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
