I've not had one issue with the 4PL. Its comfortable, reliable and easy to set up. I love the internal antenna, small receivers that you can get for it that cost under $40. I've ran my Futaba equipment in everything from a lightened F104 to a loaded SCTE running a RX8/4600 combo, a Savox high torque servo, motor fan and transponder. I added a glitch buster and haven't had any brown out issues. I've never had control issues at distance.

The radio does all this with just 4 AA batteries too

I would highly recommend the 4PL to anyone.
