The motor in front pulls better.
We'll have to agree to disagree on this point! I actually did some tests on the single Pulmore motor SD-11 engines as I had a customer that wanted to upgrade five of them. Obviously, a second Pulmore motor was not an option in these models due to the narrow shell.
However, just turning the engine around and running it in reverse putting the motor in back increased it's pulling power by over 30%, a significant difference. I did the same test with the Phantom before I did my mods and got similar results. If I currently had a single Pulmore motored unit, I'd do the test again, but I don't. However, I'm pretty convinced that the tests I did were accurate.
