I built a 250 X racer with these motors and got a smooth 15 minute flight with a 1500 mAh graphene battery. The build weighs 270 grams without battery. I used kingkong 5040 3-blade props. These motors don't have a lot of push and are not for racers but have a high efficiency (4.4 g/W). Compared to the BR2205 they have 30% more efficiency and flight time. Ideal for flying slowly and getting long flight times. Well manufactured and balanced. They come in cardboard box, wrapped in plastic and with their corresponding screws.

I have built a 250 X racer with these motors. I get great flight times, I get 15 minutes flying slowly with a 4S graphene (1500 mAh). I used kingkong 3-blade 5040 props. My build only weighs 270 grams without battery. Well, as others said with these motors you cannot get big trust as with the BR2205 but in exchange you get a great efficiency (4.4 g/W). The 2205 only has the 70% efficiency of these 2403 motors, you can get 30% more flight time with these engines compared to the 2205. It comes in a carton box and with screws,Very satisfied

I love using this motor because it can take a beating. You do lose some power because they are so wide but that doesnt bother me since I am not flying at full throttle the whole time. These are probably best for the price. Have not been able to bend a shaft like i would do with the first racerstar motors whicher were 22XX. Since these have a shorter shaft it is harder to bend it.

These are slowly going on all my quads that can take 6" props. They're not quite as powerful as the BR2205's I'm removing, But they only draw about 75% of the power of the 2205's, So I can either use smaller/lighter/cheaper batteries, Or the same batteries and get a few more minutes flight time per pack. Unless you're racing, you don't actually use full throttle that often, So I'm personally happy to trade 15% of the power for 25% more flight time

Motors look nice, run fine with KK20A esc,s. Plenty of power and running cool. Recommended!

Amazing aerodynamic design. Exact design 2403 for QAV250 quad . Will use with 5045 prop. BR2403 is perfection from #RaceStar
