All-Aircraft-Simulations

A little information: i have installed beautifull Campaign Ki-44 made by lectron and find in M4T in 4.10.1 without DBW but afer have installad proper map and plane and i have seen that in take off formation the planes are setting in linear front line but in diagonal line. This kind of formation is due to DBW or there is another fact that cause this new formation? The distance between one planes and others is great so that some planes are situated out of the take off stripe. In the mission i have not see any code referring about this new different formation.
Thanks for any informations about and sorry for my bad english.
