Now there's only one ship to work on...
Have done a few things already...
Marcus
-
Hi Marcus. Great job writing in CLW, I enjoyed reading your contest report. I still have to finish the other article. Thanks for the entertainment.
Rusty
-
Thanks Ty and Rusty!! H^^
Marcus
-
Hi Marcus,
I suspect you will end up with an outstanding model when finished! Keep up the good work.
BIG Bear

Thanks Bill.
Marcus
-
I hope this works... S?P
Marcus
-
Hope you smoothed that Super Fil before it set. Makes for a lot less sanding or using of metal rasps. The stuff makes for really strong joints too.
-
I did Doc.
Tomorrow I'll work on the ship and let's see what I can come up with... ;)
Marcus
-
Some more pics...
Marcus
-
Marcus How far does the plane come apart ? looks like the Rudder and not the stabilizer , and how about the wind? ???
-
It's all like the plans, everything comes apart.
It's got a adjustable rudder...
Marcus
-
Still looking great.
-
Thanks Doc.
More Superfil...
Marcus
-
More superfil... S?P
Marcus
-
What you guys think??
Marcus
-
A lot of work to get that tight a fit on a "take a part". I like it.
-
Marcus,
Really nice work! You have patients and pat attention to detail.
So I guess you switched over to Superfil and no longer use Epoxy and balloons. Correct?
Charles
-
Thanks guys.
Charles, I still use epoxi and microballoons, only now I use the superfil over it to get a smoother surface and it sands much easier...
Marcus
-
Looks nice Marcus, I've been watching from the start. Models are kind of like people, as they develop, they have to go through that awful patchy scabby blemished looking stage before they turn pretty. LL~
My Yak-9 is in that cruddy teenage horror looking phase today, soon to turn into a thing of beauty almost overnight, I hope. I used microballoons for the first time and made it through the learning curve fairly well. But have had to use spackling to fine tune and blend the curves. I hope it won't crack later. After the 1000 grit treatment, I soaked the spackle with CA to harden it. I think I'll look into this Superfil next time. I learn a lot watching you guys build planes. Thanks for posting.
And I finished reading your CLW articles, great entertainment, I appreciate that too. I even got my picture in that issue. ;D
Rusty
-
Thanks Rusty.
Actually, i had a few soft spots, caused by bad lamination..
Thought it was better not to risk any possibilities of future problems, so i skinned the soft spots and did a few patches, no more problem.
An example of epóxi+ microballoons with superfil on top...
This build has been a learning experience for me... I just wish my life didn't get so crazy and unpredictable, so I could accomplish one schedule once in a while... LL~ LL~
Marcus
-
Hey life is unpredictable at times. That is what keeps us going. I do like your build of this plane and all the others. Haven't figured out the house computer so I can watch videos yet. So they wait til I get to the lap top in the shop. H^^
-
Crazy and unpredictable... that's how you know you've got a life. H^^
Not to mention pain in the moving parts, that's how you can tell you're still alive. LL~
Rusty
-
More fillets...
Marcus
-
A jar of alcohol setting close by will help smooth the filet material before it sets up. Amazed me how well the material stays in place. Used it to finish the gap in the profile Ringmaster and also amazed how much strength it added.
-
More pics... That is a lot of work... LL~ LL~
But I love it!!
Marcus
-
Just a few spots to fix, almost ready for the veil.
It's really cool to have my cave...
Marcus
-
Marcus, The "Mark" of excellence.
Bit by bit you're getting there. Looks good, fillers look clean sanded.
Really nice scoop!
CF gear! Did you say where you got it?
Keep up the good work.
Charles
-
Hi Marcus, It's going to be REALLY nice! Great work so far.
BTW: I have forgotten what engine you are using. ???
Thanks!

The CF gear was made by my friend Osni.

Thanks for the cool words guys...
Marcus
-
A little more detail sanding and I'll take it apart to apply the veil...
Marcus
-
That is still looking great. I just can't imagine the color scheme. H^^
-

Yeah John, that's a bit of a problem, me neither... LL~ LL~
Marcus
-
Thank you Ty
The veil is getting on... This thing is wonderful!!
Marcus
-
Marcus,
The "Mark."
Starting to come together. Your efforts are really paying off.
Looks really good in this photo.
The model is shaping up.
-
Thank you Charles!!
Marcus
-
Hello Marcus
A job well done,the Thundergazer is looking great.
Juan
-
Thanks Juan
A little more done.
Need a few more coats of dope and sanding we go... ;)
Marcus
-
Marcus,
I see the CV overlaping on the fuselage.
My guess is, those areas are twice as thick.
Is this going to create an issue in finishing?
Model looks really good! H^^
-
Marcus, you are going to be done finishing and flying before I am with RI. I too over lapped the CV when I tried it the first time. When I was done with the finish you could not see or feel where the over laps were compared to using fiber glass. Even Poly-span leaves a little ridge if not sanded right. Can't wait to see the finished product.
-
Me neither Doc... VD~
Like Doc said Charles, when you sand it, the overlapping vanishes... This is pretty good stuff...
Need to come up with a painting scheme... Just a blank yet...
But there's a lot of sanding to be done, and primer after that, and more sanding after that... I think I have time...
Well, back to the shop, after all,it's not gonna sand itself...
Marcus
-
Hey Marcus, the late Rusty Brown told me that when sanding carbon fiber do not blow the dust off or even rub it off. Just put a couple more coats of clear on. He stated that it will fill the grain better. I know it took less dope to get it to the primer stage.
-
Thanks for the tip Doc.
I've got a paint scheme!! o2oP... Now I have my heading...
Marcus
-
I've done a lot of sanding and it is basically ready for primer.
I see all the work I've done and then check a few pics from some NATs ships and think to myself: "20 points is not enough...." LL~ LL~
I'll post a few pics when I have it primed... So far, so good... Veil is the best thing on Earth!!

