Racerstar BR1811-3800KV 1S 2S Mini Brushless Motor for Micro Tiny FPV RC Airplane Racing Drone
A part of the review has been auto-translated.
Superb engine of a low weight and small in the hand: first photo, the whole makes 14.49 grams with propeller and "saver module." The second photo shows all the parts supplied and I added the 5030 propeller. I then mounted the cone for fixing the propeller and on the last photo we see the "saver module" holding the propeller. To protect the propeller it is interesting to use the mounting of the last photo, it will not break. For a confirmed pilot the cone makes it possible to tighten the propeller well. The engine can pull 175 grams with a 4030 under 6 amperes of current; I think it will be able to produce a thrust of 180 grams with the 5030; my electric plane weighs 180 grams fully equipped with electric and this engine. It's a good buy, and the engine has ball bearings. Note that it can work in lipo1S... Attention no allen keys provided!
Nice BL Motor,for small Planes .choose it for 2S Lipo
Great motor!!
Did not come with the bullet connectors, which is fine for me as I would have had to cut them off anyway but I have to lower the quality mark because the page shows the bullet connectors being attached. Otherwise the different shaft pieces did come with it. It also came with an O-Ring the same rough diameter of the housing, though I'm not exactly certain what it's for (I won't need it). On the test bench it sounds good and spins very stable, though I haven't put a proper load on it yet.
Great product!_Price-performance very good!
Everything ok
What ca I say? My favorite small motor.
If you like small models this one of the best power plants available. It's been around since the beginning of the BL era, so a well proven design. It turns a GWS 5X3 prop using 7.8 volts (2S) at 7.5 amps for 58 watts in.
Very good motor. Tested with AEORC E-Power 10A ESC, 5030 propeller and various 2S LiPo batteries (range of 350 mAh - 450 mAh). Weight is 16g with 5030 propeller attached by provided nut. Motor pulls 78g at 50% throttle, 160g at 100% throttle. The temperature is moderate at 50%, but gets hot at 100% throttle.
Not rested yet, I hope it will work as described.
