Sven and Fred,
Thank you for your reply. I will try the archives but I think the SR3000
with constant speed must be a very recent option. With the trigear clearance
should't be a problem if I were to choose the 1700mm, but I don't really
know at this point. I know in theory there could be a little more noise, but
is that a problem ? Weight is important to me as my empty cg is already
quite far forward.
Actually, I find the cockpit noise quite loud with my headphones off, but
who knows how much of that is wind, engine, or propeller noise. Another
consideration is reduced drag when in glider mode.
According to Bryan Allsop the 3-blade SR2000 is much smoother than the WD he
had previously.
I have all winter to think about it.
