Sullivan flex tank experience?
I am considering a sullivan flex tank for a 1/2A warbird. The space between the firewall and the next former is less than 3'. I can fit a 2oz tank, but I'd like to have a little extra fuel. The sullivan slant flex tank 4oz is advertised
to be deformable and can be reshaped with a heat gun. Any experience/suggestion? I am planning to pu a .15 engine and would like to fly ~ 6 min with some fuel to spare...
Thank you
