Les, i think so, at least with the Twinstar i believe that was one of Hobbico's goals to have it manageable with an engine out. I have had a dead stick a couple of times with Twinstar number 1 and was able to land without any problems. I had a 101" Ziroli B-25 the engines were set at 0/0 and it flew great, never had a dead stick with that plane though.
