So I need some opinions here. I have a Matrix Truggy and Buggy. I am ABOUT to go 2.4ghz. I have my eye on the SPEKTRUM DX3.0 so I can run the same transmitter for both of my rigs with the two included receivers. I am barely into club racing at a local track but looking to take my cars to a couple of races this summer. Is this radio sytem a good idea or is it obsolete. I know there are more expensive radio systems out there but I am trying to go for a good radio system that is crystal free that might work for both of my cars. I have also looked at the FUTABA 2.4 system but that one is a little pricier and includes just one receiver... What do you guys think? Thanks.
