.....some baseline is required for your info to have something to compare your numbers against. Basic testing 101...
The baseline for comparison is the OS 120AX. I'm comparing engines, not props. As noted, the DLE is 300-500 rpm slower with the same props and pipe, depending on nitro content. Basic enough for a general comparison of two engines I think.
your right, but the O.S. is heavier and need a larger Tanks, meaning total weight is up with O.S. bin there, tried that.
