cant go wrong with a radio master pocket for a solid, inexpensive, entry level radio that will work with other drones as you grow. note it dose not come with batterys. make sure you order a pair of 18650s form a reputable source.
if you want to skip the pocket and get a radio you wont out grow i recommend the radiomaster GX12,TX15,boxer, GX15 too new for me to recommend ATM, the only difference that really maters is there ergonomics hand feel and button placement. buy ounce cry ounce
