Correct grammar....



A dog You use 'A' for words that dont start with vowels....

An apple. You use 'An' for words that start with vowels....




BUT what about fpv?



I fly an fpv quadcoptor.



IT BREAKS THE RULE!

It depends on whether you're trying to say the actual letters "F-P-V" (eff-pee-vee: "eff" starts with a vowel) or if you're just using them to abbreviate the phrase "first-person view".

An hour? Maybe it is the pronunciation more than the spelling.

According to my wife, the proof reader / copy editor, with the "Hoity-Toidy" Masters Degree in English and Creative writing, The Chicago Style manual says you'd use "An" in this case. In the sentenance "I fly _ FPV copter" using "A" instead of "An" would be awkward. then she said something about using it befor an acronym and something else but by this time I was watching a funny shadow on the wall while singing the theme song to the Bradey Bunch in my head. Seriously ? I would just say, I fly a *&$^^% FPV @#*% Quadcopter! lol,lol....but then she would yell at me.... Boooo....
