The irregular spacing and beeping is due to low remote control signal levels. Any time the signal drops below 85%, it will start beeping at you to remind you to point the remote at the aircraft. The responsiveness of the system drops off very quickly after 80%. 40% is likely almost not operable.
Use the directional indicator under the status bar to keep it centered. It makes a really big difference. We didn't put that in there for fun!
