I switched from Futaba 3PKs to the Spektrum DX3R because of the lighter weight.

I was having issues with my hand going numb from holding that heavy Futaba, switching to the DX3R got me to the end of the main without any hand issues, for a while. I had carpal tunnel syndrome and finally had surgery after a few years. I still like the Spektrum radios and feel they are an excellent value for the money.
