Andy mine has a DLE 55cc in it, your 4 stroke will sound good in yours. I spent 5 yrs. building mine and I'm afraid to even fly it. Being an old guy I'm not sure I could keep up with 120 MPH which it is capable of, 90 MPH is even fast for me. Yours will get it on also. these are fast planes and my paint job is very slick reducing alot of drag.
Hope you don't mind, I thought you might enjoy some pictures of it.
