The RubberQuads 2-5 is a 1303(.2) 6000Kv brushless motor thats designed to deliver about 300g thrust on 3S wich is perfect for a heavier (digital) 3" bibladed toothpick (150-200g). Since we where looking to achieve 350g-400g to give our little hedgehog a reasonable amount of power we desided to run it with a low-pitch 2.5"triblade on 4S and it works like expected. Please dont put a heavier prop (4-7 blade) on it when you run it on 4S since that would risk burning the motor
