TinyWing - Brushless 40cm FPV Wing

thingiverse

Having been inspired by [drcameron's design](https://www.thingiverse.com/thing:2781182), I wanted to try to design my own micro wing in which to fit components that I had at hand. ### Specs + 40cm wingspan + Smoothed KFm-3 airfoil. + Fits 2" props + Optionally fits FPV stuff. + 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 coloured)_. + 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](https://www.getfpv.com/gemfan-hulkie-blue-2040-durable-3-blade-set-of-8-4cw-4ccw.html))_ + **1x** Smallest brushless ESC you can find <i>(I'm using a [20A from Armattan](https://www.armattanquads.com/armattan-dshot-20-amps-blheli_s-esc-bb2-4-pieces/))</i>. + **1x** Micro 5V BEC _(like [this one from Matek](http://www.mateksys.com/?portfolio=mbec6s))_. + **2x** 9g _(or 7.6g)_ servos. + **1x** FPV Cam + VTX _(something like [this](https://www.banggood.com/Eachine-E010C-E010S-Spare-Part-p-1119217.html) 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](https://github.com/iNavFlight/inav/wiki/Supported-boards))_. + Serial RX of your choice _(I'm using an [FrSky R-XSR](https://www.frsky-rc.com/product/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](https://www.frsky-rc.com/product/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)
