I'm running 20ga... Made mine from scratch one is 47" the other is 49". I'm sure you could get away with two 48" ers. My RX is here. View attachment 32638

This plane builds out at 21 or more pounds. DA-60 with a pipe is OK power, but not outstanding. Most do DA-70 or DA-85. One guy I doing a DLE-85 over on the FG thread.
Tony at DA steered me toward the 70 and away from the 85 for this airframe. If going that big a single you may want to beef up the airframe a bit. Especially in the motor mount. Just in case! If you think you "Need" more power check out Jase's video. He's on a 70 w mufflers no can no pipe. Dunno but looks like it has plenty pull!

Depending on your needs I think a piped 60/ 61 should be fine. I went with the 70 to get into a twin and have a little different throttle curve. Good luck.
