TinyWing - Brushless 40cm FPV Wing

thingiverse

Having been inspired by DRCameron's design, I wanted to try designing my own micro wing in which to fit components that I had available. ### Specs + 40cm wingspan + Smoothed KFm-3 airfoil. + Fits 2" props + Optionally fits FPV gear. + CG @ 64mm from nose (20% MAC). + Stall speed is ~25 km/h with a 113g AUW. ### Materials/Components needed + Wide packing tape _(clear or brightly colored)_. + CA glue _(and activator spray if possible)_. + **1x** 110x size brushless motor _(1104 preferred, but an 1106 could work too)_. + **1x** 2" propeller _(such as the Gemfan Hulkie 2040)_. + **1x** Smallest brushless ESC you can find <i>(I'm using a 20A from Armattan)</i>. + **1x** Micro 5V BEC _(like this one from Matek)_. + **2x** 9g _(or 7.6g)_ servos. + **1x** FPV Cam + VTX _(something like this has pretty crappy quality but is lightweight)_. + **1x** [3S 450mAh LiPo](https://hobbyking.com/en_us/turnigy-nano-tech-450mah-3s-65c-lipo-e-flite-compatible-blade-180cfx-eflb4503sj30.html). > #### If you want to use an FC + 20x20mm FC compatible with your firmware of choice _(possibly one supported by iNav)_. + Serial RX of your choice _(I'm using an FrSky R-XSR)_. > #### If you don't want to use an FC + PWM RX of your choice _(should be small and have at least 3 PWM outputs, the FrSky RX4R should be plenty)_. **EDIT 8 Jan 2019:** The control horn was missing! I've uploaded it. [OnShape document source](https://cad.onshape.com/documents/d52fb0cb12a9d8e877aabc30/w/be659bb2abeec31ffa525b80/e/1d064d6618aea0295240b0fa)
