I have a DLE-20 in my Pulse 125 and can report it flys nicely with it but I found the install inconvenient due to space limitations. The stock gear sweeps too far back for grass but is reported to work fine on pavement. I've never flown off pavement and cannot say myself. But I think the DLE-20 is overkill on this plane and would imagine a nice 120 four-stroke would have been better.

If you fly it constantly you will enjoy the fuel savings. Consider dual elevator rods as well.

Good luck with your Pulse,

The included nylon engine mounts broke on a hard landing and I've gone back with a cast aluminum mount.
