Recently Racerstar released new 6mm stator sized motor BR0603C and now they are releasing its bigger brother BR0703C. It also comes in higher KV ratings – 17000KV, 19000KV, 22000KV and also has shaft fixed with two e-clips instead of hard pressing or laser welding. This ensures that motor bell will not slipp prom the shaft. Another differencied from the previous versions: motor mount pattern is 6.6mm instead of 5.5 mm, mounting screw size is 1.4mm instead of 1.6mm. Motor weight has increased from 1.9 to 2.2 grams due to the bigger base, thicker shaft , e-clips and etc.
The good news it is almost 30% cheaper then its predecessor BR0703B motor! But how good are they? Stay tuned for the thrust tests of this motor!
