Hi, i was unsure where to post this question, and since it relates to plans for a future scale(ish... i think) build, i'll put it here.

I've been looking at the great planes .20 size t-craft kit for a while, as it looks like it would be a fun bird, and a good excuse to break into 4 stroke engines without breaking the bank. but as i get to looking around at my engine options, i find that OS only offers down to .30 in 4 stroke (which is the highest the plane is rated for in 4 stroke). and saito only has 4 strokes down to .40. am i missing something? not looking in the right places? or is a 4 stroke with less than .3 displacement a figment of the designers imagination?
