I'm creating a bigger and more efficient quadcopter (for longer flying time) that can be easily disassembled (to carry). I'd like to be control from the ground station, maybe later with optical recognition by raspberry pi using opencv or tensorflow. videos about fly: [crow to reduced angle P value](https://www.youtube.com/watch?v=qqBWV4xeB7c) [crow loiter mode](https://www.youtube.com/watch?v=krTDv05QTa4) - The quadcopter weight is 1.6kg without the gimbal and battery and without raspberry pi (check the photos). - The 2 axis gimbal, 5000mAh 6S battery, and gimbal holder part, thieye t5 edge is 1kg together. According to the RC timer table, one motor can lift 1570g at 22.2V 9.6A. That is 6280g at total 22.2V. When we use 6S battery we use 25.2V as supply voltage. So this must be able to raise more than that. **2020-02-07** * Added GPS pipe holder: - pipe holders - GPS holder pipe bottom_20200206.stl - pipe holders - GPS holder pipe top_20200206.stl **2020-02-06** * Added a new flat electronic box "electronic box - box cover flat 20200203.stl". It's flat so you can put the batteries on top. (For this need a holder for the arms to hold the GPS.) I'll upload it later when I printed it and tried it. **2019-05-21:** * I'm changed the propellers from 17" to 18" and fighting with vibrations. These motors with 18x5.5 propellers can lift 1570g per engine according to the datasheet at 9.6A 22.2V. But I couldn't fly stable with it with a payload of 0.5kg, I think I installed too thin power lines wires between PDB and ESC. So I need to replace this wires too. * I cut the carbon frame arms from 50mm to 40mm this made the frame more rigid, the whole system can be handled easier, the motor-motor distance is about 74cm now. (I'm not yet fly with this new setup) * I started to design a 3 axis gimbal for crow, couse the cheap banggood gimbal is not enough stable (and it has only 2 axes). I want the gimbal be able to carry a gopro size and a nex5 size camera too. * I removed the sonar from the main electronic box and put it on one arm. I think I try to print a new electronic box cover (with vertical sides) and place the batteries on the top. Therefor I need to remove the GPS holder and put it on other arm. This whole changes allows to easily place the gimbal and other things under the frame. I'll upload the stl files later if it is flys good. But you can still export from the source files from cad.onshape.com. **2019-04-07:** * uploaded pixhawk 2.4.8, PDB, ESC and motors connection diagramm. * added electronic part assembly description text * added main BOM section * vibrations successfully eleminated from the gimbal (i'll upload the stl files later), now I can balance the motors and the propellers **2019-04-03:** **You can print it now. It can fly.** I uploaded all the files what I have now. You can check the youtube videos how it flys. I need to design the battery holder, and I think I need to remove the bottom sonar from the electronic box base and put somewhere out, to be able to put the battery nearer to center of gravity. (but i'm not sure it is neccessery) Now I try to decrease resonations coused by the motors and propellers... **2019-03-21:** Finally flying. I added a video about loiter mode. Few days and upload the final STL files. (The gimbal holder part is not ready yet. But it can fly now.) **2019-02-26:** Increased motor holder - top.stl thickness with 1mm to be more rigid. **2019-02-21:** I redesigned the motor holder, couse I dont like the cable connections. I printed one, and I think this is the final motor holder now. Uploaded this files: - motor holder - top.stl - motor holder - bottom.stl - motor holder - leg and motor cable fastener.stl - leg - leg.stl - leg - spacer.stl **2019-02-10:** Printed the electronic box base, some changes needed, so corrected the design and printed again. Now it seems good. I uploaded the latest stl. **2019-02-10:** Changed electronic box base, I think it is the final version now to fly. It was very hard and long work to get all the parts good place. I print it then start to put all the electronics inside. :) **2019-02-06:** Added: - electronic box cover with place to gps holder Updated: - electronic box base **2019-01-28:** Added: - redcon cm703 radio rx holder - APM PDB holder - replaced electronic box base (added cm703, APM PDB, replaced sonar and pdb position because the carbon pipe was near to sonar) **2019-01-21:** Added: - i2c externder holder - pixhawk 2.4.8 holder - electronix box base Electronic box base will be modified later. Now supports the following parts fastening: * pixhawk buzzer * 3dr radio telemetria (it need some modification for correct fastening) * pixhawk (flexible) fastening * PDB fastening (30mm*30mm hole distance) * GY-US42V2 sonar * I2C holder **2019-01-14:** I get out pixhawk PCB from the plastic box. It will be hold directly with the pixhawk holder, trough a silicon rubber. - Added pixhawk holder stl. **2019-01-10:** - Changed *carbon pipe fastener* to M4 screws, couse the nut head surface is bigger and when u fasten the screw it holds better. - Added *karbon pipe fastener knob* to be able to fasten with hand when disassembling/assembling. **2019-01-08:** There is a new carbon pipe fasteren. I printed the first and seems enough rigid. Uploaded the new stl file. And a photo about it. **2019-01-06:** I modifed the motor holder to cut out the side part. It is not yet printed. (The actual photos shows the old version.) **Part list:** I'm using this things things now (later i'll make it more detailed, to a full BOM): * 4x carbon pipes od: 16mm, id: 14mm, 500mm length * 4x rctimer 5010-260kv motors * 4x 1755 17X5.5 Carbon props * 4x Holybro Tekko32 F3 35A ESC * pixhawk 2.4.8 * raspberry pi 3b+ * 3dr radio telemetry * some 2 axis gimbal
