I have received a weight breakdown from one new owner .
9 lbs 4 ounces total inc spinner.
so----add to that the radio and engine and bits and pieces.
The lightest engine which will fly it around represents a 2.5 lb package.
The lightest engine developing enough power for some good aerobatics will go higher.a 3.5 lb package.
A rip snorter will hit 5 lbs all up.
Best guess is a 16-19 lb model - depending on who does it - realistic weights.
Pitts really suck up power if you want solid aerobatics -so - go for the lightest -strongest power setup you can find.
It looks like it wil be a lot of fun.
