cherokee180c -> Hacker 20-20L Prop? (5/13/2008 4:02:37 AM)

What prop are you guys running on the Hacker 20-20L and the Extra Stiffy? The manual says an 11x4.7, but serveral guys have told me that is too much for that motor. Is a 10x4.7 a better choice?

I have been running 11x5.5, I believe thats what OMP recomended when I ordered it. Hackers are usualy pretty under rated.

You can run the 11 and we have. I don't do any current measurements so I can't tell you what the most efficient prop combo is. We also use the popular 10-4.7 GWS props in a pinch and they seem to work well also. Except they are a little more flimsy than a good APC-eprop.

I like the apc 10 X 4e or 10 X 3.8e. The motor will pull more, but the quality of flight goes down IMHO.
