Dont know until someone tries it. I look for as big a prop as I can get and still get spool up....gets me out ot trouble when I need...otherwise give me good airflow over control surfaces when in low power maneuvering.

There are also two schools of thought on prop pitch...on my Saito profiles I love the 4 pitch. 6 and 8 are different feel, maybe for different style. Now on the other hand...I tried a 33x8 on my DA150 Extra....Did not like the run out feel...prop felt done at half throttle....could hover and do pogosticks with it but regular aerobatics were not as much fun...

My guess based on absolutely no info...the 19 might take it out of the power band...
