hello new to this hobby and i have got myself a p2 with gimbal, next thing i want get is a monitor/reciver and transmitter, which ones should i consider ? Another thing i am not sure about is if i get a monitor/reciver with twin antennas and i decide to to upgrade them to circular polarized ones I see that they come in pairs tx and rec, so do i have to buy another pair so one could be fitted to replace the one thats left on the monitor, or do i just put an upgraded one on and leave one of the original ones on, if that would be the case which one do i change on the monitor , also is there anything else i need to finish the job off
