Hi y'all great flyers

What is a potentiometer in Tx, and what is exponential? What are the pros and cons of those. I have read about exponential that it eases the servo movement and makes your flying more smoother and easier. I have never used exponential infact my radio does not have it. Future radio hopefully is 2.4 Ghz but I'm scared of radio's locked out.

Spektrum is coming out with another great new model of their I think DSM series, has anybody known anything about it. I know it's coming out after 2 months. Sorry topic was different but I also wanted to ask about brand new radio of Spektrum which is being released after 2 months.

Thanks for your input, as I love to learn new things.


Happy flying

Mody
