My i2 came Wednesday and this thing is a blast. Did a few test flights after setup. I then bounded the i2 to my p4p remote and connected the controller to an 11dbi Omni directional antenna for rx with 1 watt amp mounted at base of antenna in the tree and a 9 dbi omni on the house for tx with no amps. I zipped out over the countryside 55 to 60mph and hit 18,00ft in no time.Never a drop in signal. I use a tablet then hdmi out to a 50inch monitor at my desk. I do not see range being an issue being as I have 120 total feet of extension cable to my antennas. Of course set to 2.4ghz. I use channel 21 and lower the bit rate down. Will be testing range when batteries are broke in.
