Kevin my main reason for purchasing this ARF was to help make me a better pilot. I just can't bring myself to fly my built models the same way I would fly an ARF. With an ARF I have no emotinal attatchment to it other than financial attatchment...When I get my flying skills up to my building skills, then I may feel differently.

Amen, Vince
I am seeing that very same thing the closer I get to completion.
I was flying my Kadet last week. And the first thought was.
"Man this thing needs a bigger motor."
Secound thought.
"Scratch that, I need a next level plane" (not the SW)
To improve my skills and do some things the Kadet wont do.
So long way to say. Yep

I started a thread on my Super Cub in Kit Building but can't find the address to relate to it.
Anyone know how to do that, do you have to do the address www.rcuniverse.com/forum/kit-building-121/11606064-buil That must be it, come join me too.

That don't work, crap, what am I doing wrong.

Joe that's funny, there was a time when you didn't have to jump through hoops posting and trying to figure out how to get some place before this web site was sold, I still don't know how half of it works here. At home me and my PC can become bitter enemies, I think it hates me.
Vince I'm about where you are when it comes to flying, still learning the tricks of the fun of flying, truth is I did very little of it this year. Next year I plan to hit some of the areas scale fly-ins, I really enjoy them. I want to learn the art of scale flying so I can compete at them.

Ok, finally got to spend some time on the Space Walker.
Began working on the wing fillets.
First I made a mdf template of the wing saddle and the size of the fillet. The size of the fillet was just an eyeball guess. Nothing to really go by.
I then used that template to shape the layers of balsa that then got glued together to make each fillet blank.
Then I cut some 1/64 G10 to fit the perimeter of each blank were it meets the fuse and the wing.
These g10 strips are only about 1/4" wide. There purpose is to make a hard sanding guard rail for shaping and to keep a knife edge and not break.
These strips were glued on with slow set epoxy using the wing and fuse as a caul to get a perfect fit.
This made for a very stiff fillet blank that I could go to town with 2" radius sanding block.
The 3rd pic below shows the 1/64 g10.
I then chamfered each blank on the band saw. Then hand sanded the cove with 80 grit.
When the paper started to touch the g10 the tone changed warning to take care.
I then glued them to the fuse only (wax paper on wing saddle).
I still have the little turn under at the lower leading edge to do, and the fishtail at the trailing edge and fuse.
The fishtail will be a permanent part of the rear fuse. The fillet will have a field joint at the fuse field joint.
After the filet is dry. It will be sanded flush with the front fuse field joint plane then the rear fuse put back on. Then the fish tail will be made.
For the front turn down, that will be eyeballed . Still pondering that. Lots going on at that part of the fuse.

Joe, thanks. Yes these fillets started last week.
Vincent, Thank you.
You are one of my gold standards for a clean build.
I aspire to build as cleanly as you. One day I won't need so much fill
.
So, worked up the leading edge of the fillet today. I did not wrap the edges with the g10. To much to fit, to get one hunk of complex curve then wrap it then glue it in place.
So I fit each layer glued it in place then fit the next layer, glued and so on. Then sanded it to shape on the fuse.
At this point I am not ready to glue the center wing section to the fuse. So a temporary joint was necessary for the leading edge fillet.
This last photo just chaps my hiney. I'm still kicking myself.
It is of no avail to do a fine job on a part and then carelessly fail to properly execute the installation of said part.
I glued the fillets to the fuse late last night. The fillets touch the wing and fuse on there outer edges. So they can rock up or down a little.
I had not noticed that the back edge of one of the fillets was up about 1/8 higher (not seated squarely) than its brother.
Since these fillets are part of the wing saddle I used epoxy to hammer them home. They aint coming off in one piece. So I will live with my mistake.
One saving grace is you can't see both sides at once accept when the fuse is apart. Also the imbalance is on the very trailing edge, so I am hoping it won't effect flight to much.
The leading edge is very symmetrical .
Next up, the little fish tails that will be attached to the rear fuse and make a matting joint with the front fuse.
Probably next weekend. The salt mine has need of my presence . Seriously I am very thankful to be working. To many of our fellow citizens are without work.

Leroy, after sleeping on it (boy doesnt that usualy sheed some light ).
I think i will sand the upper contour down to its proper position and build the lower contour out.
This is what i was trying to avoid (sanding fillet in place ) oh well, another notch on that sob Murphy,s belt.
If i dont fix it, it will definetly show up on the fish tails symetry. This will show big tim from undernieth.
Amish Warlord (love that name ) Welcome

Don't sweat it Kevin, we all make mistakes and we learn from them. I still say those are the nicest fillets I've seen even with the slight error built into them...it gives it character and will not affect flight performance.

Thank you Mike and Joe for the nice compliment.
And thanks again Vince.
I will go ahead and correct the mistake. The reason is the mistake gets magnified on the fish tail.
Because of the angle of attack. 1/8 difference In elevation makes the vanishing point of one tail
3 1/2inches long and the other 4 3/8 inches long.
To cheat that would significantly change the contour of the fillet.
The picture below illustrates.
Also because the rear of that fillet is 1/8 high it is also 1/8 narrow. So those two triangles get really cattywampus
I would be able to see that on a flyover.
I stopped kicking myself as soon as a resolution was arrived at in my mind. It then became a challenge.
Onward......................

Much like Vince and joe said, making mistakes is normal, hiding them takes real craftsmanship which you have. Not everyone admits his mistakes, it's nothing to be ashamed of, your quite normal Kevin. Watch my cub build your liable to see what I mean, ha, ha.
