To be or not to be..
Well, I guess its up to individual preference when it comes to TX. Spektrum provides all the technology at low prices. Quite a bang for your buck. So far no complaints about the DX3R or DX3S.
So how about the DX3.0 and DX2.0. I see a lot of drivers using these TXs. I'm sure there should work great too right? The thing about Spektrum is they give a lot of freebies that come along with the package. Really value for money.
As Bro Thangmo said is true, I'm actually more bothered about where my car is going than knowing the engine temp and RPM. Its more about 'feel'.
Just my two cents.
