Back before I left for the NEAT Fair 2016.

I built a portable battery box. I wanted something I could take to the field and charge any battery back needed. I also wanted to be able to recharge the batteries with solar power.

The following is a very quick slideshow of what I came up with. The entire project was put together with spare parts and scraps.

So with the start of a new job Yesterday. My new work schedule does not allow a lot of free time for the hobby. So work on the Lady Bug will be on hold for a bit. I still want to finish it by years end. But in all honesty I don't see that happening.

Ok, Another quick video. I am sorry for it not having sound. (my first time using this webcam)

I cut the Vertical stab and rudder. I had to recut the rudder. The foam popped up and the bit hit it on the way across. The second pas went much better.

The rudder is 15.92 inches tall.

Video 1 (1 min 50 sec)

Nothing new over the last few days. Work seems to get in the way now and then.

I am working on the electronics side of things. Servo tray, motor mount, battery hatch and so on. I am also working on placement for proper CG.

I have a stack of foam waiting to be cut. New formers, top and bottom skins, rudder and vertical stabilizer.

I hope to be back in the shop later this week. If it's going to rain. Then I might as well be stuck in the shop.

Here is a quick video of my CNC machine cutting a fuse side. Nothing fancy.

Today was a semi productive day. I cut out two new fuse sides on the CNC machine. My first set were test cuts and missing the holes for the wing hold down and axel. I also modified the fuse a bit. I made it about an inch longer. I also changed the front firewall to fit the motor better.
I still need to cut doublers for inside the fuse. I want to strengthen the area around the wing hold down and axel area.
There is still a lot of things to do. I need to cut new formers with holes for the control rods to pass through. I also need to cut the vertical stab and rudder along with the top and bottom skins.
But at least it is starting to look like a plane.

I have made a little progress.

I glued all the wing ribs in place and have installed the spar. I also glued the wing tip supports on as well.

Had the CNC machine up and running this afternoon. I had previously cut the wing panels for a plane. I decided that I needed to cut a few slots to help it fold over the ribs.
I made a test cut on some scrap foam. It looked good and I was happy with how it turned out. My first cut of the left wing half went fine. The right wing half did not work out so well. I did not account for the inconsistencies of the foam. So basically it cut all the way through in a few spots.
I could have set the cut deeper but did not think it was needed with the foam so thin to begin with.
I thought about cutting the full length of the wing as one cut. I was afraid the panels would move during the cut. And I am pretty sure it will not like the blue painters tape holding it all together.
So here is my first attempt at making a large foam wing.

With a little family down time today. I decided to try and recut two more pilot figures.

With the summer break and the kids out of school. It is time for a break from the CNC machine. I am still working on drawings in Sketchup when I have time. If it is something simple that does not require a lot of machine time. I will try to cut something. I do have some cool things that I am working on.

My first attempt at cutting the pilot figure was going so well. I got down to the last 10-15 min and the bit got driven into the table. I don't believe it is the machines fault. I am fairly confident it is the program. Seeing as how it is not mine and I did not write it. I did a manual hot wire cut so I could at least remove it from the rest of the block.
Oh well, it's a start.

WOW, what a difference a few bearings make. (15 in all) I can not believe how smooth the movement is now.

I had a small issue removing the mill head from the gantry. After that the job went smoothly. No where near as bad as I thought it would be. After each axis was upgraded. I rebooted the machine and did a test jog. I learned a lesson a long time ago. Only make 1 change at a time.

The only thing that changed was I needed to readjust a limit switch on the V carriage assembly. I must have bumped it or something. After a quick readjust, I rehomed the machine. Smooth, that's all I can say. A lot quieter as well. I have a small issue with the W tower. but I am confident it will be a quick fix.

I hope to be up and running by Tuesday of this week.

After some deep thought. We have decided to upgrade some parts on my CNC machine. I am changing the idler pulleys from bushing to full bearings. The manufacturer came to the decision that the bushing idlers might be binding. So this weekend I will be swapping out some parts. I hope to be up and running next week.

Well work has stopped on my big foamy. I am having an issue with my CNC machine.
So for now I am working with the manufacture guy to find and solve the problem.

I forgot to mention. I did cut out some wheels as well. I will be putting the fuse back on the bed and cut holes for the axel. I also need to cut some parts for inside the fuse.

Now that the holidays are over with. I have made a little more progress. I have cut the wing ribs and wing. I have also cut the horizontal stab and elevator.
I still need to cut the top and bottom skins. I also need to cut the rudder and vertical stabilizer. Some where I need to decided on a windshield for it.

This is going to be BIG.........

It is 39.0 inches long, 13.0 tall and 5.5 wide at F-1. I have it taped together just for the picture. Nothing is final yet.

I am excited to see how this plays out. So far it is looking good.

I have always wanted to make a flat wing with ailerons for a Grasshopper.

The original plane is a 2 ch plane with a polyhedral wing. I never did get mine to fly very well. I hope by making it a 4 ch plane it will fly better.

The original wing is in the 43 inch range. This wing "being the first test cut" is 50 inches. My next step will be adding the wing tip cut paths along with the aileron and servo pockets. I want to round the tips and shorten it to 43 inches.

"It looks ridiculous with this giant wing".

After some small set backs. I have my CNC hot wire/router up and running.

I had a few extra steps to learn and adjust to for the hot wire. Never the less it works. I am happy to finally have it up and cutting. Nothing is completely perfect yet. It is a learning experience.

I am having fun.

So it has been quite a while sense I have been here.
I spend most o my time on FB. Seems easier to stay in touch with my RC friends.
I still fly, although not as much as I would like. Life seems to get in the way of that. I still build off the wall planes. I enjoy showing up with the strange looking plans. I am now moving into the world of CNC. It should make scratch building planes easier. I am also thinking about a specific plane. I very large plane.
Regaurdless, I am still having lots of fun. Even if I don't stop by RCG as much as I used to.
