i teamed up with my good friend and project ace Luis Struffaldi and we came up with this Jig

designed for general building of wings and fuselage, works for C/L and R/C as well!

we have laser cut from MDF (fiber board) 1/4. the base is cut in 3 parts, you have to glue them for shipping purposes

dimensions are 27" x 72" long. you can built pratically any C/L model wing easily, as well as fuselage.

same applies to R/C , and if the builder follows our instructions, even bigger planes are ok

Model shown is a 25 sized stunt

the sliders can be adjusted for almost any LE and TE shapes

notches are for rubber bands to hold sticks tight

once you finished one side of the wing, you can flip it over and sheet the other side without distorting anything

well thought out jig.

Fred,

Excellent engineering and construction as usual. I wouldn't expect anything less from your office. 

I hate building wings, if I had a few extra bucks, your wing jig could cure me of that.

See how things go.

Again, congratulations on your efforts and fine results.

I don't know about getting to Fred's level, because I have never seen anything like one of his planes (they are unbelievable!), but a jig - any jig for that matter - will definitely improve your game. I can attest to that personally.

I gave our first prototype to a very good friend of mine that had never built a larger (bigger than 25 size) plane and we set out to assemble a couple of PROMO 40 (something like a Twister).

We took maybe half an hour to 45 minutes to put the jig together, check dimensions and alignments. After that, it was a quick job to position the parts and glue everything. Best of all, just popped the wing out and started positioning the parts for the second one. In less than 3 hours we had 2 wings ready and, best of all, they were STRAIGHT!

Check the photos!

Luis, you´re a gentlemen! thanks for the words
he´s great on the projects, i can assure you all!
and yes, the Jig makes building wings almost fool proof
you really need to be sloppy or drunk to warp a wing or fuse with it
