I am in the process of switching from a Spektrum DX3R to RadioPost...I am way far from being a sponsored driver so my opinion is very unbiased. I have always run JR radios in the past (still use X9503 heli radio) and Spektrum is basically JR in my opinion. Well I went to a race and run in to a an old friend who was using RadioPost. I held his transmitter and loved the way it fit my hand and the balance of it. I knew right then that was the radio for me. I have a big race this weekend in Savannah that I will still be using my DX3R for because I have not been able to get enough receivers for all the classes I will be running...but after that I will be all RadioPost and will let you know what I think after some hardcore racing.
