Hello everybody, I am a newbie into the world of UAVs/multicopters and after reading and reading a lot of stuff and useful information I need to start sorting things out inside my head. Therefore, I need the help of the experienced guys to make sure that I am heading to the right direction. I hope …

Regarding the speed and flight time, I do not expect to have a quadcopter that flies with 100km/h for 25 minutes continuously. I just mean that it should be able to follow a fast moving object with 100km/h for 1 minute maximum and then continue flying with more normal speeds of lets say 20km/h for t…

Hey, usually to fly fast, you need powerful motors with use a lot of battery. But to get good flight times you need carefully selected motors that are efficient. It’s not impossible to combine both but its all about compromise between speed and efficiency. So its possible to build a 100km+ quadcop…

Thank for your answer, i will do my research and i will come back to you with the parts I decided to buy… and then you could guide me if my combination choice is correct and will fullfill my quadcopter requirements… Regarding the flight range, of course i dont plan to use my quad for commercial pu…

Dear Unmannedtech, after some days of reading and research regarding quadcopters and their theory, I have decided to use the following configuration: DJI Flamewheel F450 frame ESC E-Max BLHeli 30A OPTO DJI 2212-920KV Gnauper E Prop 9*5 LiPo 10000mAh 15/30C 4S1P CC3D or Naze32 Acro flight …

Hi All your options seem great except for the battery as I think it might be abit too heavy. What is the weight of the battery you plan to use? In terms of the motors, I beleive the ones you are using will produce around 600g of thrust each, and when building a quadcopter you want to be able to h…

Dear UnmannedTech, the battery i plan to use weighs 800g and it is 10000mAh 4S1P… I tested my combination using ecalc.ch tool, and in the attached image you can see the results… According, to ecalc it seems that there is no problem… I mean the speed is quite fast, and the flight times good… I woul…

If thats what it says on Ecalc maybe I am gettting wrong thrust values on your motors (we dont sell them so I am not sure about actual thrust values) But if you have the thrust specs please post them so I can check. However one thing I did notice on your screenshot is that its saying the battey we…

Let me find the thrust values now and i will post them now immediately… Regarding battery weight, the weight you see is the weight of one cell… If you multiply it by 4 it gives 876g…and it is also shown in the bottom under the remarks section for the batery… However, as i told you the battery i fou…

Thanks for pointing out the battery weight on ecalc :stuck_out_tongue: its been a long day :tired_face: Also according to the thrust results on the RC groups page you posted with a 4s setup and a similar size prop its showing only 330g of thrust at 50% and 636g at 75%. So the absolute maximum takeo…

THen maybe, i will try to find another motor which will have about the same KV (920) but more thrust and hopefully more Watts as well… I am happy that I almost finalized my basic parts selection… However, I think I will need some help as well regarding the Radio equipment according to my needs… Th…
