BarracudaHockey,

I'm not trying to knock the 2.4 technology. I think it's cool but there is one drawback to it, line of sight reception. When I taught myself how to fly RC (trial and error) I flew my Pilot 40 trainer behind a tree line by mistake. When I lost sight of it I didn't give up on it. I was able to recover it and bring it in for a landing. I think if I had a 2.4 system I would have lost it.

High frequency signals don't propagate around objects as well as lower frequency signals. I think that's why antenna placement in a 2.4 system is critical.


If they're using 2.4 in jets then range should not be an issue as they take up a lot of airspace.
