That's not really considerate now is it. This may end being a amazing aircraft but priced at $150 not many people would be able to afford it and quite frankly people may not buy it if it's over $70, I know that I won't even if it's amazing, also charging for updates probably wouldn't be viable as you couldn't have the first version of the aircraft with many bugs and have to pay $30 to update it to fix the bugs. Hopefully IXEG will consider everyones financial circumstances, so we can all fly in the sky .
