Here's a question / observation that I would like to bounce off the rest of the R/C commuity in hopes of confirming for finding an answer.

I have observed from sound and site that most fairly large planes running 2-stroke .60+engines tend to accelerate downline speed and engine RPM more than 4-strokes. Is this common knowledge and if so what causes it? Is it just that the 2 strokes due to the (2-stroke design) tend to spin-up easier when they encounter forced air via the downline? Additionally, it appears that glow 2-strokes are affected more than gas.

My comparison is genreally between ys.63 - ys 1.40 vs. moki 1.80 - 2.10. My statement about gas relates to my experience watching TOC in person.

What are you thoughts on the subject?
