RE: To de-fuel or not to de-fuel that is the question
G'day Mate,
If the water didn't mix with glow fuel, & we could just drain it away, that would be fine, but it does, & the glow fuel degrades silicone tubing, so I always defuel, at the end of the day, & run my motor out of fuel, & add afterrun oil.
But you are welcome to do whatever you want with your planes.
