I’m new to this. I’m in the medical field, and I need a hobby. So I decided to build a drone. A big drone. I’m going to build an octocopter that can carry me. If you have some suggestions, please let me know.
This size machine has been built and is working toward commercial operation. I’m just looking for one I can call an experimental and fly in it on clear days. The SureFly has been my inspiration. It looks as if they are using a BMW range extender engine to power the system as a hybrid machine. The SureFly also has a small battery pack that gives the craft 5 min of flying time if there is an engine failure. They want to sell this for about 200K. I can’t afford that, besides, it would be more fun to build it.
As I work to learn more about this, I recognize that I have multiple knowledge deficits. My hope is that I can come to this forum and ask some questions. I’m not looking for you to do the math for me, but perhaps give insight on where to go to learn specific skills sets and areas of knowledge.
For example, I’m uncertain of the amount of power I need to operate the motors. I’m looking at the highest powered brushless motors I can find and I can see multiple energy specifications listed. But I’m not certain which translates into determining the max power I need for 8 motors on this machine. The range extender engine provides 25 kW. I need to better understand how to make this calculations and how to convert the power from the range extender to the motors without blowing out any electronics. As I said, I’m not looking for anyone to do my math, just perhaps direct me to an area where I can learn what I need to know. Specifically, which specification listed on motors will provide me with the numbers I need to know to calculate if I have enough power with the BMW motor. I suspect that if SureFly can power with the BMW motor, I should be able to do the same.
Furthermore, while I am looking at numerous brushless motors, does anyone have any suggestions for which brushless motors might be the best for this project?
I’m certain I will have many other questions. I appreciate any assistance and moral support I can obtain.
