I have always done the notch in the leading edge of the elevator. Seems there is less bind that way.

Tonight will work on the pushrod...
Gotta check how easy it will be to get this ship together (or difficult??!!

)
Can't wait to get my long shaft 7/64 ball driver by Lee... It'll make that a lot easier...

Just a little more...

Working on that pushrod...
I'ld like to show you my friend Mazzarino's work,the 6 oz fuel tank I'll be using. Not a bad deal for 20 bucks...

Hi Marcus,

Like I said at SSW, you're going to have a couple good models to choose from! Good Luck.

Thanks again Bill.
The elevator throw... Those corners you know...

Marcus

Matt Colan · « **Reply #155 on:** July 21, 2013, 09:06:17 PM »

It's looking real good Marcus!

Just out of curiosity, how are you attaching the rear of the fuselage to the plane?

john e. holliday · « **Reply #156 on:** July 22, 2013, 08:57:00 AM »

In reality, you will probably only use les than half the throw you are showing.

MarcusCordeiro · « **Reply #157 on:** July 22, 2013, 12:57:50 PM »

Thanks guys.
John, I've run a search and it seems that 20º is enough...
Matt, check the pic... I copied one friend's idea...

Marcus

MarcusCordeiro · « **Reply #158 on:** July 22, 2013, 07:11:54 PM »

After being advised of possible torsion on the horn, I've changed the ball link position...
And drilled another hole on the elev horn...

That should work well. I mounted my tail with a screw at a 45 degree angle on the bottom of the fuselage.

MarcusCordeiro · « **Reply #160 on:** July 23, 2013, 06:16:19 AM »

Thanks Ty

I wish all the "planning" I do worked...

Believe me, it gets exciting too...

Marcus

MarcusCordeiro · « **Reply #161 on:** July 23, 2013, 08:16:39 PM »

Me and my big mouth....LOL
So, the new holes didn't work, as the pushrod would hit the stab saddle and not allow the full travel...
Then, plan B... Back to the first holes, but I turned the pushrod around 180º, so the "L" end connects to the flap horn and the ball link to the elev horn.
That should do the trick.
Next time, will get myself some "double" horns...

Marcus

MarcusCordeiro · « **Reply #162 on:** July 25, 2013, 03:00:20 PM »

Almost done with the flaps...

Marcus

MarcusCordeiro · « **Reply #163 on:** August 01, 2013, 03:09:38 PM »

Now, the nose. 1/32 glued, now a layer of CV and then 1/16 over it, as instructed by David F. on the building guidelines.
A doubt, though. What would be the best glue to make this balsa + CV laminate??

Thanks

Marcus

Hi Marcus,

I prefer Z-Poxy Finishing resin or their 30 minute epoxy, either one spread thin and weighted or clamped.

Trim tab...
Will be covering soon... Silkspan over SLC.

Marcus

MarcusCordeiro · « **Reply #167 on:** August 19, 2013, 05:24:23 PM »

The right wing panel has SLC on...
Will be doing the left one as soon as I grab something to eat...

Marcus

MarcusCordeiro · « **Reply #168 on:** August 19, 2013, 08:52:41 PM »

The wing is now all covered with SLC, silkspan to come...

Marcus

Looking good. Now don't forget the scouring pad. Just need to dull the surface.

MarcusCordeiro · « **Reply #170 on:** August 20, 2013, 02:41:23 PM »

Thanks John.
The silkspan is on the bottom, will do the top later.

Marcus,

Could you be so kind as to provide a spread sheet of your builds.

I'm having difficulty following them all.

They "ALL" look good!

You are very kind Charles, thanks!!
Well, there are 3 models right now, the ARF Nobler rebuilding, the TG and the Magnum.
I love building and what I have learned here in this fórum so far has turned it into a much more enjoyable activity.
Hail Stunthanger!!

Marcus

Avaiojet · « **Reply #173 on:** August 21, 2013, 06:06:30 AM »

Marcus,

You don't have to win contest or build super models to set an example of fine modeling. Ability and more importantly, attitude, you have both.

Your kind words, generousity and great since of humor, not to mention your efforts with descriptive builds as you give back, is outstanding.

A great example you set.

Absolutely a fine modeler and gentleman.

Now get something finished!

Charles

MarcusCordeiro · « **Reply #174 on:** August 21, 2013, 05:20:41 PM »

Thank you Charles.

