A new range of high quality, low-cost speed controllers that are impressing fliers whenever they are tried. The Hifei controllers are breaking all price barriers for locally sourced and supported ESCs. And that's a significant point - they might not cost a great deal, but you are guaranteed local support if you need it. Try asking a question about an ESC offered by an overseas company!

Hifei controllers are small, light and they work. There is a large range, including the King Kong data-logging range, but I am starting with the standard offering - and I am impressed with them as I try them out myself. These are microprocessor controlled, low resistance and programmable units. Programming is by a card that is purchased separately (see large image below) - buy one and you will have it for multiple units - no new programmer supplied with each unit, thus keeping the cost down. Supply your own connectors as well - most of us do - and this saves cost as well. The programming is the EASIEST I have ever used - set the Dill switches, plug in the ESC, connect to a motor and a battery and press a button - hey presto, it is done. You can also program with the Tx using beeps in the traditional manner if you wish.

Hifei controllers offer current limiting and thermal protection - an LED flashes if current or heat protection is activated. A safe "power on" feature ensures that your motor will not arm accidentally. If you lose radio contact for more than 3 seconds, the ESC will shut down. If radio contact is re-established, lower the throttle to activate again and restart the motor. Connect your ESC with too much voltage and the ESC also shuts down instead of going up in smoke. Try one and be convinced.
Programming options (default in bold):

1. Hard or soft cut-off
2. Governor mode - auto, low or high
3. Brake type - none, soft or hard
4. Low voltage cut-off: Auto LiPo detect, or manual 2-12 LiPo and some voltage selections
5. Switching rate - 8KHz, 12 KHz or 16 KHz
6. Start-up type: Very soft, soft or fast
7. Timing advance: auto setting, high, middle or low
8. Current limiting: Sensitive, standard, insensitive or disabled

You can see that, if you do not want to activate the brake, you can just accept the default settings and automatic detection features and go and fly!
