I have both an EZRun 18amp and a Sidewinder Micro esc, and a Castle 5400kv and noname (bought from Hobbycity) 6200kv bl motor.

I like the EZRun esc better than the Sidewinder in all respects except for very slow speeds it seems to cog more than the Sidewinder which rarely does. The EZrun is more programmable, plus I have the programming card which is extremely easy/quick to use, just plug it in and go through the options.

The Castle motor is lightyears ahead of the noname though. It runs cool, smooth, etc while the Hobbycity motor runs extremely hot even with no load. I had to set the timing down to 0degrees and gear down to 12/60 to make it run cool enough to survive while i run the Castle at 15degrees and 15/60 and have no heat issues at all and it's faster/quicker.

I'm currently running the EZRun esc with the Castle motor with the others being my backups.

I took the Hobbycity motor apart to see if there was a problem inside and the windings are very wavy/inconsistent, just seems like they jammed as much wire in as they could without worrying about it being efficient. http://www.hobbycity.com/hobbycity/s...idProduct=4213