Now, the top... Nearly ready for final finishing...

Marcus

john e. holliday · « **Reply #175 on:** August 22, 2013, 08:25:21 AM »

That is really nice covering job. Now will find it will take less dope to fill. Also you will have to watch how you sand. As Sparky pointed on one of his finishes, two coats of clear and let set for a day. Then sand and two more coats of clear and let set for a day. When you start getting a little sheen to it you can maybe think of the primer coat.

MarcusCordeiro · « **Reply #176 on:** August 22, 2013, 12:56:03 PM »

Thanks Doc.
What I like about this kind of covering is how stiff the wing gets after the silkspan bonds with the SLC...
No rush now...

Marcus

MarcusCordeiro · « **Reply #177 on:** September 01, 2013, 03:25:01 PM »

Molding the nose sheeting... Gonna get it right this time
Couple of days to dry...

MarcusCordeiro · « **Reply #178 on:** September 03, 2013, 12:47:10 PM »

This time I got the molding right!!!!

Avaiojet · « **Reply #179 on:** September 03, 2013, 09:48:59 PM »

Marcus,

Nice detailed photos, as usual.

However.

I'm at a loss here. No, not my mind. Well possibly.

.
That CV is placed over what material? Then you are glueing sheeting over that?

Is the CV doped? Sheeting glued with what adhesive?

Confused a bit, but your model is shaping up.

Charles

MarcusCordeiro · « **Reply #180 on:** September 04, 2013, 05:30:29 AM »

Charles

I'm trying to follow Dave's advice, so first I used 1/32 for a first layer, then I put the CV with a little dope, so it would stay in place, then I molded the top parts using 1/16, and epoxied them in place.

Marcus

MarcusCordeiro · « **Reply #181 on:** September 10, 2013, 02:41:11 PM »

This is my first piped ship.
Gonna work on the pipe tunnel.
Any suggestions??

Working on the pipe tunnel...

Marcus

Matt Colan · « **Reply #183 on:** September 11, 2013, 08:46:57 PM »

Looks good Marcus. My first pipe tunnel I wrapped 1/64 plywood and glued it in with white glue. I would have done it on the next two planes but the design didnt allow me to.

MarcusCordeiro · « **Reply #184 on:** September 11, 2013, 08:53:35 PM »

I still have a lot of work on that area, but it's beginning to take shape.

Did the axis break or the glue failed? What kind of glue did you use?

Luiz

MarcusCordeiro · « **Reply #188 on:** September 13, 2013, 07:05:29 PM »

It broke as you see in the pic, and as Always, I used J&B...
Anyway, went to my friend Martin's shop today and borrowed his scale...

Now I am only giving constructive criticism. Please don't take it wrong! Do your self a favor and you will thank me in the end. Put the spinner on and re-sand the nose to shape. This is the focal point of the plane and has to be shaped right!

MarcusCordeiro · « **Reply #193 on:** September 18, 2013, 03:02:05 AM »

Will do Robert... Got the 1 3/4 three-blade spinner last Friday.
So now I can shape it good!!!
Got some 13X3.75 BE CF props, and Marlus will help me get them ready for action.
Will post more pics later....

Marcus

MarcusCordeiro · « **Reply #194 on:** September 19, 2013, 08:21:11 PM »

Adjusted the matching of the tailpiece and the bottom is basically ready.
Tomorrow I will shape the nose...
A few more clicks and it'll be ready for finishing... Can't wait!

Marcus

MarcusCordeiro · « **Reply #195 on:** September 25, 2013, 07:23:22 PM »

"The Mark" of Excellence,

Marcus,

You must have strapped the wing in so it wouldn't move around?

I see your CF 3-blade. Where did that come from? Size? Gear also, same place?

Model is comming together and looking good. Paint is just around the corner.

Charles

MarcusCordeiro · « **Reply #198 on:** October 01, 2013, 07:15:11 PM »

Actually no i didn't Charles, it's hanging there 'cause the smell, wife and dope, not good friends...

The CF 3-blade is Brian Eather's, 13X3.75. The LG is by my friend Osni.
Just a few more details.... It's been hard, but I'll accomplish this in great style!!!

Marcus

MarcusCordeiro · « **Reply #199 on:** October 02, 2013, 08:15:48 PM »
