RE: Parrot AR.Drone 2.0
Hi,
What is your distance between the AR.Drone and tablet when you have connection issues? I have found it best to disable my wireless router to my cable modem when flying indoors due to the unwanted signal strength. For outdoor distance improvement, the Belkin Range Extender has worked great!
I did not like the VGE High Performance propellers as they made my AR.Drone get unstable but the Gear Bearing Upgrade has worked out nicely.
I would recommend reading posts on the AR.Drone specific forums that I linked above. There is good information in those forums but be careful not to believe everything you read until you hear it from multiple sources.
Good luck with your AR.Drone 2.0 and Welcome to RC Universe!
