I installed a micro water pump(brushless) on my twin rigger just to improve the cooling of my esc's/motors activated by a nano servo and micro swicth and the results were impressing.Then I knew that HKing sells receiver relays swiches controlled via radio and got two of them with the purpuse to get a cleaner set up but have tried for hours to get them work with no sucess...I guess there is a miscomunication with my Futaba Faast radio...anyway if someone had sucess with these small devices let me know. Thanks in advance
