Are you gonna put smoke on the KingCat? If so, Gary Mueller makes a 48oz tank that fits in the area where the 16oz was. I've seen you fly, that being said, you might want to start off with 6 min on the first flight and adjust upwards as needed to get the most flight time.
If this weather ever settles down, Dan and I are gonna make to Ft. Bend.
If not, see ya at Mississippi.
