BOTH ... visual reasons & weight reduction ,the design is similar to other wings of high cost an caliper ,
Step 1. have the cad work done
Step 2. get the structural design and what size material should be used ,right now it,s specked out to be power coated .25 / 1/4" or 3/8" Aluminum plate ,with a weld on top mount to inside and a bottom foot ,that,s in the picture
Step 3. cut and make them .... THE SLOTTED WHOLES ARE ROUND ON THE ENDS ,me and my exact o knife was not good enough to get those correct
Please give me your idea,s
the one that is close to this design is running around Japan
