Hi, welcome to RCU. If I understand you properly you are asking where to get that particular TX , RX , and batery?
I can't get the link for some reason , but probably any 4 channel system will work. It should include the TX and the RX at a minimum and can range from $20 to hundreds. The power batery will be purchased separately and most 3s x 2200 packs would work , but the dimensions and specs should be verified first.
I looked at the link and can't quite tell if it needs a 4 channel or 5 channel. Maybe a 6 channel should be bought just in case.

Your post above indicates a 4 channel TX , and a 6 channel RX.
in the manual it recommends these transmitters and receivers. the plane can move the ailerons, elevators, throttle and nose-wheel. I got this plane from a technician at the dutch airforce and he said it was a 3ch plane but it would be better to buy a 4ch transmitter..
