My experience with customer service has been great so far as well. I had the gears strip out on one of the mains after only a few cycles. Maria answered my email next day and had a new gear motor at my house in two days. The problem is fixed and customer service is as good as it gets in my opinion.
I have not used the gear in the plane yet since it is winter here but the operation of the controller, gear, and brakes on the bench is very smooth. The gear and controller are very high quality and I am looking forward to using them this summer.
