Ok.. the wings are back out of the shucks and the Ultimate glue did a great job expanding into every single joint!!

I still need to give it a good sanding to blend in everything smooth, but you can see the funnel holes that were made to channel in the Ultimate glue around the wing tube + the wingtube support block + the additional high-density balsa spar that the 126" Cardens now feature!

New weight is 14.3oz, so the wingtube, support block, balsa spars and glue added 2.6oz to the wing.

Next step is to make the channels in the surface of the foam to inlay the carbon fiber tow so that nothing shows through the balsa sheeting!!

I just made up a little block with some sandpaper and ran it along a straight edge - 2 swipes and I've got my 1/64" deep channels.

The servo lead tunnel has been cut out and it is routed right close to where the durant boxes will end up!!!

I will span this crack with some carbon fiber tow soon to ensure this tunnel does not cause a stress riser in the wing!

Re: ""NEW"" 126" Carden Edge 540 - Build Thread

And here is the carbon fiber tow layed ontop of the wing. I have decided to use considerably more carbon fiber on this wing versus my 40% Carden Edge due to the larger wing span and higher stresses with will come from the Mintor 220!!!

The first pictures shows the 3 lengths of 12k tow (12000 fibers in the strand). The one strand spans the servo-wire tunnel groove.

The second and third pictures show the remaining carbon fiber which is all 6k tow (6000 fibers in the strand).





Tomorrow I will wet this CF down with thinned 30min epoxy, let it cure and then flip the wing over and do the same pattern on the other side!

This wing will be stronger than steel when it's all done!!

Re: ""NEW"" 126" Carden Edge 540 - Build Thread

Yeehaa!!!

All the Carbon Fiber Tow has been laminated onto the foam cores with thinned 30-min epoxy and I`m now ready to start onto the sheeting this weekend (my honey-do list is growing, so I'll start into the sheeting Saturday)!!

Some facts.....

Weight:
Weight of each core prior to the CF Tow = 14.3oz
Weight of each core after installation of CF Tow = 16.4oz

Therefore, the CF Tow installation added 2.1oz to each wing!!!
(1.2oz is the epoxy & 0.9oz is the CF Tow)

Strength: - insanely stiff core now (changed the cores from wet noodles to surf-boards!!)

Amount of CF Tow used:
12k Tow - 45 feet
6k Tow = 62 feet

Time spent: 20 hours to core + 12 hours to layup the CF tow

Cost: Don't even go there!!! I don't want to think about the cost of 107ft of CF!!

Is it worth it? To save 3/4lb on the wings - Absolutely!!!

Re: ""NEW"" 126" Carden Edge 540 - Build Thread

I couldn't resist playing with a bit of balsa tonight!!

I got the top and bottom sheeting for one wing edge-glued. The gameplan this weekend is to sand the sheeting, lay-up the one wing and then go back and do the sheeting for the second wing to conserve space in the workshop.

Again, the wood on this kit is second to none... out-of-this-world!. Dennis hand sorts all the wood twice for each kit and it shows! The weights and grain of wood within each bundle that he separates in the kit are so close!

The weights are:
Wing balsa: 28.34grams / 48" x 3.75" x 1/16" piece
Rudder/stab medium density balsa: 23.14grams / 48" x 3.75" x 1/16" piece
Low desity balsa (t-deck, belly, hatch) 21.82grams / 48" x 3.75" x 1/16" piece

LOL!!! Have you ever stopped and thought about how many hundred options we're discussed over the phone and still can't seem to figure out the next bigger and better project for you!

Everything from an Ultralight 40% or 43% to a 35% with your 3W quad to the soon-to-be-released 40% Carden Ultimate!!!

We are sick!!!!
