As Steve has worked so hard to provide this facility, I thought it would only be right to try and use it. Please bear with me while I get used to it.

The building of a Wolf... 10 months 1 week ago #43

There is a little history to this build, so once again please bear with me.

A couple of years back, in a moment of weakness at a club auction, I bought a part built West Wings Skylark 1. When I got it home I found one wing had dihedral and the other one had anhedral. Neither of them had any shear webs. After some attempts to straighten them, I binned the lot, and bought a new kit. I built the kit complete with a tow release. (I like aerotowing in case you had not noticed) The whole glider only weighed 29 ounces, so I put a tow release in a Wot4 foamy that I had and figured that would tow it up. Glider set on one Tx, and tug set one another Tx, I then found a major problem. I could not tow my own glider up.....

My main flying buddies Chris Williams and his mate Geoff “Motley” Crew, both fly mode 1 and I fly mode 2, so that did not help much. On the up side Chris and I both use the FrSky Taranis transmitter, so next time we went flying I borrowed his TX, when he was not looking and put the program into it for the tug.

I got the glider tug and towline all out and setup, Chris, realized my problem and rather smugly asked “Well who is going to fly the tug then?”. I handed him his Tx, and replied “You are”...

Quick as a flash, he handed the Tx to Geoff, grabbed his camera and shot off down the field with a promise of photos. We had great fun that day, and Chris did fly the tug later on.

About a couple of days later I got an email with the basic outline of the Wolf, to 1/7th scale, and about 4 weeks later it was ready to fly. (Don't you just hate peole like that?) It turned out to be about 8 oz heavier than my Skylark, as it needed lead in the front to balance it.

So having just finished a 2 year build of my Berglalke 4, I decided to build something a little smaller.

The challenge is, to build it lighter than Chris's, and to fit spoilers, which his does not have.

More to follow soon.

Now to try and add a photo or two.

The first part was to produce a section of wing, to see if I could indeed fit a servo to operate a spoiler. I also wanted to see if 1/64" ply could be used in place of 1/16" balsa sheeting.

Well, the answer seemed to be yes in both cases, so off I went to the drawing board.

Actually to the drawing computer. This is for two reasons. Chris draws his plans to be cut out by hand, and I cannot cut out balsa and play parts to save my life. So the PDF plan gets inserted into Draftsight, and re-drawn for laser cutting. Sent off to the laser man, and I end up with nice kit of parts, which mostly fit together well. There is the odd bit or re-design as the assembly goes on.

If I had known that I was going to write this, I would have taken more photos. This is the start of the fuz. 0.8mm ply sides, 1.6mm formers, other than the 3 that hold the wing, which are 2mm. All glued with PVA wood glue, as I get affected by Cyano fumes.

Hi Barry
Thanks for contributing here. I note that you attached images and they can be viewed of course, but I wondered if it were your intention to include within the main posting. If so, there's an extra step. When posting, attach the image, as you have indeed done, and then select "Insert" for that image. You can edit and do the same subsequently. I've taken the liberty of inserting your images into one of your prior posts, but feel free to "uninsert" it. Just edit the post and remove the line of code at the insertion point that starts with "Attachment"
Cheers
Steve
