Froggy 150 micro FPV racer

thingiverse

This is my final design of a compact indoor micro FPV quadcopter. It's based on previous designs, but with some new features that improve its performance and versatility:\nfits 3.5" propellers, which seem to be the best choice for an indoor quad with 1306 3100kv motors\nreinforces arms and base\nLED plates between arms in front and rear part (30x7 mm, e.g Diatone led for ZMR250 will fit this space)\nthicker spacers Froggy 150 is a micro FPV racing quad designed to be one of the smallest and lightest frames that accommodate 3.5" propellers and standard components like 1306 motors or CC3D atom flight controller board.\nYou can squeeze it through every hole :) It's easy to print & build, very funny to fly due to its size and agility.\nHere is a sample video from one of my flights: https://www.youtube.com/watch?v=_XaYZakmYcA. This frame is capable to carry HD camera for recording like Mobius/Foxeer Legend or even Gopro/SJCam.\nWe also do some indoor racing: https://www.youtube.com/watch?v=Qn6DaZgi6AA.\nWhen printed in ABS with 100% infill it's also rigid and will survive many crashes.\nThe total frame weight is about 35 grams (ABS, 100% infill, M2 self-tapping screws), AUW with FPV gear and 3s lipo 500 mAh is about 200 grams. My recommended setup includes:\nmotors: 4x 1306 3100kv (http://www.banggood.com/DYS-1306-3100KV-BX-Series-Brushless-Motor-For-Multicopter-CW-CCW-p-962149.html)\nESCs: 4x DYS SN16A (or similar size and amps) (http://www.banggood.com/ZTW-Spider-Series-18A-OPTO-ESC-With-SimonK-Oneshot-Program-p-983660.html)\nflight controller: CC3D Atom (http://www.banggood.com/OpenPilot-CC3D-Atom-Mini-CC3D-FPV-Flight-Controller-CC3D-EVO-p-970762.html)\npropeller: 3545 bullnose (buy 5030 and cut it to 3.5") (http://www.banggood.com/2-Pairs-Gemfan-3545-3_5X4_5-Inch-ABS-Propeller-Prop-CWCCW-For-Multicopter-p-1001334.html)\nbattery: 3S LiPo 500-900 mAh (http://hobbyking.com/hobbyking/store/__25505__ZIPPY_Compact_500mAh_3S_35C_Lipo_Pack.html)\nFPV camera: mini PZ0420 (or Eachine700tvl) (http://www.banggood.com/Eachine-700TVL-2_6mm-Lens-1-3-CMOS-110-Degree-FPV-Mini-Camera-p-991027.html)\nvideo TX: FT951 25mW (http://www.banggood.com/Eachine-ET25-5_8G-32CH-25mW-7-24V-Super-Light-Transmitter-p-991026.html, http://www.banggood.com/5_8G-Circular-Polarized-LHCP-Antenna-Short-SMA-RP-SMA-p-965219.html)\nThis 3S setup has very high power to weight ratio and flies really well even with HD cam.\nSoftware:\nBLHeli14.1 firmware for ESCs + Damped Light mode + Oneshot125\nCleanflight 1.10 Luxfloat controller PIDs:\nroll/pitch: 2, 0.040, 30\nyaw: 6, 0.040, 5\nlooptime: 1600 There is also a bigger version for 4" propellers (http://www.thingiverse.com/thing:1003801) and 5" propellers (http://www.thingiverse.com/thing:1069161).\nHave fun!
