OK, this is a legit question

I have read many bits and peices about the newer widebody planes for competition. It seems that the goal is to acheive good slow pace to the whole sequence. uplines, downlines, straight and level flight.

my question is what makes this possible and in what combination.

widebody design - more physical displacement of the air?

drag - such as fixed gear, cowl cheeks?

wing area and wing design?

overall weight - 9lbs vs 11lbs?

2-stroke vs 4-stroke?

prop selection?

I fly a Focus/Webra 1.45. it seems that compared to a Smaragd/YS 1.40 that the Focus flys much faster.

so 'cmon all you Jedi masters, please share with us your knowledge.
