For those whith DLE 55's that want some speed.

I broke my nice 18X14 prop on a dead stick landing.

So I ordered a New 18X(8-14) prop and picked up 500 RPM's!!!!!!!!

My top speed is up about 9mph and it seems to have more low end grunt.

So Im at 8,000 rpm on the ground with this 18X(8-14) prop with stock muffler. Thats 106mph prop speed, with out slip and drag.
