This is a very handy little device doubles as your splitter to each gear unit, plus, it allows you to extend or retract the gear without the need for your transmitter. Simply apply power and press the button on the Smart Controller for cycling the gear. This is perfect for bench testing or when you're at the field and have already put your transmitter away for the day.
Voltage range: 4.8-8.4V
*Color may vary
Simply saves having to get your TX out just to raise/lower the retracts when transporting, etc.after the first few cycles it would no longer cycle the gear. Tried plugging in the power on and off and then it would finally allow cycling ...... Then the problem started all over again requiring powering off and on till it worked a few more times. Reported this to HK and they wanted me to send them a short video and pictures ... Well sorry I wasn't about to run out and buy a video camera for that. Just unbelievable . Returns would cost me twice what it was worth. Asked for credit not refund..... Nothing yet a month later..... I guess they want to make it difficult so you ignore the issue. Not happy.
