Yes they will!
When both are running it flies quite decently with the 26's, although you are frequently reminded that you are on the very low end of the power band. I had a lot of fun with mine, and the fuel tank size was never an issue. one thing to consider, that if you lose one engine, one 26 will not keep it in level flight, and it will start downhill. If you try to hold it up, it will stall and spin. It is not difficult to fly on one engine, but altitude is definitely your friend.....
