Below are the airfoils we will use for root chord and tip chord. Right click on image and download to your computer. Print at 100%. Airfoils can be laser cut if you have access to a laser machine, or simply use balsa wood, or aluminum or even cardboard to cut out the shape of the foils. In the build video i use 2mm hard balsa wood, its easy to cut with exacto knife and fairly rigid for hot wiring.
If using the emax rs1306 motor mount motor, use this motor mount to print. Trace outline and drill holes on a thin aluminum sheet or 2mm bass wood, plywood or any hard wood. You may also use an old credit card or license, its plastic and very strong.

Wing Spar & Pushrods
for the main wing spar, we use 3mm x 2mm hollow carbon fiber tube. This will provide structural strength to the wings. You are welcome to use flat carbon fiber spar, just make sure its light weight, 4mm or 5mm might be too heavy. Wooden dowels can also be used.
Pushrods are also 1.5mm carbon fiber rods. You may use thick wire if you do not have carbon fiber, but again we want to keep this wing as light as possible for maximum speed, agility and ease of flight.
Any type of foam can be used for this micro wing project. I like using XPS foam as its dense and light weight and virtually unbreakable.
The Turnigy TGY-0025 Nano Servos work great with this setup. They are only 2.5 grams of and firstname.lastname@example.orgV of torque. enough to hold your yank and banks with this fast micro wing. 5 gram servos can also be used, but taking note the more wight you add, the heavier the wing will get and torque will be lost.

Motor used for this setup is the EMAX 1306 RS1306 4000KV version
with a weight of only 10 grams, it will produce ridiculous speeds with this MicroSonic wing.

If using the motor listed above, proper propeller will be 4×4.5L You may use plastic quad copter propellers also as long as its 4×4.5
Quanum Carbon Fiber Propeller 4×4.5
Battery we will use a 450mAh 3S LiPo Battery Pack 11.1V you are welcome to use a 2s instead but this will throw off the CG ( center of gravity) unless you move the battery back. This spififict setup uses the 450mah 3s pack with a weight of 40grams. You may also use a 2s pack that has a weight of 40grams to achieve the right balance.