Marcus
Marcus,
Do you really think CV is the best thing on earth? You have used silk correct?
Does it lay better? Fill with less coats?
Tell me why?
Charles
-
Charles
I don't think I have enough experience with it to compare one with he other.
I never really cared about my paintjobs, only recently.
What it seems to me is it is easy to lay down, fills with 2/3 coats of 50/50 dope and sands beautifully...
It's expensive though...
I intend to stick with it for my stunters...
You should give it a try....
Marcus
-
Primer is on... Sanding on the way.
Marcus
-
Yes the tedious part of finishing. I was told you sand/rub with 400 grit until you can almost see thru the primer using a good sanding block. Use a good light to see the surface as you go. You are going to be flying before I get my RI ready.
*RI=Ringmaster Imperial.
-
Primer.
Second nicest thing I ever felt.
Way to go!, The Mark!
-
Lots of sanding... S?P
Not finished yet. Base coat soon.... 8)
Marcus
-
Now you know why some of my planes don't look so good. You have way more patience than I do.
-
Is it soup yet?
-
Almost ready for base coat.
What you see, 41.2 Oz...
I hope I can keep it light enough... ;)
Marcus
-
Marcus,
Hey! Hey! The Mark!
Not nit-pickin, but it doesn't look like you've done much to it since your last post, except for assembly?
Are you working on a secrete project that's taking up your time? LL~
To prove I look all your photos over, always do, is this a repair?
Another thing I just thought of. To paint that model it has to be disassembled. One would think?
You will have to tie the scheme in with all the parts, then separate for paint. All paint areas will have to line up from one part to the next. That's a task in itself, unless you keep it simple.
Got any ideas for that?
Looks great! Doesn't sanded primer feel nice. ;D
Charles
-
That's because sanding doesn't show that much, but believe me, i've done a lot of it...LOL
Marcus

Yes Mark, I was kidding about your efforts. You've worked hard on this model. H^^
Hey! You're still not getting off that easily. LL~
What about that crack, if it is? Gotta be a story there.
What happened?
Charles
-
Getting back in business...
I've done tons of sanding, and am totally happy with the result.
I had to finish ghe tank compartment, and so I did.
Winter sucks....
Marcus

Looks to me like it's a "Come-Apart" model, as we call them locally. Wing comes off, stabalizer comes off, elevators come off the stabalizer, flaps come off the wing, LG comes off, rudder comes off, fin comes off the fuselage, etc. Just like the kit shows. Locally, most make their wings in 2 pcs., so they'll fit into an airline legal sized box for flying to NATS, Europe, etc. When they are around home or after arriving at the contest, usually only the outboard wing is removed to fit into the rental car. Looks like Marcus has a one piece wing, however, like Thundergazer designer Dave Fitzgerald's. So, now you know what that crack is. Often camoflaged by inklines or paint trim edges... H^^ Steve
-
Marcus you are doing great on the build. Now you want some of the 100+F degrees we are having here in Kansas.
-
Thanks Doc...
Speaking of take-apart stuff... I hope these are the right size....

Steve,
Thanks for that info.
I went back and viewed Marcus' photos.
This is astonishing! It's also quite common I found out.
I could never find the patients for this type of construction.
Every piece must be painted separately!
Great work Marcus! H^^
-
Poor man's painting jig... Old chair, no Money,and some time to kill.... LL~
Marcus
-
If it works, don't complain. Some times I wish I had wheels on my paint stand.
-
John
It did work!!!!
Base is on....
;D ;D ;D ;D ;D ;D ;D ;D ;D ;D
Marcus
-
Well, you will certainly be able to see it.
-
The "Mark" of excellence!
Great choice that yellow.
Much can be done with a base coat of yellow. A good start!
I like it!
-
After some sanding, I thought a second coat would be a good idea...
Now let me paint the canopy...
Marcus
-
Marcus...just wondering...did you spray a coat of white between primer and yellow? ??? Steve
-
Hi Steve
No, I didn't... I'm trying to keep this as light as I can...
I've painted the canopy, by the way....
Will work on the trim....
Marcus
-
I am using vinyl to add some trim...
Hope it gets good....
We shall see...
Marcus
-
That yellow really stand out.
-
An attractive model, with a smooth finish in the colors of your country; it can only be nicknamed "The Brazilian"!!! ;)
-
Thanks guys...
This is done...
Marcus
-
Today's efforts...
Marcus
-
Marcus,
Looks really good! H^^
"ORDEM E PROGRESSO"

