This is a review of the ZMR 1804 2400kv brushless outrunner. I purchased these from www.banggood.com. They are also known by the RCX 1804 label as well. So far they have been good on my 250 quadcopter but there are some slight quality control issues but for the price they are pretty good.
The thrust test was done at the mid throttle point 50% (typical hover for a quadcopter) and at full throttle with 2 blade and 4 blade gemfan 5030 propellers. The results were interesting.
