Hi Mike. I've had very good luck with both DuBro and Hayes tanks. I have a 14 oz Dubro on my OMP Yak and it has been fine. I have 2 different Hayes 16oz tanks on other planes that have worked well. My experience with the 110's, (I have 3), is that you should richen the regulator before you even start to break it in. A good starting place is 3 turns out from closed. That will put the regulator screw a bit higher than flush which is what the instructions say. They are awesome engines. You will be pleased.
