It is important get a good Warranty and good Service when you buy a Radio. If you have a problem with your radio and the manufacturer Repairs or Replaces it, that is worth the extra bucks. There are a variety of reputable RC Radio manufacturers to choose from. If you go too cheap, you may regret it.
I do not like crashing any airplane, even the foam ones. I want a radio that is Reliable, Feels good in my hands, and has the features I like.
That's why I have flown Airtronics almost exclusivly since 1984. I have experienced very few problems, and when I have had problems they resolvd them immediately at minimal expense.
I have purchased six Airtronics sets over the years and most have never been back to the shop.
