this is great advise indeed, i studied all related posts, /threads from 2002 till 2017 which could help me to understand this plane, and know about the nuances, problems, maintenance issue, operating techniques etc , made lot of notes , and came to the conclusion.that ;Intercoolers and Speed Brakes/Spoiler; are must have
its not about ;if i plan my descends well ahead, i do not need spoilers, main purpose for spoilers would be to descend fast thru icing .My business trips will be Poznan- Milan( Malpensa) and even in summer over Alps we do encounter icing ;-(((
yes wing lets, and STOL mods may be just cosmetics, and nothing else
By the way ,already bought the inter coolers
