good choice man i just got my in the mail yesterday and the quality is pretty good and the receiver looks good also not cheap looking ! The only thing you might to adjust is the throttle trigger because its kind of loose, i adjusted my tighter and feels great .

Usually yes the more expensive the radio is the better for sure my "futaba 3pk" . Which was $300 lasted me about 8 years intill now it has a bad delay so it was time to get a new radio. But airtronics quality is good so it should last pretty long.

The best thing to do is to keep your radio clean on the outside and the inside if you want it to last long .
