Cub Flyer Fresno

Do you ever ask yourself this question...


WHY THE HELL AM I USING INSTANT GLUE IF IT'S NOT GOING TO SET INSTANTLY???!!! I feel like I need to apply the glue and clamp the parts then let it set overnight! SHEESH!!!

Tom, I think you pointed this out and now I think about it all the time! Thank you. 😉

Okay guys, I started to put the tail feathers on today, but there is something off and I can't quite put my finger on it. I got the vertical stabilizer, aka stabulator, aka fin, in line with the center-line of the fuselage, aka fuse. aka big box thingy where the pilot sits. First of all, I found out that the prints are wrong, the top view shows one thing and the side view shows another with respect to the tail. I then discovered that the horizontal stabilizer was not build perfectly as well, a little sanding bar and table saw took care of that. But still when I put everything on the fuse, it doesn't measure out quite right. I did notice that, even though it measured out perfect before, the wing doesn't seem to be square with the fuse either.

I'm going to have to go back at it again later, sometimes it helps to get away from it for awhile, things will come into focus better. Also, my back and legs are starting to bother me, can't stay hunched over that thing as long as I used to.

Oh, I also got the dowels glued to the side of the fuse using medium CA. Only took about two hours. I went out and did some yard work while I waited for the CA to cure. Yup, it took quite a while for that stinkin' instant glue to set!!!

At least it dries faster than Titebond.

VincentJ

I use Titebond II to build Flyer, and if I give the glue 20 minutes to set, it's strong enough for me to unclamp and continue building. It may not have achieved full strength, but it sounds like it's faster than what David's using! LOL

Something is wrong if your CA is taking a couple hours to set.

Cub Flyer Fresno

VJ, all I have to say is: Yeah, no duh!

And Tom... Yeah, no duh!

It's the Tower Hobbies Build-It CA. It was the cheaper of them all... oh... um... yeah... well... hmmm... Guess I'll have to invest in some accelerator.
Maybe I'll write Tower and see what they say. They usually stand behind there stuff, right? I mean, at least that way they can avoid getting hit when you throw it back at them! (Just kidding, it's what I do!)

Cub Flyer Fresno

Okay, as far as my wing/tail alignment issue goes, Tom noted in a private message (sorry Tom, I'm spilling it!) that he thought the fuse looked a little crooked, a slight banana shape if you will. And this could very well be! I did put it over the plans and it looks straight compared to the plans, which I have noted before are not perfect!

So, with that said, what is the consensus on squaring the wing to the fuse? When measuring from the wing tip to the trailing edge of the fuse, I get 1/4" difference, maybe just a touch less (3/16"). It's 42-1/16" on one side and 42-1/4" inch on the other. As long as I try to keep 0 incidence in the fin and keep the stab straight with the wing, will it hurt?

(Whoa, after a rough day at work, and a Monday at that, my head is starting to spin!)

Thanks in advance guys!

To me, it looks like the fuselage bend to the left (looking from the rear), just aft of the cabin area.

Short of dismantling and rebuilding the fuselage, I'd mount the wings and square the stab to the wings.

I wonder if Callie would have a Chiquita Banana Gal decal he could put on this airplane? From what I am reading it might be appropriate. ;-) Oh well you aren't the only one who has built a banana before and you won't be a the last one either! I know I have had it happen before.

VincentJ

Now that's funny...sorry David!

My Feedback: (6)

Tacky I know but I figure better to laugh it off then cry over it!

Cub Flyer Fresno

Okay guys, have we all had a good laugh? Are we through now? Hmmm?

Oh, I was just going through some of my photos, and here is one of what the kit looked like when I got it..



Well look at that! The fuse was already glued together when I got it! Hmmm... does that mean it was already a banana? But, in the original builders defense, I did put it over the plans and it appeared to be straight. I need to go back and look over the plans again to see. There are some other things that aren't quite right too, but I'm not telling what they are, no one will ever know.

My Feedback: (6)

It wouldn't be the first time the plans were a little wankie, it's not always easy to tell with the naked eye. I sent a set of plans to a laser cutter once and he told me he hadn't seen a set of hand drawn plans yet where he didn't have to split the formers and flip the two pieces on top of each other then pick the best side to use. The two sides were always slightly off even on commercial plans. The exception appears to be with CAD plans where the designer can flip the drawings to check to see if the two sides match.

VincentJ

OK David, are you saying that the banana was already rotten before you got it? ...sorry, I couldn't resist!

Cub Flyer Fresno

I wouldn't say rotten, just overripe. (Oh my gosh! I've got to do the next build on RCG, these emoji's are worthless! )

TomCrump

It's not that bad, David. I'm just saying that it could be the cause of your alignment issues.

I'd just line up the stab to the wing, and make the fin 90 degrees to the stab's trailing edge.

Cub Flyer Fresno

To late Tom, you already made me feel really really bad! NOT Yeah, I was headed down that path anyway. I just wanted to make sure there wasn't something I was overlooking that would cause problems later.

Thanks y'all!

I have had less than perfect fuselages and have overcome any adverse flight characteristics by maintaining the correct alignment between wing and tail surfaces.

TomCrump

If we are honest with ourselves, we've all built a less than perfect fuselage. That's how I figured out how to deal with them. LOL

Cub Flyer Fresno

Okay, so with all your combined knowledge and experience, how does this look? Be honest now, I can take it!... (uh-oh )



I took my time, measured, re-measured. Then I made sure the stab is level with the wings. Then with it all pinned together I carried it into the living room for this photo op. It's all ready to glue down, except for some final touch-up to the stab and hinging, which I figure will be much easier before the stab is glued down.

Sorry to be so late Daved. My skype was a little goofy and just got your message about this build thread. I have a little reading to do to catch up.

Hello there Ken! Hope all is going well for you up north. And welcome aboard, looking forward to some of your insight as well!

flyingagin

I'm still catching up on the thread. I have the same saw. It has assisted well with many builds. I am still using my original blade (it is rather shot now) and belt. A couple or three years ago I ran across a couple of Dremel saw sources.

Your not too late as far as I'm concerned. Cool links! Thanks for sharing Ken!

You are welcome.

I have a couple of more buried in a gazion links on my confuser that should prove interesting. I will keep hunting, I found (a long time ago a commercial built tablesaw-crosscut-sled.
Could build your own course.
