try opening and finish 8 gears doors made of kevlar and carbon fiber (you never get rid of kevlar fuzz), then hing properly for scale appearance, end then make instalation of horns and cylinders, without plans and aiming scale functionality!!That's a nightmare that i´m having with Fiberclassics MIG 29. anyway, gear doors are the most bothering tasks when building scale models!
for an acrobatic model, i have no complains, i love everything, even installing around 20 hinges!!