Thank you Charles!!
Marcus

Clear is on....
Marcus
-
Buffing... this may take a while.... ;D
Marcus
-
The "Mark" of excellence!
Back a bit you said you were using vinyl for trim colors? Is that trim vinyl?
Did you clear the model? Clear the vinyl?
I love your yellow so much, I'm going to paint my "Mean Lean Stunt Machine" Yellow also.
Exactly what yellow is that?
-
Charles
The vinyl i used is Oracal, from the same ,manufacturer of Oracover, and it worked very well.
I cleared over the vinyl, yes.
The yellow is "Traffic Yellow".... I will try to get the color code for you when I go to the store....
Marcus

Marcus,
Thanks for that.
What clear did you use?
When modelers order vinyl that they clear, I scratch the vinyl up with 600 before I cut any graphics or lettering.
-
A little more... 8)
Marcus
-
I had a little accident with the stab, which made a few dents on the top of it, so I had to do a repair and repaint some of it...
Already just done... LOL....
Now, the rest of the buffing and glue the hinges, all that is missing....
Marcus
-
Yea, I was just about done with my last plane and dropped the cowl putting a wicked gash in it. So, repair, repaint and move one. Fun stuff.
-
Yeah, my last model was just finished, so beautiful, ready for showing off, when I cut a piece of music wire and the cut piece flew in a beautiful arc across the table and speared the wing like a javelin. I guess that's better than an exacto knife.
Rusty
-
So, this is it.
I have to sand one top wing panel and buff the wing, glue the flaps, and assemble everything.
If nothing unexpected happens, it should maiden next weekend.
What you see in the pics 47oz...
So, it will not be the lightest ship on the block, but I am very happy with it.
Marcus
-
That's Bad Ass.
-
She maidens on sunday... wish me luck!!!!!
Marcus

The "Mark" of excellence!
I love quoting lines from movies. From the movie Taken, "Good luck."
-
I'm looking forward to your flight report Marcus. I've been watching this one from the beginning.
Good luck.
Rusty
-
So, here it is...
I hadn't had the chance to check its weight ready to fly... Not good as it came out at 71oz...
Anyway, though it was ridiculously windy, I went on for a first flight and was Lucky, actually very Lucky because the ship showed some bad behavior.
Tail heavy, I felt that right at the take off. I seems like I have to add a little tip weight and move the leadouts back.
I didn't feel that weight was a problem, which was good... I know the lighter the better, but the engine ran ok, though a little rich and there was no overheating.
I was worried about tthat since I din't make openings on the cowl...
Anyway, I'll try to trim this ship a little more, and have a B plan, since it's a take apart, I may try to replace the foam stab/elev for a balsa one and can build another tail part. I've borrowed a scale and will check everything out.
Bene said I should have focused on building lighter and less on a shiny finishing...
And we had a good laugh about that....
This is the first (crash) landing....
Whatever you guys think could help me trim this baby, speak your mind.
Oh, my friend Fabio flew his ship, which is already trimmed and stuff, and said he felt the same thing happening to his ship... So, bad day to maiden it...
No damages other than a scratch on the cowl...
I'll be back with the weight of the parts....
Anyway, I'm very happy, I didn't crash...LOL

Always a good idea on 1st flight to make sure that cg is close to the fwd end of the design's range.
-
Yea, I had a maiden flight on a new design that I wasn't even close with the CG. Very tail heavy. It's an exciting first flight. Yeow!
-
Along with the weather part of it could have been post crash jitters and not wanting to do it again. At least it is flying and you have something to work with.
-
Good going Marcus, thanks for posting. Could definitely see some hunting, and the flag was really snapping in the wind. I held my breath after the engine cut... I bet you did too. Is that the flying site that is right by the beach? I bet wind is the norm there.
Rusty
-
It's getting better....
Ths vídeo was the second day of flights.
It's got better since then...
Need a bigger venturi...

Marcus
-
Looks much better.
-
Well, here's a vídeo of "The Locomotive" at the contest past weekend.
Thanks PAMPA, StuntNews and Mr. Paul Walker for the trimming chart, which was absolutely important for getting this ship to flying a decente pattern.
The 2-part clear I used seems to be failing in a few spots, so i will have to repaint the pipe and engine cowls and touch up some parts of the nose, so I will take advantage of this and make a few move vents on them to improve engine cooling...
This ship is the accomplishment of a boy's dream of one day building, finishing and flying a big stunt ship...
I'd like to thank a few people here...
Mr. Martiniano Quartim, Mr. Randy Cuberly, Mr. Bob Hunt and Mr. David Fitzgerald; all my club members and friends for their support and enthusiasm; and last, but not least, all of you who came here and had the patience of following such a long thread!!!
You all were at the field with me, in my heart....
Thanks and never give up your dreams, never....

The plane looks great. Why are you looking so grumpy? LL~ LL~
