MK58 substitute?

[cabinfourus]

I own two Q500 drones. I am missing the MK58 on one of my drones. I have been looking online for a replacement and see they run around 80-90 bucks new. Does anyone know if there are substitute downlinks for this drone? I see some 5.8Ghz downlinks on eBay for around 20 bucks that work with GoPro but I want to be sure the signals won't cross. If anyone has one they would like to get rid of just let me know. Also, does anyone know how this thing works? Where does it get its power from?

EBay had that not too long ago for $29

Other 5.8GHz downlinks may be analog transmitter. For those you need an extra monitor or goggle.
MK58 uses WiFi connection to ST10. ST10 does not allow third part transmitter.

I thought this might be the case. Yuneec has a way of making their drones expensive to repair.
