NRF24L01+PA+LNA with Antenna Range?

I was flying my Syma x5c outside yesterday for the first time with my modded devo thanks to the great work you guys are doing. The range was excellent, but i was wondering, what range do i get with the NRF24L01+PA+LNA module with an antenna at 90 degrees horizontally?

Here's a pic i took yesterday and my modded tx
