2 planes on same frequency
I ordered 2 dynam super cub pa 18s so my grandsons could learn to fly them at my place and before ordering I chatted with the "live help" at nitroplanes web site and asked if I could fly 2planes of the same model at the same time in the same area without interfering with each other frequency wise and the reply I got was when ordering to state in the comment box to have them change one of the planes frequencies and then they could both be flown. I did this and even stressed that I needed this done or I did not want to complete the order. The planes came and it appears the frequencies are the same, as one controller starts both planes. I have not flown one plane yet as I just got it assembled but I did try the same controller and both planes start up with the same controller. How can I change the frequency on one of the planes? Would have been very helpful if the comment box had been read and the request fulfilled.
Thanks to anyone for any help
