Hi -
I just finished installing a tigre .61 on a Hangar 9 f22 raptor (it had a .46 before) I left the same tank that was there before and it's an 11 oz tank. What size tank should a .61 have?

I know that the smaller the tank the shorter the flight, and that it all depends on how I fly, but as a general "rule" what should it be?(for a .61)
