Fan was bad and rattling inside the unit. Had to replace it. Otherwise, haven't had any issues. I like that's there's port holes at the top to add your sma antennas if you wanted to change them.

Great radio, wonderful gimbals ... but lots of setup required, the only model on the radio had the mixes configured incorrectly with roll on left stick where yaw should of been. Also had to setup all switches. Not nearly as out of the box ready as the RadioMaster stuff but overall I really like the radio and glad I took the time to set it up and keep it.
