RE: Picco P-zero 0.8cc
DD, My comment on flipping the lecky prop was intended for AW's 10" diesel/eletric - in fact I can't even get the electric props out of the bag without cutting myself.[:-]
I am very familiar with the 4.1x4.1 lecky.
Have more than a couple laying around. It has been the prop of choice for my lehner/lipo avionik stinger. Not sure what it tachs out to but has been clocked at 134 straight and level. It is about 4 seasons old and running "old school" lipos.
can youcompare thisphoto with yours?
a 4.2x4 and a 4.1x4.1
