RE: Turnigy H.A.L. (Heavy Aerial Lift)
My H.A.L. was outfitted with the HK [link=http://www.hobbyking.com/hobbyking/store/__23792__9_Mode_Multi_Colour_Multi_Function_LED_st rip_with_Control_Unit.html]Multi Function LED Strip[/link] which has 9 different LED modes controlled by a spare switch on the transmitter. The combination of front LEDs and the rear plastic ball drastically improved my flight orientation at a distance.
I also added some foam walls to protect my 5.8AH 4s Lipo pack from the 35 degree temperature. It seemed to work well for the entire 9-minute flight. I also changed my 5.8GHz FPV antennas to the circular polarized [link=http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=40&products_id=1058]SpiroNET Antenna Set[/link] from ImmersionRC. The circular polarization reduces interference and unwanted multi-path signals.
I haven't gotten my GoPro2 camera yet but I will post some video from by backyard flight.
