Max Fuel Tank Size?
Ordered a Magnum .91 4-stroke this afternoon and was reading the manual that's available on line. In the section on fuel tank selection they make the following statement:
The size of the fuel tank used should be 12oz. - 14oz., depending on the
model and the length of flights desired. Use of a 14oz. tank will provide
between 10 - 15 minutes of run time at full throttle. Use of a fuel tank any
larger than 14oz. can lead to excessive leaning of the engine during flight
and is not recommended.
Trying to think this through, the only thing I can come up with is that the engine may not be able to draw fuel correctly from a nearly empty fuel tank whose volume is larger than 14 oz. Am I on the right track? I tend to fly very conservative, usually land after about 9 to 10 minutes, and normally with at least 1/4 tank of fuel left. Would the 14 oz. limit still hold true in this case?
