We done the step 3 only of the page 29 iS/U-04 because we could not install the upper firework assembly in the fuselage because the fuel and break system are not done and it is too difficult because of the area. On page 29iS/U-07 we did the steps 1, 3 and 4. We don't have any problem with these steps, but before to everything we deburred all the parts.
