Chic,
Nice, like the idea of the clamps to hold the cloth. Something else I have just learned, and you have answered my question about cutting out for the hatches before or after glassing thanks.

Have a bit mote sanding to do to get ready for glassing the wing on the Trojan but there is a bit of light at the end of the tunnel.
On the bright side Santa left me a Saito 1.80 under the tree so now I have to find the inclination to get this puppy done.

Larry, I learned and have always used that procedure when glassing balsa from my pylon racing days. Thanks to Harbor Freight for the clamps. I see that Santa was good to ya, now press on to get that Saito mounted on the T-28. Smile. Will sand the bottom of the wings today, take Shirley to the movies, to see some girly movie. Don't want to commit social suicide with her - at least not until 2017. Ha, ha. Will glass the top of the wings this evening after the movie. Happy New Year to all the Avenger Guys/Wives/Girlfriends.

Hello Guys - Glassing top of outer wing panels today. Asking for advice on seating, squaring, and gluing the wing center section to the fuse? Thanks Guys. Chic

Install outer panels on center section, absolutely, before you do this!

That way you can make much more accurate measurements from wing tips to tail and ensure alignment.

As I recall, I used Hysol/Aeropoxy to glue the center section to the fuse, all of this done while airframe was inverted on the table.

I would have to dig through my old posts to confirm.

Chic, I just noticed that my fuse was only partially strip-planked and still on the building crutch, which made it simple to verify 2 degrees of incidence on the center section.

You'll have some ciphering and jigging to do for your model, as I notice that yours is full planked and no longer on the crutch.

Hey guys, I've seen that's some guys have flown this avenger on a 3w-75. Do you think the new saito FG-90r3 gas radial would fly it?

Noah, many thanks for the tips, will certainly go to view that posting. I do recall seeing yours sitting there with a level and an incidence meter mounted. I was looking at the fuse where the wing sits and noticed that there is not a lot of wood to glue the midsection too other than the runners - I think they are called F-20 or F-21. Did you beef that area up a bit - Does the additional planking to the fuse help keep the wing in place?? Last question (for now - smile) now that the majority of the planking is done on my fuse, what do suggest as to how to level the fuse front to back when I have it inverted in a cradle so that I can get the 2 degree negative incidence ) since it is inverted?

But the more I think about it, it doesn't really matter whether the fuse is level or not as long as I have the 2 degree negative incidence in when secured to the fuse. Am I right????? Thanks my friend. Chic

Yeah fuse orientation doesn't matter... what matters is that you have 2 degrees relative to the datum/centerline of the fuse.

F20 and F21 "runners" should interlock with formers fore and aft (I think?). Now I cannot remember. But, theses should be sufficient to lock the wing into place permanently, especially if they do interlock fore and aft.

Carl, I'm not familiar with that engine, so I cannot comment. What I can say is that if this model is over-built (like mine) it will weigh close to 50 lbs.... so that might be something to keep in mind.

Just checked... The F20 runners do interlock. They are more that strong enough to lock the wing permanently.

Pretty sure we attached the center section right side up with outer panels attached so we could get the measurements correct from the wing tip to F1? and the horizontal stab. I don't remember if we put in the incidence but it flew great.

Just cut out servo hatches and gear door in wing and found that I made a miscalculation and the door is short...EIEEEEEE!!!!!!!!

Carl, ours came in just over 43lbs and we are using a DA85 and it flew very scale, your not going to win any pylon races with it

Noah, glad to see you on the sight, hope all is well.

​I'm glad both of you are back on site - kicking me in the butt. Glad you guys are there for me. Chic

Chic,
So after waking up at 2am I remembered that we did do the incidence, I only remembered because we bought 2 incidence meters from Robart and had to buy the longer bars

Noah, are you in the process of building anything new or waiting until you get back to Iowa? When are you reporting to Iowa? Smile. Chic

butlern

My Feedback: (15)

I report on March 1.

No building or projects for a while, until we're fully settled.

I do a longer-term project in mind, though. Picture a 55 gal drum with little wing sticking out.

Noah,
Glad to hear you have a new gig. Miss seeing your builds and tutelage especially since I'm driving Boyd nuts with all my questions on my Trojan build.
Good luck in your new position

Noah, are you trying to tell us that you are going "FULL Scale" - Smile. Chic

My Feedback: (15)

Dumb question - but which did you guys install first - the wing mid section to the fuse or the stab? Need to settle a discussion (It doesn't matter which is installed first as long as they are level and the correct incidence is formed). Personally, I will install the wing mid section first. Thanks guys, what did you do first? Chic

butlern

My Feedback: (15)

I did center section first!

Again, I did this while fuse was still on crutch (inverted) so the vertical stab was not yet installed (and not in the way).

redtail

My Feedback: (15)

Noah, will follow your lead of course. I have my fuse in a holding stand and will seat it correctly and include the negative incidence since it is inverted. Will send photos - before final install. It is lightly snowing here and Shirley wants me to take her to Marshall's for a return. She thinks that since I spent over 12 years in North Dakota that I know how to drive in snow/blizzard conditions. O'well, I guess I am now helpful. Boy, the size of this puppy is becoming apparent as I add more pieces. Smile. Thanks Noah. Chic

Chic,
Very nice, coming along. I never notices how small your shop was until these pix, wait til yo see how big this puppy is when you attach the outer wing panels.

Just made up the extensions for the gear doors for the Trojan, now have to trim to size and graft them onto the doors.... never gets easier.

Noah, Chic was kind enough to get me the throws from Brett for the Avenger throws but it didn't list the flap deflection, could you let me know how much you used.

I am going to try and get the gyro installed in the Avenger in the next couple of weeks so I can get into the air this summer (has to be before 10AM or the plane will melt on the runway )

Hope everyone is enjoying the snow, going to be a balmy 66 today
