it, this poses the most risk ):

Need pointers.

Hard to see in the photo plus my cheap blue "painter's tape" pulled the white up to I had to paint crooked.

Automotive clear coat is on the left half, Krylon Matt is on the right.

Neither clear reacted with the bumper or white paint.
The Matt is very flat, once on it doesn't appear to even be there, I'm going with the clear, Once it stops raining and the humidity drops.

Just another rant. This fuselage is screwed from the mold.
Was about the glue the horizontal fins on and the lower "pods" are crooked.
Too late to give up now.

I got lazy and didn't do another primer coat. I'll live with it.
White is on, This is the 3rd layer before wet sanding again.

From wet sanding so no photos of the Airwolf tonight.

A couple more coats of primer with wet sanding since I posted photos and the cracks are almost gone!
One more coat of primer and I think it'll be ready for paint.

Bluebird servo is attached to the flimsy plastic tray. Retracts took more work.
Really a pain to set up. the rear needs much less "mechanical gain" than the front. With the single control rod the frame tends to bend into a U, probably not an issue when it's bolted to the heli's frame but I replaced the single rod with two and am working on a plywood tray.
All of it will have to be tweaked once it's installed on the fuselage.

I was worried about the servo tester as I replaced the 5k pot with a 10k but it works with no apparent loss in resolution. Used it during the retract set up.

Getting closer

Finished the Esky servo tester to drive the gyro sense.
It was down to 4.6g before I soldered the wire directly to it and before the heat shrink.

Kinda a waste since it's heavier than just stripping the case and knob but oh well. That's the way this project is going.
But at least it looks good.

It got it's first coat of primer and every crack I fixed plus some I didn't even know of showed up plain as day.
Back to sanding and fixing )':

My servo is in the Post Office and THIS branch's lobby is closed for the holiday.
Deliverys are still scheduled but my package is stuck in the branch until Tuesday. meaning nothing until next weekend more than likely.

My retract servo is waiting at the post office.
The cockpit is done, the fuselage is all wet sanded and ready for a primer coat, need some solder to fix the landing gear *sigh, started work on mods to make the landing gear wires pretty, need a 5kohm pot from RS and some tint scraps still.

Wife is making a Stringfellow, sooner or later, for the cockpit.

Hope the LHS has some white tail blades, they seems to always have the color I DON'T want at the time. Want black they only have white, want white they only have black.
Have some matt clear Krylon, hope it's enamel compatible, need to get the actual white/dark metallic charcoal.

Have a wedding tomorrow ): but this is going to be in the air, at least in primer coating, by Monday.

I hope.

My Esky servo tester arrived today so I got some motivation.
The servo tester started off at 8.6g with case and metal knob. Just removing the case and knob:

Description: This has potential.

The potentiometer is large and there's a switch for for some reason, that didn't have access through the case.
Changing, or replacing the pot with resistors, and replacing the switch with a jumper will get it a few grams lighter, the LED won't be needed either.

Now on to the "good" stuff:
