I thought a recalled a 2022 date when we last spoke. That definitely makes things get 'real' real fast!

Here to absorb everything about building a KF.
Have fun! One of these days I hope to be able to do a build...

We are having fun. I need to post some updated pictures as we have progressed quite a bit further in the build than what I have posted so far.Have fun! One of these days I hope to be able to do a build...

Seeing as you are not too far away, send me a PM if you want to drop by sometime.

Another joint work session. Shaped provided foam for tips of HS and Elevator, bonded the foam on after that set, then buttered on a coating of micro. After the micro sets, will shape and ad SuperFill to take to final shape. Below is the prices in picture. There were several replications of ... apply Super Fill, sand/shape, Super Fill
I like the results, easy to sand and shape and very little added weight.

We're doing great. We're way behind on posting updates! We have finished all the preliminary work on the right wing and are starting on the
left wing. This, of course, has provided and endless stream of jokes from me since Ralph and I are on opposite political teams We'll leave it
a secret as to which team each of us plays for.
We had a unique method for adjusting the fit of the wingtip and we'll post more info on that later.
During installation of the right wing flaperons we encountered some resistance to movement after getting everything clecoed in place but we finally
realized that it was due to sag in the wing since it was only being supported on the ends. Turning it 90 degrees up solved the issue.
The left wing will have the magnetometer and pitot so it'll be a bit more work but it's going faster overall since we've already done it once.

We'll try to post more often!

As Victor said, we are making progress but not posting much.
I thought I would share the process we used for fabricating the tips of the flaperons. Here are the pictures in sequence.
First, I bought a sheet of 1" thick extruded foam from the local hardware provider, I needed 2" thick so I cut a 2" wide strip and laminated to get a piece 12" long and 2" square. Note, I used a spray adhesive to keep from having a hard glue joint.

Next, I cut the airfoil to fit inside the flaperon and the tip profile. I had about a 1/2 inch of the foam inside the flaperon.

Next I used the disk sander to round it to a desirable shape.

I did the final shaping with sandpaper. The size at this stage is slightly under the finished product.

To do a 1 layer fiberglass shell, I put the tips on skewers in a board to hold them for this stage.

Next was laying on the fiberglass and letting it cure.

After it cured, I trimed off the excess glass. At this stage, the weight of one tip was .4 Oz.

To adhere the tip to the flaperon I used a slurry of epoxy and microballoons thickened to peanut butter consistency, this also filled the glass weave and brought it to the desired profile. I used 20 mil plumbers tape to protect the skin of the flaperon while I shaped the cured micro down to the final shape, the filled in any low areas with SuperFill.

The finish product set aside until final prep for paint.

Victor and I were very happy with the finished product, light and sturdy.

Looks like the tips turned out very nice. I enjoy watching your build.

I has been a long time since our last update. Since then we have finished everything we could do before cover, so ... we started on covering. I did a short video on our first surface cover. Here is a link to the video on my YouTube channel. I hope you enjoy it.
