Someone said B KEG for beer drinkers. How about BEER?
Or for Beer drinkers how about BURP?
Then again there is BUTT. Or, BANG and if you get a second helicopter how about BING? If you are into reading how about BOOK?
If the helicopter is used for heliskiing how about BRRR? If the helicopter is used in low flight application how about BUZZ?
If the helicopter is used for questionable financial purposes how about BILK?
Shall I go on?
