I have a 4PKS coming and I spent some time reading the manual, even though it's very similar to my 3PKS as far as menus it was good to read through it. Be sure to set the servo response speed correctly for analog or digital servos or you'll toast a servo.

The 4PL is a great radio and probably the best in that price range in my opinion. I was about to order one for my son but with the 4PKS free RX promotion I couldn't resist and am giving the 3PKS to my son.

The 4PL menu is very much like the 3PKS and 4PKS and is very intuitive. I don't know what you had before but you won't regret getting this system. It's a lot of TX for the money, enjoy.
