Remix Micro 105 FPV Quadcopter

thingiverse

This is my remix of punkkills excellent Micro 105 FPV Quadcopter. http://www.thingiverse.com/thing:1221911 punkkills also gives credit to the FireFlo V2 and the Alpine Drones Micro H. The frame is light and fairly stiff printed with ABS. The main frame tubes are hollow extrusions and print hollow with fill set to 100%. There are raised mounting perches provided for the Micro-Scisky Flight Control Board. They raise the board for USB access without having to notch the frame. The board is placed on the mounts and then the mounts are melted over the corners of the board with a flat tip in a soldering gun (I have been adding a small bit of ABS to the tip to help fill the corner). There are two tops provided. The first fits the FX758-2 5.8G 200mW Video Transmitter (http://bit.ly/1SZvaAB) and 170 Degree Wide Angle Camera (http://bit.ly/1WhNkmX). The transmitter clips into the frame and provides clearance for the straight wire antenna between the transmitter and the frame. The camera snaps into the front of the frame. The stand offs are partially tapped with 4-40 threads. The top section is attached to the frame with (4) 4-40 x 1/4" button socket head screws. The other top fits the Quanum Elite TX Camera Combo (http://www.hobbyking.com/hobbyking/store/__89777__Quanum_ELITE_TX_CAMERA_COMBO_Micro_Cam_VTX_25mW_40CH_5_8GHz_NTSC_.html) . It may hold just being snapped in but I am using a rubber band for added security (a zip tie would work as well). The left front standoff will require a little post processing to clear a chip on the back of the camera. Both front standoffs may require some cleanup so to fit the bottom of the camera securely. It is also attached with the 4-40 screws. Everything else is pretty much per punkkills build links. A few additional comments: Batteries - I found these batteries on Amazon (https://www.amazon.com/dp/B01581AVTA/ref=sr_ph?ie=UTF8&qid=1467063313&sr=1&keywords=720mah). Much quicker and cheaper shipping than Hobbyking. Polarity is correct as well. I time my flights to 5 min. and these discharge to about 3.8 volts leaving a nice safety cushion to get back with. The Elite might draw less power than the separate camera/TX setup but I have not tested it. I am using the wiring adapter that came with the Quanum Elite but a gram could be saved by soldering the camera directly to the controller board. There are some slight horizontal lines in the video with the Elite so I tried the camera with a separate battery for power but I did not see any improvement in video quality. The better antenna on the Elite seems to give me slightly better range than the separate camera/TX setup. At first I was running a slightly longer antenna (about 16mm) and it seemed to work a little better. I shortened it up for testing to get it closer to 12.8mm and range was reduced. It may be the wire diameter (I am using .8mm). Additional testing is in order. I need to do a cloverleaf antenna. The Elite is sketchy on a low level pass through the back yard (standing in the front). I would not try it at all with the separate camera/TX setup. It could also be the FPV headset. I am using the Eachine VR-007. It may be affecting range as well. I don't have anything to compare it to. Print Settings Printer Brand: LulzBot Printer: Mini Rafts: No Supports: No Infill: 100% Notes: Print at 100% infill. The tubes are modeled hollow and should print that way Post-Printing Top Finishing Some finishing may be required for the Elite version of the top.
