I've read through many posts here. What, in your opinions, is the minimum size of an engine to be considered a "Large Engine"?

Things that make you go hmmmm

(I'd say the min is a Saito 1.80, for example)

To me its anything bigger than a 1.20 cubic inch/20cc

Gas - like a G23 and up
Glow - like the big ST's or Moki's and the large 4 strokes (1.50 and up)

I agree with Andrew.
1.20 size models tend to be the minimum for gas engines too which confirms the division point.This may be changing slowly though,as technology continues to shrink and lighten made for purpose gas model engines.
