For smaller cord wings I set them further forward in the jig to bake to bake them.

Check your Pennysaver magazines or Craigslist ads. A lot of times you can find folks who'd rather replace an appliance than fix it, and you might see an oven with a broken heating element that you can get for dirt cheap (or even free) and fix yourself.

Hi folks:

I am trying to find the BB 42 in. FULL 1 PAGE non-KFm plans. That is, I wish to build the wing version with the 'under-cambered' wing.

I have found the tiled version, which are referred to in several places as the full, one page plans. I am aware of jackerbes post which lists all of the pertinent posts.

Because they man no longer be in this thread I also ask for someone who has a copy of the BB 42 in. FULL plans to email them to me.

Please help me out.

Thanks,
- Jim

As far as I know there never was any such thing as a full one page BB 42 UC wing plan. If there was, I am unaware of it. If you find itlet me know where it is and I'll add it to that list of plans.

So if you cannot get what you need from that tiled BB 42 plan that tuppertn posted there I can't help you.

The outline of the UC wing was the same as is the KFm3 wing. If you are just trying to cut a piece of foam to the size and shape of the UC wing the plan view of the KFm3 wing will give you that.

As you probably read, the 42" UC wing was considered too weak. Springer's post on turning it into a KFC wing has worked for some for making a stronger 42" UC wing:

Good luck with it, if you can find the plan send me a link to it.

Here is an enlargement I made from the 33" drawings, for use with a 2" monoblock. It should print to A0 size.

If posting the enlarged drawing is a no-no, I apologise in advance. Tony or somebody else please just say so and I'll remove it.

I personally know tony and he would not mind if it helps everyone. The poor guy has been busier than a one legged man in a butt kicking contest with the Canadian gov't doing some lobbying

Brian,
I also added reference lines inside the jig for repeatable placement.

Heading out with my niece in a bit to try and maiden her Blu-Baby with newly reinforced and hopefully totally non-foldable wings. Wish us luck.

Brian,
The jig is ridged so it's shape is not adjustable. But with wings that have a chord less than that of the jig you can adjust the curvature by moving the wing forward (more curve) or rearward where the curvearture is less. You can also bake in some washout by placing the wing tip more rearward in the jig. That gives you more chamber in the center of the wing and less at the tip. It's a marvelous jig, and you will quickly learn to place the foam in just the right place to get the desired results. 'cause if you don't you will have some undesireable charactistics in your wings! One thing we have all learned the hard way is you need to take care to make one right and one left wing section. When you don't you feel pretty silly.

Well, it flies! Everything went fine until somebody dumb-thumbed it into a car. No damage, though.

Nice video! I like the close in flying back and forth, it really shows the plane off nicely. Congratulations on the successful remaiden.

Of course, that's where it all went terribly, terribly wrong.
