Author: Unknown I used to be a Castle only fan until I tried these controllers out and they are an excellent buy at a fraction of a Castle 80's cost. The fact that I no longer need to run a separate BEC for applications requiring 4s-6s just makes me a even bigger fan!!!
Author: Unknown Bought this to replace my damaged CC 60 amp ESC at about a third of the replacement price and haven't regretted it. Also allowed me to dispose of the separate UBEC since it has a switch mode BEC built in - great! I did find that I had to set the Timing to High as recommended in the instructions to suit my big Himax outrunner (HC5018-530 on 6S Polyquests, 21.8volts @ 57 amps giving 1362 watts static on 13x6.5 APC-E)
This is a very handy little gadget, although it is a bit pricey. It's more convenient to use on electric motors than an optical RPM meter and also good for revealing the actual kv of motors. On some motors I have measured a significant difference from the manufacturer's claimed kv with this device
