Hey guys,

FWIW, I just test fit the Sullivan 10 oz. Flex-Tank, part number S728, in the SE. Only required minimal heating to the tank to get it to squat, slightly, so that the tank would fit through the firewall without modifying the tank shelf.

Just kept reinflating the tank during heating so that it kept about 98% of its original shape; i.e., no cavities.

There is actually room for the 12 oz. Sullivan Flex-Tank, part number S729. Anyone know if that would be necessary if using a 4-stroke; e.g., FA-72, to get approximately fifteen minute flights? Yes, I would be off of full throttle for at least the approach and landing phase...Or, would the extra two oz. of departure fuel just add insult to injury concerning CG issues?

Thanks,

Mile-Hi Flyer
