AnnMarie,
Thanks so much for your fast response. Did you say that the 148DF is better? What about the 127DP? I have located one each of these here on RCU for $75 each. One of them is on my channel 58. Right now, my transmitter is working perfectly flying my other plane, with no range problems. Do you think that it is really important to have it checked out once a year? Please reply. Thanks
