what we are trying to say is that even though you got them for free on a trade those birds are not worthy to be learning to fly on. you will need at least a 6 channel radio that does helicopters. get that first then go for a kit. helifreak.com has all the info you need to set up a helicopter or ask a local flyer to help.

good luck and welcome to the club. warning this hobby is very addictive and costs alot of money. be prepared for alot of ohhh's ahhhh's. very exciting stuff.
