Dle 30 prop size

[alex nicol]

I have a pilot kit bucker jungmann Span 82" and am considering powering it with a DLE 30. 

My question is what prop size would be best..... Current thinking is a 19 x 6

[steve too]

19x6 is a bit low for a DLE-30. Mine have 18x10s.

Hi Steve, 

Thanks for the quick response. 

My thinking was given the type of model my thinking was increase diameter and sacrafice some pitch

My experience with a 3w 28i would suggest 18x10 or 19x8 would be a good choice for your DLE 30. Clearly, it depends on airframe and also there are variations in  makes of propeller. I tried a Mejzlik !8x10 on Acro Wot XL, but found to my surprise that a Menz S 18x10 performed better.  

 

I would use a 19x8 on the Jungmann as already recommended.
