  • Flight Controller Soft Mount – is it worth it?

    Is it worth to soft mount flight controller? Are gyro pads I recommended here better than rubber standoffs? I feel that they are better, but I do not have any solid data to prove it. So I can only tell, that I find them better and that is all. But, I can answer the question…

  • DIY brushless motor kit – I give up, for now…

    Latest update on the topic of DIY motor kit from Banggood (DIY Assemble 2204 2-3S Brushless Motor 0.42*2.8 Copper Wire with Motor Cap Banana Plug): I give up. For now, at least. In total, I tried to wind this motor 6 times. In every single case it ended in the same way: one of the…

  • DIY brushless motor kit – first failure

    Just like it was expected, my first attempt to wind a brushless motor (12N14P) was a failure. Probable cause: short circuit between phases and my creation released magic smoke. Then I tried for a second time, and failed again. This time less, no smoke, but motor overheats and does not want to start most of…

  • DIY brushless motor kit…

    China is such a magical place… among all those affordable things you can buy there, there are those not so useful, but still affordable things that, for sure, you do not need. Just like DIY Assemble 2204 2-3S Brushless Motor 0.42*2.8 Copper Wire with Motor Cap Banana Plug. As you can see on a picture…

  • How to reverse motor direction

    You finished your build, you connect LiPo, power up flight controller, apply throttle (no propellers of course) and you see that one or motors are spinning in wrong direction. How to fix that? You can not do it, for example in Cleanflight Configurator. ESC communication protocol does not allow to change BLC motor direction. There…

  • Damaged motor: broken off magnet

    One of the things that can happen to brushless motors, specially outrunners, is broken off magnet. Stronger crash, or even extensive vibrations, can cause one one small magnets located in motors bell to tear off. After all, they are only glued to rotating part of motor. Symptoms are: If magnet stays inside motor, it will…

  • Quick review: Turnigy 2730 1500KV brushless motor

    I’ve bought first Turnigy 2730 1500KV brushless motor by accident. I needed something small and cheap for Depron airboat. Then I needed something similar for a Depron airplane. At the end, in 6 months, I owned 3 T2730 1500KV motors. Not all of them survived the experience. One got lost in the middle of a lake…

  • Quick Review: EMAX GT2218/08 1100KV motors

    Since I was lacking some power in my Reptile 500 quadcopter, I was considering switching my Turnigy MT2213 935KV motors to something more powerful. Last previous weekend kind of forced me to make that switch: I destroyed one motor while trying to replace bearings. Being forced with lack of motors I’ve decided to stay with…

  • Let’s build a FPV drone: motors and electronics

    My 250 class quadcopter project is slowly coming to a successful (hopefully) end. Finally had some time to assemble motors and ESC. Since I wanted to have rather standard setup with 5×3 propellers, I had no super high demand on ESC, I’ve decided to use Turnigy Multistar 10A V2 ESC preflashed with BLHeli software available at Hobby King.…
