Tough_Enough 3" HD
Description
**NOT FOR COMMERCIAL USE** I am into the R/C hobby for 25Y and I have flow anything from sailplanes to 3D helicopters and since 3Y I am addicted to FPV flying. As I moved to the digital DJI FPV system I was looking for new frames that are light, agile and built around the Caddx Vista. I decided to cut my own frame for the first time and I began to draw a 3" freestyle frame in Fusion360. In the middle of it I have seen videos of the great flying TorqueFPV Hornet HD. Inspired by this frame - not available in Europe at the moment - I finalized the design of my backyard rocket ;-) **GOALS of the project:** * 3inch "Toothpick" design with rather thin arms * built around the Caddx Vista * ability to use 2.4GHz receivers with 2 antennas * high durability and stiffness for its size/low weight * use of an FC/ESC AIO board * motors in 1404 size with at least 4,500kV, 9mm diameter mounting M2 * frame has to protect the motors from front, back and side impacts * full protection of the Vista HD camera in the TPU housing w/o having it in view * weight of around 190 gramms * and lots of power with a 4s battery 450mAh Well the result is the **Tough_Enough 3" HD** frame in its version 1.0 **PARTS needed to be cut and 3D printed:** * Bottom_Plate: 3mm Carbon 3k (UD layers in between), Arms have to be in line with UD layers! * Top_Plate: 1.5mm Carbon 3k * Cameraholder, Antennaholder, Elastic Band are printed in TPU (I used SainSmart TPU transparent violet) - Antennaholder and Camerholder need supports **Everything else you need to complete the frame:** * 4 standoffs aluminium M2 ,height 22mm, outer diameter 3.5mm (I used those from iFlight) A lot of M2 Buttonhead screws: * 8x M2x6mm for the frame to the standoffs * 4x M2x12mm for the mount of the AIO FC * 4x M2x16mm to mount the Caddx Vista (I have cut longer screws) * 8x M2 nuts secured with loctite medium (blue) * antenna tubes diameter of 3mm * Sticky pad stripes 2x 50mmx9mm (3M or Ummagrip) **The rest of my setup - for inspiration:** * 4x iFlight XING 1404 4,600kv * 1x Caddx Vista * 1x HIFIONRC F7 AIO 25A Toothpick FC/ESC Board * 1x Frsky RXSR receiver * 4x HQ Props HeadsUp Tinny 3x1.8x3 (awful colors, but provide good, linear control) * Battery CNHL 4s 450mAh 70C I hope I covered everything. Let me know if you need any small changes (e.g. hole pattern motors) or cut / printed parts (Europe).
