RE: parkzone t-28 receiver?
I would buy the ready to fly, junk the radio (reciever/transmitter) right off the bat.
Why?
Because the PNP does not come with a battery or charger, which cost about $90.00 if bought seperate.
$90.00 plus $159.00 (PNP cost)=$249.00
Ready to fly cost $219.00
That's my story!
Of course if I was already into electrics and had a charger/battery then the PNP would be a good choice.
