CONTROLLER / TRANSMITTER - ADVICE PLEASE

[DroneSA]

Hi
I have a Huanqi 899B quadcopter. The controller doesn't power on and one of the control sticks (stick rocker?) is broken. So now I'm thinking of sourcing a new controller. I have heard that, typically, the controller needs a corresponding receiver on the quadcopter, so it's not as simple as simply purchasing a new controller / transmitter. This brings me to two considerations.
1) Do you think that a cheap hobby drone such as this Huanqi 899B would go to the trouble of having unique transmitter / receiver pairing? Perhaps such a mass manufactured product might have identical components in every unit sold and therefore I should be able to simply purchase a new transmitter? I have to pair the controller to the drone each time I fly it, so the frequency is set each and every time.
2) If I am forced to purchase a new receiver, then surely I can purchase any transmitter that is associated. What should I look out for on the drone to know whether I can do this? Should it be a simple matter of removing 1 receiver and connecting another? Or are there other considerations to be aware of.

Any advice is welcome

1). Agree probably can pair with any transmitter from same brand look like replacement one here http://www.heli-parts.com/f0784-rem...erial-drone-aircraft-spare-parts-p-15854.html

2) yes if the rx and tx have a compatible protocol then they can bind and tx can by definition transmit something the rx can understand. In general same company means it will work but spektrum has some transmitters that support dsm2 (older protocol) and most support dsmx now (newer protocol). Personally got a Jumper T16 recently which has a 4 in 1 radio module that can connect to frsky, spektrum (dsm2/dsmx), Traxxas, anything based on nrf and a slew of other receiver types and it runs OpenTX firmware which is open source and customizable. I would not get a better TX unless you plan to switch over to using betaflight based flight controller as well since you'd need to be sure the receiver is sending data to FC with a protocol understood by the flight controller in this case likely something proprietary or unknown, with betaflight based FC can configure all this and what switches do etc.

Thank you so much for your input. I had come across that website while trying to search for spares, prior to posting here. Clearly I am terrible at online searches - all I found was the entire drone kit from that website. So I truly appreciate that link. I'll contact that store and see if they ship to SA. Maybe they know will know the answer to my first question as well. (same rx but different tx). Failing which I may have to consider No:2.
