Corona does not come with a radio that you have to purchase separately,again this is something that you have to decide on yourself and how much money you have to spend.Around here the consensus is that the Futaba 9chp is the best but it is also one of the most expensive,I own it and love it but it was not what I started with that was a Hitec Eclipse 7 which was a good radio but the 9c is all that I will ever need.You need to do some research on radios on the net and find one that you like you will need at least a 6 channel to fly the corona and some of the more advanced heli's although I don't exactly know how many channels is needed for the corona but I don't think that it would be more than six but the bigger radio you purchase the less likely you would have to purchase a upgraded radio in the future that is why I and many others here say get the 9c if you have the money in the bank.
