You may not care about the 4PLS because you have a 4PL, but there are people that want to see the drop down on a 4PLS before they buy. Since the 4PLS is the new replacement, we need to confirm that the drop down will work on both or else additional costs on two different drop downs and for us to buy two radios for this project.

Right now the 4PL has been flagged as discontinued at Towerhobbies.
