I recently upgraded my six-rotor UAV. In order to improve flight efficiency, I specially refitted larger blades. But when it was installed, I tested it and found a series of problems. Firstly, the…Continue

"Although this technology could provide significant improvements in nearly every industry, just as with any new technology, there are downsides and disadvantages. For example, even though tethered drones could improve operational reach in the U.S.…"

Tethered technology has become an important part of uavs

Recently, I have noticed that police in many countries are using drones to conduct aerial duty, taking photos of illegal vehicles and, of course, installing loudspeakers to notify illegal drivers remotely. Of course, there is one technology that has to be mentioned, and that is the tethered device, which is the source of power for this air enforcer. Cirrutitan is the most cost-effective tear-down device as it supports MMC's most widely used UAVs.The systems not only are powered over the tether,…See More

Adams Smith replied to Nelson Campbell's discussion Electricity is very hot what's going on
"Motor heating reasons are many, maybe heat dissipation is not good, or the wire voltage is too high. But if this condition is after the blade replacement, it should be motor and blade do not match."

"Your motor and prop combo didn't match. I use a lot of large blades on multirotor, the are indeed very efficient but the most important thing is to make sure the motor KV value and torque must match the prop blades requirements. High KV motor…"

"If the ONLY thing you changed in the upgrade, was the size of the propellers, it may be they are too large for the motors.  What voltage, motor, ESC, and props are you using and how much is the total weight of the UAV?  Can you put the…"

I recently upgraded my six-rotor UAV. In order to improve flight efficiency, I specially refitted larger blades. But when it was installed, I tested it and found a series of problems. Firstly, the electric power is very hot, and secondly, it is obvious that the thrust of propeller is getting smaller and smaller. Can someone tell me why?See More

Nelson Campbell replied to John warrior's discussion NIFFER G2 transmits detection data in real time. What do you think?
"It looks very cool, but as far as I know, the DJI M600 Pro is sold as a complete set, not as a retail accessory"

"It's only -20℃. Is that a joke? In many northern cities, it's -30° in winter."

Nelson Campbell replied to Stanley Wilson's discussion Homemade uav detection! What kind of equipment is needed
"First, you need to make sure the instrument can be attached to your drone. Secondly, the most important detection devices are sensors and cameras. You can search for the details of this product."
