I have seen some posts about this happening, but the concern was just around warranty as you would need to take it back to Canada for the warranty to be valid with an address somewhere there.
The RC Pro 2 is 'supposed to have longer range' and that may be due to its antenna configuration. Both put out the same transmitter power 2 watts at 2.4 GHz and 5.8GHz however the RX Pro 2 has another channel at 5.1 GHz where only puts out 200mW...
Strange, my signal is much stronger with the RC Pro 2 as compared to the RC 2. Even when i tried it with an Air 3S, it worked amazingly. Only downfall of the RC Pro 2 in my eyes is the 4G block
Yes, RC 2 range is nothing when compared to the RC Pro 2 but in saying that, I got half the distance with RC 2 before disconnection which is just over 5km and for me that's strong enough - For Now
