Im on a quest to make my 30cc GeeBee real fast.

SO I had a 18X14 wood zinger pro laying around.

On the DLE 30cc it only did 5800rpm

But on the big DLE 55 it hits 7500rpm like its nothing! and Still has a nice low idel

The spec's show this as max rpm, I don't know if its HP or timeing of the motor thats keeping it at this RPM but it sweet!


This Combo has a prop speed of 100mph

So with slip and drag depending,Im thinking it will take my bird in the 75 to 80 mph range.
