Hi Timbo, Reassuring tests... I have a DX7 with AR7000 and AR6200, both of which have more range than my eyes. My friends with DX6i's have pointed out that the geographical zone can be user set on their TX's. I have a fair amount of experience in long range WiFi applications and equipment purchased from USA is invariably 2 or 3 times more powerful than its european equivalent. They have suggested that if range becomes an issue, try setting the user zone to USA. This could potentially increase the output of the TX. However I have no way of testing this theory. Maybe you could shed some light on this. Regards Darren Hill
