Andy,
no rip off at all. This system is advertised as a perfect beginners system for flying…… The blurb I found also states that it requires 4 x AA batteries for the receiver. Price was £49.95.
I do know some sets are sold without receivers too.
And well, yes, you have to buy the servo(s) you need and the battery types you prefer, and a charger if required. Usually, batteries and charger are a one off purchase. At least the unit is made by a recognised manufacturer.
The AFHSS Lite4, 4-channel radio is the perfect transmitter for beginner pilots. With its simple-to-use design and advanced 2.4GHz technology, this radio will have you flying a variety of models confidently and securely from a basic trainer to more advanced aerobatic-type aircraft. Coming complete with the Minima 6S Park-range, micro receiver, Hitec’s AFHSS Lite4 is your very affordable and straightforward radio solution!
Point to note – this is a 4 channel unit not 6 as you state.
