By The Numbers...
Just having a bit of fun on a winter night here, tell me what you think...
I have Sig's Sukhoi ARF (the big green one) almost built.
I don't have an engine in it, and I'm passively wondering about two engines for it.
Observe....
Sig Sukhoi SU-31
13lbs - 8oz weight.
Specs call for 2.4 cu in gas engine.
Candidate Number One
ZDZ 50NG
3.4lbs all up
+25% displacement over Sig's spec
$585.00
Candidate Number Two
Zenoah G-45
4.63lbs all up
+15% displacement over Sig's spec
$0.00 dollars because I already own it.
In short: The ZDZ lightens up the airplane by roughly 10% over the G-45, and provides a 10% displacement increase over the G-45.
But it's six hundred freaking dollars. [:'(]
So by the numbers: Would you...?
