The quality of the image on the Boostervision camera is just "OK", 300 lines resolution, I believe. I would suggest getting the high power transmitter and RX option. The camera is also sensitive to noise from the ECU, impacts image quality. Low power system range is 1000 feet at best and the high power unit maybe 1/2 mile at 400 ft altitude or so. I had a hard time maintaining a consistent image quality when doing 'hard' aerobatics and at low altitudes (under 200 feet or so).

I have since gone to a 'professional' 900 MHZ based system using a MaxStream transmitter and receiver attached to a Sony DVC and encoder. Not for the faint of wallet (total cost around $800) and weighs about a pound - but I've since flown it to 44,000 feet and Mach 2.1. This also requires a ham license to operate, but the image quality is awesome.
