Kangke Cap is not that light. With a Saito 180 it weighs 12 lb. With Moki 180 it weighs 13 lb. A CF gear, light spinner, remove pants, & light servos would save a a few oz, and possibly get it down to 11.5 lb. But still, it doesn't come w/ quality hardware like the Cap X. I got it from eBay for $250 last year. I wouldn't pay over $300 for the Kangke Cap.
