OK .  I am finding some info.   But I still do not know if its for gas, and the tanks only go up to 12oz.

I have a little info. Normally, gas engines do not need bladder tanks since they are pumped, . I have only seen bladder tanks in use with pattern flyers (glo engines) and pylon racers (glo engines). I have used them in both situations, love them in my pylon racer (more consistent fuel burn). I think its overkill in my pattern plane since I am running ys (pumped), but hey it cannot hurt. I use Tettra bubbleless tanks. I do not believe they will work with gas.

So, may I ask why you think you need one?? I see guys doing some pretty radical maneuvers and never have a fuel proplem, except for one guy (who will remain nameless because he should have known better) who had mistakenly replaced his fuel tank tubing with glo tubing instead of gas. It got stiff as a board.

MY 71" Slick (DLE30cc) Has a 20oz tank. but I am forced to stop arobatics at 1/3rd. tank or I will dead stick.
Half a tank is the sweet CG and than a few min. later it starts that miss sound. than its level out and set up for landing.
This is Ok, I just thought why carry an extra 6 oz. of fuel around I can never use.

What I am doing now is ,Pulling the tank to check for anything wrong , and Getting fresh 93 octane gas ,  and than resetting carb. 100 RPM on rich side of low and high thro. 
  I pulled the spark plug and it had that tan/yellow look that DLE says i am supposed to have. so I do not think resetting the carb was my problem. But you never know.

sounds like you have a plumbing issue... on two different gas engines i have run out of gas in the air, and both tank were empty

Ok  Everything is perfect.

It seems a little bit better. I will not Know till I fly again.     The dead sticks happen after violent maneuvers , and than I hear the power loss . Of course I always point the plane in a down line when this happens .
 
I have idle down at 1640 RPM. When Off  2500RPM. Do I want to up my RPMs?

I agree, I flip and flop a lot and my dead sticks have come back bone dry. Some of the guys are using a poulin chainsaw clunk but thus far I've found no need.

My guess like others is that you have a plumbing problem

For the record, the original bladder tanks were used in CL, mainly in combat. They were pen bladders filled with fuel. Now the modern bladders use surgical tubing. Very great method for providing fuel.
The other bladder tanks, use a baby bottle bag inside of a regular tank. All of the air is evacuated when filling fuel. this eliminates the possibility of an air bubble hitting your carb.
Neither of these are needed with a pumped gas engine. And I doubt the materials would work with gas anyway.

when im flying i bump my idle up higher than normal.... when i was learning about gassers(still am) i used to keep my idle as low as possible and i did have a couple of deadsticks while doing violent blenders and flat spins.... not any more

you might want to look into walbro felt clunks... its all i use now on my gassers, they retain fuel in them so there is a less chance of sucking air than a standard clunk
