1/16 must mean Tamiya. I have been thinking about getting one of those tanks. I have a few Tamiya's. I built one of their Semi's (with the light/sound kit) and have some of the classic stuff like the Bruiser, Sand Scorcher and Rough Rider. I have WAY too many 1/10-1/12 on-road, off-road, buggies, trucks, pans, tourings, etc. I started getting into 1/8th on-road and that's where I put a halt to the addiction. I don't really have time to run them anymore, but just can't bring myself to sell them.

You could use the airbrush on the needles. I didn't due to the amount of masking.
