My bladder is old and needs the surgical tubing replaced the pressure fades a bit much causing lean outs mid way through the run.. so I fabricated a micro size fuel tank that could yield some reasonable run time and fit within this small airframes fuel bay. I had used a modern 1oz tank as my inspiration for the mid size 3/4 oz tank as a step down for a .049 and now with some help from a cork a .020 tank perhaps a 1/2oz. very light only 5.3g I plan to tap the engine shown for crank case pressure. The void in the back plate will be filled halfway with some epoxy then drilled and tapped giving the pressure nipple plenty of bite. I hope to be able to taxi / take off with this set up with the bladder the exhaust throttle would allow the engine to load up a bit. Perhaps this will be more consistent through the power band using this wee lil hard tank a perfect size for great duration with the .010. and perhaps 4 mins. with a some throttle play using the TD .020 will see how it goes.
