Bladder tubing tank with Wasp .061?
Will one of thease style bladder tanks work with a throttled engine?

It looks like a great way to save the weight of a regular style tank!
It looks like it will solve balance problems too because it can be placed over the center of gravity and feed fuel under presssure.
It says it should be in a tube of some kind. Maybe some light sheet foam rolled into a tube would work for that.......

Generally speaking, no. It certainly won't work for an airbleed carb and even with a two needle you are likely to have midrange problems. The pressure is too high, and none of the carbs are designed for it. If you were to add a pressure regulator to reduce the pressure at the carb, you might have a workable system, with some experimentation.

It definetly will not work with a throttled engine. No maybe about it. Those bladders provide a very strong pressure and are only good for engines running full out for the whole flight. It'll flood horribly the first time you try to go to idle. Or if you manage to start and tune it at idle it'll starve immediatly when you try to go up.
CG shifts from fuel use is not a big deal for our models unless you're going for some sort of endurance record.

Andrew, Thank you for the heads up.
We had some growing pains with the new site and this must be the lastest. We are trying to get in contact with the new hosts and get going again.
Other than some email problems and now this I have been happy with the new format and it has more stuff and more capabilites I can use when I get time and more training.
