There is another pair of spoiler holders that came with the kit and can be used to raise the spoiler. I should change them later. It looks better with a higher spoiler. Thanks for the tip.
Just changed the spoiler holder to a higher one which is M11 in the manual. The height of the spoiler increased 0.5cm. If you are building an Avante, do not use M1 part, use M11 instead.
beat, just spray yellow colour first. When you spray yellow colour, start from the middle of the shell and move to the rear. No need to cover the front shell. Just spray the yellow colour bit by bit and leave the front clean. After yellow, just spray white. It is very easy.
