My first involvement in ultralight flying was 1988 - 1990, from memory it cost me about $40 a year for membership of the AUF. This allowed me to fly to 500 feet, no magazine no 3rd party insurance and there were many fatalities. I ceased flying in 1990 and quite by accident resumed in 2007, $160, 5000 feet, a basic magazine, wider choice of aircraft and now some 3rd party insurance, 10 000 feet. It is just my personal opinion but $185 seems like a reasonable deal to me, I pay RA Aus about $5 per hour per year.
I wonder what the members who say this is excessive think would be a fair price and how the membership cost of RA Aus compares to other similar organisations e.g. gliding or motor sports?
