That seems off. The VVRC 40 twin is 44 ounces AUW and is a proven performer with 21" size props. Since it is both cheaper, proven, and well supported I would go with that motor.
My crew is hitting WRAM on Friday. Beat the crowd and weekend craziness. Don't be surprised if there is not a definitive answer from that show. VVRC is not represented to my knowledge, and DLE will only be represented by a vendor. Horizon (Evolution), Hobbico (O.S.), DA, and I think bp hobbies (RCGF) will be the people you can talk to about their engine lines. Hobbico might have the DLE line as they do sell them. To be honest I have only spent minimum time in their booth as they don't seem as 3D oriented as Horizon.
As far as your earlier question about dead sticks, I have not managed to do that yet with mine. I did have a plug come undone (my fault, did not realize they twist lock in) and it ran on the one cylinder to a landing.
